12.2 On-Site Service

12.2.1 Customer Database Backup (CDB Backup)

Definition

CDB Backup backs up the customer database (CDB) to a storage medium automatically and in cycles. Hicom 150 E Office saves the CDB to a flash memory card (FMC) every day at midnight system time, thus creating a backup copy of the data. (Hicom 150 E OfficeOne and OfficeStart save the data to the EPROM.)
If the control board (CBMOD or CBPC) fails, you can transfer the latest CDB to a new board. This requires that the FMC has sufficient memory for a CDB backup (at least 8 MB).
In Rel. 2.0 and later, you can back up the CDB manually, using Hicom Assistant T or Hicom Assistant E Office (in online mode).
You cannot stop a manual backup that was started with Hicom Assistant T.
After Hicom Assistant T starts a CDB backup, you should end the procedure again. The backup continues to run in the background.
You can also use Hicom Assistant T to manually recover a CDB from the flash memory card FMC
Reset the system to start recovering the CDB, which restarts the system (cold start).
When you perform an APS transfer, the CDB backup on the FMC is overwritten and is available again only after a manual or automatic CDB backup.
The system signals that a CDB backup is in progress by briefly extinguishing the run LED or the idle bar several times on the CBMOD / CBPC. The procedure takes approximately 30 seconds.
The CDB, including call data, is saved for approximately 100 hours in the event of a power failure.
If you are using an uninterruptible power supply (UPS), system operation is maintained for the period provided by the UPS in the event of a power failure.
During nightly CDB backup, the system first copies the CDB to main memory. You cannot make any changes to the CDB during this period (CDB access is denied for local and remote administration and for Plus Products for approximately 30 ms).
The system then transfers the copied area to the FMC (this is time-intensive and may take more than 20 seconds, depending on system load). After the data has been written, the system generates a checksum of the CDB on the FMC and compares it to the checksum in main memory. If the system finds an error, it repeats the backup procedure 3 times. If backup is unsuccessful, the system makes an entry in error memory.

12.2.1.1 Backing Up the CDB Manually on an FMC and Restoring It to the System Using Hicom Assistant T (not for Hicom 150 E OfficeOne/Start

This section describes how to back up the customer database manually on a flash memory card and restore it to the system using Hicom Assistant T. This requires an 8 MB or larger FMC.
 
Caution 
Always disconnect the system from the power source before inserting or removing the flash memory card. 

a) Backing Up the Customer Database Manually on an FMC:
Step 
Action 
1.  
Start Assistant T system administration 
2.  
Menu 28 -> Edit CDB 
3.  
Menu 28 - 2 -> Save CDB 
4.  
Menu 28 - 2 - 1 -> Save CDB to flash memory card  

b) Loading the Saved Customer Database from FMC to the System
Step 
Action 
1.  
Start Assistant T system administration 
2.  
Menu 28 -> Edit CDB 
3.  
Menu 28 - 2 -> Save CDB 
4.  
Menu 28 - 2 - 2 -> Load CDB from flash memory card 
Attention: When you do this, the system performs a hard restart. 

Reasons CDB Backup May Not Be Carried Out

Insufficient memory on the flash memory card.
The time following a system reload is also 0:00.
New APS in free area of flash memory card (memory full).

12.2.1.2 Replacing the Processor Board (CBMOD, CBPC)

If you need to replace the processor board because of a hardware fault, you have the following options for handling the CDB:

Loading the "new" CDB to the system after replacing the board
Procedure: Use Hicom Assistant E Office to make a copy of the CDB on-site and save it on an FMC. Then disconnect the system from the power source and remove the FMC. Replace the processor board and re-insert the FMC. When you turn the system back on, it performs a reload. After loading the CDB you have just saved back to the system, the hardware and CDR switches are active, but delta mode is not set. The customer system is now configured.
The CMI mobile phones are registered.
The V.24 (RS-232) baud rate is set.
The ACD login port is configured.
All telephone settings, such as volume and display settings, are configured for each station.
Loading the "old" CDB to the system from a customer disk after replacing the board
Procedure: Disconnect the system from the power supply and remove the FMC. Replace the processor board and re-insert the FMC. When you turn the system back on, it performs a reload. If you want to use an "old" CDB version in the system, you need to load it to the system without setting it to delta mode. The hardware and CDR switches are in active.
Then reset the system, after which the customer system is configured.
Attention:
Re-register the CMI mobile phones.
Reset the V.24 baud rate.
Reconfigure the ACD login port.
Reprogram all telephone settings, such as volume and display settings, for each station.
Loading the CDB to the system from the FMC after replacing the board
If you cannot save the CDB because of a hardware fault, you can load the backup CDB from the previous day to a replacement processor board. (the system saves the current CDB on the FMC every day at midnight.)
Procedure for Hicom 150 E OfficePro (Rel 1.0)
1. Disconnect the system from the power source.
2. Remove the flash memory card from the defective CBMOD.
3. Replace the defective CBMOD with a new CBMOD.
4. Insert the flash card in the new CBMOD.
5. Reconnect the system to the power source.
6. Execute a reload (hold down reset switch for 3 s).
7. If an "F" appears on the seven-segment display, briefly press the reset switch (resets the system).
8. The system boots with the backed-up CDB.
Procedure for Hicom 150 E OfficeCom and OfficePoint (Rel 1.0)
1. Disconnect the system from the power source
2. Remove the flash memory card from the defective CBPC.
3. Replace the defective CBPC with a new CBPC.
4. Unplug battery connector (X11) next to the buffer battery on the CBPC for approximately 20 s.
5. Insert the flash card in the new CBPC.
6. Reconnect the system to the power source without performing a reload.
7. The system boots with the backed-up CDB.
Then reset the system.
After you load the CDB from the backup area, the CDB in the system is a maximum of one day old.

12.2.2 Replacing or Upgrading the System Software

12.2.2.1 Speed Upgrade

You can use a speed upgrade to upgrade the software within the same release.

Follow the steps below:

Using Hicom Assistant E Office, make a copy of the current CDB on-site and save this CDB to a customer floppy disk (this provides additional security).
To perform a speed upgrade by replacing the FMC, first disconnect the system from the power source.
Remove the FMC containing the "old" APS.
Insert the FMC containing the "new" APS.
Turn the power back on; the system boots.

Because the CDB is backed by a battery in the processor board RAM, the CDB contents are not lost. The data in the customer system is the same as before the upgrade.

You can perform a remote APS transfer in the same way. This transfers the software over the phone line instead of replacing the card and stores it in an area on the FMC reserved for this purpose. After the data has been transferred, or after a timeout, the system switches over to the new software. The CDB remains the same.
 
You can perform a speed upgrade only within the same release, but not from Release 1.0 to Release 2.0.  

12.2.2.2 Upgrading the System Software

Follow the steps below to upgrade the system software from Release 1.0 to Release 2.0:

Read and save the old customer database using Hicom Assistant E Office.
Install the new Hicom 150 E Office software (by replacing the FMC).
Start up Hicom 150 E Office (with the default database).
Select the Convert customer database menu to convert the database (you must enter the old CDB and the version of the new system software).
Copy the converted CDB to the system.

12.2.2.3 Upgrading the System Software in OfficeOne and OfficeStart (Release 2.2 and Earlier)

In Release 3.0 and later, perform an APS transfer to upgrade the system software in OfficeOne and OfficeStart (see Section 12.2.2.4).

You can use the software loader (P30300-P1509-F1-1) to upgrade the software on-site. Set up the connection to OfficeOne or OfficeStart via the V24 adapter (ROW = S30122-X5468-X3, Australia = S30122-X5468-X300) to ensure a secure data exchange.
 
If you have a V.24 adapter of the type S30122-X5468-X1 / -X100, the load operation may terminate incorrectly, causing problems.
You need to customize this V.24 adapter to perform software upgrades without problems. Refer to TR No. WIT-99-00163 for details.  

Procedure
Step 
Action 
1.  
Copy the new system software to the Loader directory and start the loader. 
2.  
Connect the PC to OfficeOne or OfficeStart via the V24 adapter
3.  
Save the existing customer data (as cust1.kds, for example). You need to convert the data if you are upgrading between different releases (see page 6-26). 
4.  
Start the system administration from the system telephone. 
*95 Access system administration 
31994 Default user name (identification) 
31994 Default password (authentication) 
29-1-3 Enable the FMC for programming (clear the flash memory) 
Immediately afterwards, perform a system reset (disconnect and the reconnect the power plug). 
Note: 
If you are upgrading from one release to another (such as from Release 1.0 to Release 2.x), use the password for the earlier release (Release 1.0) to access the system administration. 
5.  
Select the new system software and begin loading it. The system then calculates the checksum. Click OK to confirm. 
Loading takes around 25 to 30 minutes. Do not allow a screen saver to activate until loading is completed. 
6.  
The system starts automatically, after which you must load the customer data. 
 
The system retains the customer data during upgrades within the same release. 
When upgrading between different releases, the country initialization procedure creates a default database. Afterwards, you must load the customer data.  

12.2.2.4 Upgrading the System Software in OfficeOne and OfficeStart (Release 3.0 and Later)

You must perform an APS transfer to upgrade the system software to Release 3.0 in OfficeOne and OfficeStart. Do not use the software loader for this upgrade.

You can do this in one of two ways:

APS transfer via the V.24 interface
Use the V24 adapter for this purpose (world = S30122-X5468-X3, Australia = S30122-X5468-X300).
Set the baud rate in the communication server and Hicom Assistant E Office to 19200 baud for short transmission times (30 minutes).
- OfficeOne/OfficeStart: Hicom Assistant T, menu option 22-13-1-3
- Hicom Assistant E Office: use the menus to select the program settings. The Communication tab contains the baud rate settings.
APS transfer via the optiset E ISDN adapter (not in OfficeStart) or the S0 subscriber port
Use this option for transmission times of 25 minutes.

Procedure
Step 
Action 
1.  
Connect the service PC to OfficeOne or OfficeStart, using one of the options described.  
2.  
Save the existing customer database (as "kunde1.kds", for example). 
Convert the database file if you are upgrading to a new release (see page 6-26).  
3.  
Select Open CDB from the File menu and select the APS file (*.fst) format.  
Open the fst file containing the new system software.  
Note: The fst file is reserved for in-factory programming and should not be transferred by the software loader.  
4.  
Double-click the Transfer icon:  
Select the access type and enter your PIN.  
5.  
Select APS Transfer. A new window now appears at the top right edge of the window. Here you can specify whether you want to 
replace the APS immediately at the end of the transmission,
replace the APS at a specific point in time.
6.  
Start the APS transfer. This will take roughly 25 to 30 minutes. 
7.  
At the end of the APS transfer, Hicom Assistant E Office reports "APS transfer completed successfully". This triggers a system reset, and the CS starts up with the Release 3.0 default settings either immediately or after the entered time.  
8.  
You can use the APS stamp to verify whether the new APS was activated properly. Use either Hicom Assistant E Office or Hicom Assistant T (menu option 29-1-2) for this purpose. 
9.  
Program the system password from an authorized telephone.  
10.  
Now load the converted customer database and define the hardware configuration.  

  The system retains the customer data during upgrades within the same release. 
When upgrading between different releases, the country initialization procedure creates a default database. Afterwards, you must load the customer data. 

12.2.2.5 Downgrading to the "Old" Software

In most cases, you can only upgrade the Hicom 150 E Office APS, that is, you replace the existing software (A) with a new software version (B).

However, if you need to downgrade the software, (from B to A), you must follow the steps below.

Example: APS version A is running on the customer system. It was upgraded to version B and needs to be downgraded again to version A.

To downgrade the software:

Disconnect the system from the power source.
Remove the FMC containing the current APS (B).
Insert the FMC containing the old APS (A).
Turn the power back on; the system boots.
Using Hicom Assistant E, load the backed-up CDB for version A to the system.
Reset the system.

12.2.2.6 Software Notes for Hardware Updates in a System

You should complete a planned hardware update before making a copy of a CDB with Hicom Assistant E Office. This procedure tells Hicom Assistant E which version of the hardware configuration is now installed (after an upgrade).

Do not perform any hardware updates between CDB read and write operations.

Hardware updates include:

Removing existing boards and inserting new ones.
Adding telephones and connecting new ones.
Disconnecting and connecting optiset E key modules and options

If you plan to update the customer hardware at the same time you upgrade the software, a speed upgrade detects the new hardware and incorporates it into the system.

Perform the steps in the following order:

Perform a speed upgrade.
Update the hardware.
Remove the CDB from the system and make any changes.
Load the CDB to the system.

Note the following when you add additional boards to the customer system or remove existing ones:

When adding boards, you can insert them into any free slot in a system, where they will go into operation automatically.
You can also append the ports of the new boards to the end of the existing ports.
If you place a new board in a free slot between existing boards in a system, the sequence of ports changes when the system boots following a reload.

Note: If an upgraded system triggers a reload, you must perform a reset in the system after loading the backed-up CDB (using Hicom Assistant E Office). The reset synchronizes the sequence of ports in the system.

After upgrading the software with a speed upgrade, the CDB in the system remains the same and no further action is needed.

12.2.2.7 APS Transfer (APSXF)

Function

The APS transfer replaces the application processor system (APS) in a Hicom 150 E system from a remote service center (remote service). The service center performs APS transfer via the integrated analog or digital modem using the Hicom Assistant E Office.

New feature in Release 3.0 and later
APS compression shortens transmission times by as much as 30 percent. CSTA over IP is available in Release 3.0 and later (see Chapter 13).

Requirements

You need two applications to carry out an API transfer: An application in the service center and an application on the customer system.

A flash memory card (FMC), or a soldered-in EPROM in OfficeOne and OfficeStart, with an adequate amount of storage capacity must be available on the customer system.

The write-protection switch on the flash memory card must be set to write enable (factory default).
 
All Hicom 150 E Office systems currently have a sufficient storage capacity for APS transfer.  

Refer to Table 3-8 on page 3-31 for a list of flash memory card models and their applications.

APS Transfer Using Hicom Assistant E Office: Procedure

1.  
In Hicom Assistant E Office, click the Open customer database button. 
2.  
Select the extension *.fst from the file type field. 
3.  
Select the folder that contains the.fst file and open the file. 
4.  
In Hicom Assistant E Office, click the Transfer button. 
5.  
Enter the access number. 
6.  
Select APS Transfer.
Note:
If the APS_Transfer field has a gray background, the fst file was not opened correctly. When you click this button, another window appears in the upper right where you can define the time to activate the new APS.
APS transfer can now begin. 
7.  
The transfer time may vary depending on the system. Generally it takes from 20 tob30 minutes with a ISDN transmission. Transfers using an IMOD modem, on the other hand, will take longer, due to the slower tranmsission rates of these devices. 
8.  
Following APS transfer, Hicom Assistant E Office reports the following: APS transfer successfully completed. A system reset is performed at this time and the system boots with the new APS either immediately or after the time entered. 
9.  
After booting, the system deletes the old APS. The delete operation takes approximately 7 minutes. 
10.  
To check whether the new APS has been activated, use the APS stamp function in Hicom Assistant E Office or Hicom Assistant T (menu options 29-1-2). 

APS Stamp: Explanation Based on an Example

Notes on Procedure "APS transfer"

At the beginning of the session, you must specify which APS you want to transfer and when.

The service center can cancel the session at any time.

If you select a complete APS transfer, the system application performs various tests. The following errors may occur:
If (Error) 
Then 
The flash memory card is not big enough 
Hicom Assistant E Office error message: Flash Card Too Small.  
Replace the flash memory card.
The flash memory card is write-protected 
Error message: Flash card write-protected
Remove the write protection.
The APS block is not a deleted one 
Error message: APS block not deleted.  
The system application deletes the flash memory block needed for the new APS (shadow APS block). This may take over 20 minutes, depending on the system load.  
End the session and try again later.
A write error occurs during programming 
Error message: Write error during programming
The flash card is defective and must be replaced.

If none of these error occurs, you can start the APS transfer. Hicom Assistant E Office asks whether you want to make a copy of the customer data as an additional precaution.

The application then starts transferring the subsystems. This does not impair switching traffic. The flash memory card is programmed with the data received.

Additional Notes

If there is a disruption during transfer (such as a line failure), you must start the transfer again manually. The complete APS is retransmitted.
You must wait ten minutes before another transfer can begin, since the incomplete APS must first be deleted from memory.
After an APS transfer, the system verifies the checksum. If it is incorrect, the complete APS needs to be retransmitted.
After a successfully APS transfer , the system displays the message APS-Transfer successful. You can now end the session.
The system software changes over the APS by performing a special reset (no other resets result in changeover). The system converts the customer data as necessary. Stations on the system cannot be used during the reset and subsequent system boot.
If the system cannot start the new APS, it switches back to the old APS with the original customer data and makes an entry in error memory. It is not possible to revert to the old APS in Release 3.0 and later.
After successful changeover, the system makes an entry in error memory and deletes the old APS. It takes roughly ten minutes to delete the APS. This does not interfere with switching traffic. The deleted block is available for another APS transfer. The system sends the entry in error memory to the service center.
Because the software is written to the FMC in compressed format during an APS transfer, you must decompress it again after the transfer.
Note on Hicom 150 E OfficePro: Following a hard restart, the seven-segment display remains set to "F" for 5 minutes during startup to allow the system to decompress the software.

Note to Teles Card Users (Not for U.S.)

A successful APS transfer using a Teles card is possible only when using a new Capi. You can download the new Capi from the Teles support server. The Capi required is Capi 1.1/2.0 Release 3.26.

Download and installation procedure:

Open the Teles support tool.
Click the ISDN.S0 button.
In the left window, select the TELES.CAP column.
In the right window, download the following files:
VxD-Capi 3.26 for Win3.1x and Win95 Install.hinweise (D,Info)
VxD-Capi 3.26 for Win3.1x and Win95 SW Part 1 (D,1.1MB, 2.5 min)
VxD-Capi 3.26 for Win3.1x and Win95 SW Part 2 (D, 2.8MB, 6.5 min)

12.2.2.8 Replacing the Flash Memory Card (not for OfficeOne/OfficeStart)

Insert the Flash Memory Card FMC into a PCMCIA slot in the central control board. You can remove the cards and replace them with another FMC after disconnecting the system from the power source.

Note the following: Always replace the FMC with another Siemens-approved flash memory card. Unapproved cards may have a different internal layout, which will influence access times and some features (such as CDB backup and APS transfer).

12.2.3 Board Replacement (Not Applicable to Hicom 150 E OfficeOne/Start)

In OfficePro only, you can remove and insert peripheral boards during operation. Missing or undetected boards do not change the database configuration.

In OfficeCom and OfficePoint, you need to disconnect the system from the power source before replacing boards.

Procedure
Step 
Action 
1.  
Disconnect the system power. Use lockout/tagout (LOTO) procedures. 
2.  
Remove one or more boards. 
3.  
Restart the system by reconnecting the power. 
4.  
Delete the slot in the user interface (29-4) 1. 
5.  
Disconnect the system power. Use lockout/tagout (LOTO) procedures. 
6.  
Insert the boards into free slots. 
7.  
Restart the system by reconnecting the power. 
8.  
Load the customer data from the system and set up the new boards (configure stations). 
9.  
Enter the new customer data. 

Loading an old CDB onto a system with an updated hardware configuration
Step 
Action 
1.  
Load the old CDB. 
2.  
System status. 
3.  
Switch to software configuration. 
4.  
Customize the boards to the hardware. 
5.  
Back up the current CDB. 
6.  
Load the CDB to the CS. 
The system software adds new boards according to the startup rules. The associated ports receive the default station numbers. Use Hicom Assistant E Office to resolve any numbering conflicts that may occur. In systems with a default numbering plan, the station numbers for the new board begin after the last station number already assigned and continue in ascending order.
If you replace a board with a board of the same type that has fewer ports, the system keeps the excess stations or trunks from the old board in the database when it activates the new board.
If you replace a board with a board of the same type that has more ports, the system activates the new board with the same number of ports as the old board. You can configure the additional ports manually.
If you replace a board with a board of a different type, the system does not activate the new board automatically. If you want to replace a board with a board of a different type or with a board of the same type that has more ports, you must delete the old board and correct its data in the CDB using Hicom Assistant E Office.

12.2.4 Replacing Telephones

You can connect and disconnect telephones during operation. The system retains the data for the disconnected telephones.
 
If you jumper stations on the MDFU/MDFU-E(such as with an ICCS network) without first entering the relocate code, the stations affected will go into operation with their default values when you reconnect them (refer to Section 7.12.12).  
In the case of optiset E telephones of different types (different numbers of programmable keys) the system retains the key layout of the old telephone and the disconnected add-on devices. You can use Hicom Assistant E Office to delete disconnected add-on devices and remove any keys that are no longer available on the telephones.

12.3 Error Detection, Signaling, and Correction

12.3.1 LED Signaling for Central Boards

12.3.1.1 Hicom 150 E OfficePro / OfficeCom / OfficePoint

12.3.3 Telephone Test

After the system has been started up and you have completed the country adaptation, you can perform a telephone test on each optiset E telephone by entering a code or selecting a service menu.

During the telephone test, the display, the LEDs, and the ringers on the telephone are activated. The telephone displays its station number, and the test ends automatically after a timeout.

Test Procedure on optiset E Telephones

All LEDs flash rapidly for approximately five seconds. All display characters are displayed on a dark background and a tone sounds. 

 
If the test does not produce the results described, the telephone may need an optiset E local power supply.  

If the date and time are not displayed on the screen after startup, the telephone or the cable path may be defective. Replace the telephone or test the cable path.

12.3.4 Line and Telephone Diagnosis

12.3.4.1 Trunk Status

The system software logs the current status of each line and trunk in a table. When the status changes, the system enters the new status with a time stamp. The time stamp indicates the date and time in one-second increments.

The system records the following states:

Idle
Incoming or outgoing call
Trunk-to-trunk connection (transit)
Line disabled (lockout switch or lockout in CDB)
Line or trunk failure

You can use Hicom Assistant E Office to display the table.

12.3.4.2 ISDN Trace

This feature enables you to monitor certain ISDN telephones or ISDN trunks in real time.

The system sends ISDN activities to Hicom Assistant E and places them in a trace file. Only the ISDN actions appear on the monitor, not the contents of the ISDN messages. At the end of the trace session, you can start the ISDN Trace Decoder Tool and convert the ISDN transmission to a readable format (English only).

12.3.4.3 Trace Enhancements in the System (Release 3.0 and later)

The trace enhancements include:

More flexibility in configuring error numbers for traces (trace stop), enabling you to determine which error number caused the trace to stop. You can also activate a trace stop by remote access.
If the customer detects an error (such as a double connection), you can stop a trace in progress manually from the telephone.
You can read out the trace data by remote access.
New ways to store extensive traces in the system. To do this, you must insert an SRAM card instead of the IMOD modem.

12.3.4.4 Call Trace

You can trace the activities, triggered by a phone call, of all telephones, lines, and other devices.

The restriction to a total of two traced objects no longer exists. This enables you to trace specific consultation calls, conference calls, as well as hunt group and LAN Bridge activities (the S0 interfaces are traced, not the LAN Bridge itself).

12.3.5 Displaying the Station Status

You can output the following status information for each station in online mode, using Hicom Assistant E. To call up the information for the desired station, enter the station number.

12.3.7 V.24 (RS232) and CSTA Trace

This feature enables you to monitor the interface to Plus Products connected to the Hicom 150 E Office system. The feature runs under Hicom Assistant E in the maintenance object, making it possible to use normal connection methods (V.24 (RS232), integrated modem, and digital modem).

You can trace the following data:

Status of the V.24 (RS232) lines (DTR, DSR, RTS, CTS) on the system board, enabling you to detect improperly connected and damaged cables. The Hicom Assistant E online help describes reference states of the interface lines for different products connected and, if applicable, the cables used.
You can trace the data flow on the lines (V.24 [RS232] and terminal adapter) in both directions and save it on disk. You can also define the beginning and end of the trace or the data set stored. The number of bytes exchanged and the time completed are displayed during the trace.
At the end of the trace, you can use an editor to display and thus check the stored data. Using the editor, you can also save the data to the hard disk or print it using a printer.

The failure of V.24 interfaces generates an entry in the error history file and triggers a remote signal. In Release 2.3 and later, reactivation of the interface is also recorded in the error history file and triggers a remote signal. The Check printer message on the screen disappears and is replaced by the normal display.

Error signaling indicates a deactivated DTR line at the first or second V.24 interface on the V.24 board. The system does not support a control adapter (printer pipeline mode).

12.3.8 Error Memory

An error memory area with five entries is provided for each line or trunk. When an error occurs, the system makes an entry with a time stamp. The entry shows the following:

No dial tone (analog boards)
Layer 1, 2, or 3 error
Board error

You can use Hicom Assistant E Office to convert error memory to a readable format for display.

12.3.9 Measuring the System-Wide Use of Features

Feature counters (such as caller list, call forwarding, or busy override) are incorporated into the system. You can use Hicom Assistant E Office to display the counts. Each time a feature is used, the system increments the counter for that feature.

12.3.10 Activated Features for Each Telephone

Certain activated features can be deactivated for individual telephones by entering a code (refer to Section 7.12.11 on Page 7-342). You can also use Hicom Assistant E Office to display, activate, and deactivate features.

12.3.11 Error Messages

12.3.11.1 Error Classification

Class A: Errors of interest to the customer. These errors can be corrected by the customer without support from the service department and are displayed at the intercept position. In the default configuration, class A errors are not displayed.
Class B: Errors of interest to service. The service department can correct these errors by replacing hardware or working with the telecommunications carrier to reconfigure the CDB. Class B errors include failures of boards, ports on boards, or trunks. The errors can be signaled to a service center.
Class C: Errors of interest to development. Specialists use these errors for diagnosis and problem analysis purposes. The errors are not signaled.

Class A Error Messages

PRINTER ALARM (such as printer out of paper) is currently the only Class A error message outside of the U.S.

For U.S. only: INVALID SPID (OfficeCom and OfficePoint) signals that the service profile identifier (SPID) for BRI ISDN is incorrect. Refer to Section 8.11.2, Examples for Configuring BRI Trunks (for U.S. Only), on page 8-28 for information on entering the SPID.

Class B Error Messages

The following tables describe appropriate actions in response to the error messages.

Recovery action includes the automatic error correction actions triggered by the software (such as board reload).
Technician action refers to the actions a technician must perform when the error message fails to disappear, possibly indicating a hardware fault.

Each error in error memory is programmed to initiate a specific corrective measure. The following software actions may occur:

Hard restart
Board reload
CDB backup reload
Port disabling
Power failure transfer (analog trunks)
None

A watchdog interrupts continuous loops.

12.3.12.2 Manual Error Correction Without Hicom Assistant E Office

Manual Restart and Reload for Hicom 150 E OfficePro

You can initiate the following actions by holding down the reset key on the CBMOD board for different lengths of time.

Press the reset key briefly to perform a hard system restart. The green LED (located just beneath the seven-segment display) lights up when you press the reset key.
When you hold down the key for more than 5 seconds, the green LED goes out and a reload is triggered. This restores the entire CDB to its default contents. All country- and customer-specific settings are lost.

Manual Restart and Reload for Hicom 150 E OfficeCom and OfficePoint

You can initiate the following actions by holding down the reset key on the CBPC board for different lengths of time.

Press the reset key briefly to perform a hard system reset. The green LED lights up when you press the reset key.
When you hold down the key for more than 5 seconds, the green LED goes out and a reload is triggered. This restores the entire CDB to its default contents. All country- and customer-specific settings are lost.

Disabling and Enabling Ports

You can disable ports on analog trunk boards in the outgoing direction and ports on digital trunk boards in both directions using a switch. In the case of subscriber line modules, you can disable only the entire board. Disabling a board prevents the trunk from being reseized after the current call has ended.

The Release external trunks feature enables you to interrupt an existing connection.

12.3.12.3 Error correction Using Hicom Assistant E Office

Restart

When Hicom Assistant E Office initiates a restart, the system software generates a special error. The restart takes place immediately.

Loading Boards

Hicom Assistant E Office supports selective resetting of boards with peripheral software. After the peripheral software is loaded, the system automatically downloads the data for the board.

Hicom Assistant E Office supports the loading of data onto boards. When data belonging to the (port- or card-oriented) download record changes, a download is initiated to all assigned boards.

Enabling and Disabling Ports

You can use Hicom Assistant E Office to disable boards and ports. Disabling the boards or ports does not interrupt existing connections. However, the ports cannot be reseized.

Hicom Assistant E Office cannot enable ports that were disabled by means of a switch.

Trunk Failure Transfer

Hicom Assistant E Office cannot be used to perform a power failure transfer to analog telephones.

12.4 Trunk Rolling (for U.S. Only)

Trunk rolling, also known as channel rolling, switches tip and ring on two adjacent central-office trunk lines in a Central Office Trunk Module (TMGL4 or TMGL8). It can be used to determine whether a problem originates in the trunk circuitry or in the central office (CO) equipment or wiring.

Procedure

Using Hicom Assistant E Office, select the boards and ports that you wish to switch over. Rolling active channels is not recommended, as communication is disrupted. After you have switched the channels, new allocations can help you determine where the problem is located:

If the problem stays on the same port after switchover, it is a problem within the trunk module.
If the problem persists on the new port, it is a problem in the connection to the CO or within the CO itself.

12.5 Automatic Error Signaling

12.5.1 Alarms on the System Telephone

Class A errors are displayed at the intercept position or output to the connected printer.

Example

PRINTER ALARM

The message can be cleared from the display using a procedure.
