7.5.2 Multi-Device Connection (for U.S. Only)

Definition

The Hicom 150 E Office systems support ISDN data and video devices using an Industry standard ST interface. The ISDN terminal devices are connected to the system using the optiset E ISDN adapter or a port on an S0 interface card:

STLS4 for the OfficePoint and OfficeCom
STMD8 on the OfficePro

The ISDN devices are assigned a call number for internal dialing and an 11-digit Multiple Subscriber Number (MSN) for incoming DID applications.

Each ST port consists of two 64 Kbps channels. Two devices can be connected to the ISDN S0 optiset E ISDN adapter. Eight devices can be connected to an S0 port on an interface card. The devices connected on an S0 port share the 128 Kbps bandwidth for video and data calls.

Basic Rate Interface (BRI) Operation

In a BRI environment, each CO B channel is assigned a Special Profile Identifier (SPID) number and a Terminal Identifier (TID) for identification purposes from the Public Network. The SPID and TID received from the network provider must be associated with the call number assigned to the data or video equipment connected to the ST interface. If a system is equipped with three BRI trunks, the maximum number of ISDN data sessions is either three 128 Kbps sessions or six 64 Kbps sessions. Typically CACH (Call Appearance Call Handling) values or Phantom Directory numbers are required for Voice terminals only. In some COs, CACH values or Phantom Directory numbers can be required for the ST data devices as well.

Due to the complexity of BRI configuration, it is recommended that ST applications be limited to 128 Kbps. The call number for each ST port must be associated with a Public Network SPID. This means that the number of 64-Kbps channels that can be called up is limited to the number of Public Network SPIDs.

Refer to the Configuration Note for S0 Device Installation.
 
The STLS4 module is used also as a trunk interface in Europe. For subscriber applications, the receive and transmit leads must be reversed before connecting to the first device on the bus. This crossover is already performed in the optiset E ISDN adapter. 

Usually the ST device is connected to an ISDN NT-1 adapter and the SPID-TID numbers assigned by the CO are programmed in the device. However, since the ST device is located behind the switch on an ST bus, the Hicom 150 E Office provides SPID-TID identification control. Each ST channel used by the ST device requires a Call Number for internal dialing. An MSN number also is required to enable the ST device to communicate with the Hicom 150 E system.

The protocol should always be set to ATT NI-1 in the ST device. The Hicom 150 E Office performs all protocol conversions.

Primary Rate Interface (PRI) Operation

In a PRI or CorNet-N environment, SPIDs, TIDs and CACH values are not required. Internal SPID/TID entries called Multiple Subscribers Numbers (MSN) are used by the ST devices for call setup. DID numbers must be assigned to each channel that connects to an ST device.

The DID numbers can be assigned from the numbers received from the CO. The DID number can be from 1 to 11 digits. The DID numbers are required to set up incoming calls to the device.

Assign a call number to each No-Port station port used for the ST device. The call number can be from 1 to 6 digits. The call number does not need match the DID number.

An MSN number must be assigned to the ST device for each B-Channel required for the application. The MSN numbers act as SPIDs for the ST device. The MSN number can be from 7 to 14 digits. If the entry is 9 to 14 digits, the last 2 digits are used as the TID number. The last 2 digits should be 00 for B channel 1, and they should be 01 for B channel 2 on each ST interface used.

It is suggested that the MSN number consists of the DID number, followed by 5 zeros, followed by a 2-digit TID number.

7.5.3 Trunk Groups

Definition

The external trunks in the system can be combined into trunk groups by B channels. The order in which the trunk groups are seized can be linear (always the first free trunk) or circular (after the last trunk seized in the outgoing direction). An overflow trunk group can be configured for each of the trunk groups. If all the trunks in a trunk group are busy during a seizure attempt, the search for trunks continues in the overflow trunk group. The search is performed in the specified overflow trunk group only. If all the trunks are busy in this trunk group as well, no additional overflow attempts are made.

It is common practice to seize outgoing trunks starting with the highest numbered trunk, whereas incoming trunks will seize the lowest numbered trunks first. In the case of Key Systems, this reduces the risk of glare, or collision on loop start trunks.

A trunk group key can be assigned for these trunk groups. The key is for outgoing calls only. A maximum of 10 Trunk group keys can be configured on one station. Trunk group keys can appear on more than one optiset E telephone. These keys can only be installed on display telephones.

Calls placed on Trunk group Keys are subject to COS toll restriction levels and rules.

The system can monitor the line for the presence of dial tone. If not present, the system releases the trunk, and an error message is generated and recorded. The display user is presented with the text Not possible and reselect the Trunk group key to seize another trunk.

It is possible to turn off the detection and set fixed delay; contact your second-level Service group if this is recommended.

Operating the Feature

The user presses the trunk group key and receives a dial tone. The trunk number is displayed. If all trunks in the trunk group are busy, the corresponding LED will be lit. The LED also lights even if the trunk group has overflowed to another trunk group.

The user can put the call on Consultation Hold, transfer the call, place it in a Park location, or put it on station hold.

The trunk can be placed on hold. However, the user must use the Retrieve Line feature. When the user presses the Hold key, the display shows which line is being held; for example, Held on line: xyz. To retrieve the held call, the user must be in an idle state. The user presses the Program/Service key, scrolls to and selects Retrieve Line followed by the line number xyz.

Alternatively, the user can dial the default access code *63 followed by the held line number; the user is reconnected to the held party. A Feature key can also be programmed on a user's telephone to retrieve a held line.

The recall timer used is Time for parking and change to hold. The default value is 180 seconds.

7.5.4 Trunk Keys

Definition

On optiset E telephones, users can program trunk keys by B channel. This enables them to answer a call or seize a trunk by pressing the trunk key. The LED signals the trunk status.
LED 
Meaning 
Off 
Trunk is free 
Continuously lit 
Trunk is busy 
Flickering 
Incoming call or recall 
Flashing slowly 
Trunk is on hold 
Flashing rapidly 
Call waiting mode; call is at own station 

Users can use the trunk keys for the following features:

Call pickup
Retrieve trunk on exclusive hold
Retrieve trunk on common hold
Answer calls
Toggle between several different trunks

A Trunk key is used for receiving incoming trunk calls and placing outgoing calls on the selected trunks. A Trunk key represents an analog CO trunk appearance, a BRI link appearance, a T1 DS0 channel, or an analog E&M Tie line channel.
 
A Trunk key can not be programmed on the same station that is using Call Keys to manage the trunk group associated with the trunk appearance.  

A Trunk key can appear on more than one station. All stations with the appearance of the Trunk key can also ring on an incoming call, if they are programmed in a Call Group, otherwise they only have LED signalization.

A user can place a trunk appearance on Common Hold by pressing the Hold key and going on-hook. The trunk appearance will flash slowly at all other appearances of the Trunk key.

Calls placed on Trunk keys are subject to COS toll restriction levels and rules.

Trunk keys can be used in a Centrex environment. The system can cut through immediately to the Centrex CO to allow the user to hear if special tones, indicating Message Waiting. In this case, Dial Tone Detection must be turned off because the special CO tones are not recognized by the Hicom 150 E as dial tone.

Feature Interaction:

Call pickup: An incoming call ringing on a Trunk key can be picked from another station via the feature Call Pickup - Group or via Call Pickup - Directed.
Retrieve trunk on exclusive hold: A Trunk key is placed on exclusive hold at the station which put it on Hold by pressing another flashing Trunk key which results in a Toggle operation. To retrieve the held trunk, the user needs only to press the flashing key.
Retrieve trunk on common hold: Another user with the appearance of the same Trunk key, can retrieve a trunk call on Common Hold (Appearance flashing slowly) by pressing the flashing key.
Answer calls: Any user with the appearance of the trunk can answer an incoming call on the Trunk key by pressing the flickering Trunk key.
Toggle between several different trunks: If a user has an appearance of several Trunk keys on his or her telephone, the user can toggle between any of the trunks by pressing the desired Trunk key. The first trunk is placed on Consultation Hold at the station. Any subsequent depression of another Trunk key places the last call on Consultation Hold at that telephone. If the user goes on-hook at any point, the last held party is immediately recalled per the Consultation Hold procedure.
Call Forwarding: An incoming call appearing on a Trunk key can be forwarded by the station to another destination. If the forward destination does not have an appearance of the trunk, the user can handle the call via the dialog keys as a normal incoming call. If the forward station answers the call, the LED on all appearances of the Trunk key will be steadily lit.
If the station has forwarded the external calls to a voice mail system, the original destination's station number is forwarded to the voice mail system.

Operating the Feature

If the default station templates are in effect, this feature can only be used on display telephones.

Placing a call: The user presses an idle Trunk key. Simulated dial tone can be presented to the user until the trunk cuts through (See Routing Parameters -> Analog Trunk Seizure delay).
Receiving a call: An incoming call is signalled audibly and visually at the station. The display shows the trunk group name. If Caller ID is available, the user display indicates the calling party's Caller ID number. Calling party name is not available. The user presses the flickering key to answer the call.

7.5.5 Call Keys

Definition

Users can program up to 10 call keys (together with multiple subscriber numbers outside of the U.S. and MUSAP keys in the U.S.) on an optiset E telephone. These keys are used for incoming and outgoing calls. The call keys are assigned to trunks virtually; that is, the trunks are not permanently assigned to a specific key (like trunk group keys). When performing an outgoing external seizure, users press a call key to seize a trunk group. When users connect without a call key, an available call key is automatically seized, depending on the trunk group. With incoming calls, an available call key corresponding to the trunk group is also assigned.

The call keys should be viewed as temporary trunk keys that allow quick access to the following features:

Answering and signaling calls and recalls
Toggle
Cancel consultation hold
Pickup

Operating the Feature

If the default station templates are in effect, this feature can only be used on display telephones.

Answering and signaling initial calls and recalls: The Call key can also operate as a Loop key. That is, a user can have two or more Call keys on his or her telephone representing the same trunks. The first incoming call will be presented to the first idle Call key; the second call to the next idle Call key, and so on. The call can be transferred using the Consultation Hold function using a feature button or with the dialog keys. Unanswered calls or unretrieved parked calls recall the station on the Call key and can be answered again on the Call key (Common hold: still assigned to that Call key).
Toggle: If a user has an appearance of several Trunk keys on his or her telephone, the user can toggle between any of the Call keys by pressing the desired Call key. The first trunk is placed on Consultation Hold at the station. Any subsequent depression of another Call key places the last call on Consultation Hold at that telephone. If the user goes on-hook at any point, the last held party immediately recalls per the Consultation Hold procedure.
Pickup: An incoming call ringing on a Call key can be picked up from another station via the feature Call Pickup - Group or via Call Pickup - Directed.
Conversely, if a user with a Call key on the telephone, picks a trunk call from another station, the trunk appears on the Call key.
Placing a call: The user presses a Call key. The user is presented with simulated dial tone if LCR is in effect or, if not, CO dial tone.
Receiving a call: An incoming call is signalled audibly and visually at the station. The display will show the Trunk group name. If Caller ID is available, the user display will indicate the calling party's Caller ID number. Calling party name is not available. The user presses the flickering key to answer the call. The LED of the Call key remains lit.

7.5.6 Transit Traffic

Definition

Transit traffic refers to external voice calls that are handled by the telephone system in the incoming and outgoing directions. External connections can be set up to either the central office or to a networked system.

It is possible to handle transit traffic both manually and automatically over digital trunks and analog lines with a backward release criterion. Transit traffic can also be processed on analog trunks without a backward release criterion (loop start) by using timeout control followed by automatic release (maximum time is 42 minutes). Transit traffic is needed in the following situations:

Networked systems
Trunk-to-trunk connections (including DISA)
Transition from a private network to the public network and vice versa

Transit traffic is used in conjunction with the following features:

Call forwarding
Transfer
Callback (CorNet-N and QSig networks (Rel 2.0 or later); if supported on the trunk side, transit traffic can be used externally as well)
Message waiting for central voice mail servers in CorNet-N and QSig (not for U.S.) networks (Rel. 2.0 or later).
 
External access from a remote node is not possible over Hicom 150 E OfficeCom BRI trunks. Such calls are intercepted to the OfficeCom intercept position.  

Definition of Features Associated with Transit Traffic

Call forwarding: A trunk-to-trunk connection is possible using Call Forwarding - No Answer (only with a pseudo port) or Call Forwarding (CF) to an external destination. Care should be taken concerning the release capability of the trunks. Using LCR, an incoming call can also be forwarded (CF or CNA) to a CorNet-N link to a station in the remote node, to the Attendant in the remote node, to a voice mail system in the remote node, or rerouted to an external destination by the remote node. When calls from a Hicom 150 E are routed through a CorNet-N link to internal and external destinations, the CorNet-N channels must be split between these functions. In the case of a transfer to a remote voice mail system, the Hicom 150 E Office sends the originally called destination's station number to the voice mail to activate the proper answer message.
 
Always refer to the latest CorNet-N Configuration Note or the CorNet-N Sales Positioning Guide for the latest information.  
Transfer: It is possible for the user to transfer calls (screened and un-screened) to an external destination or to a remote node, via a CorNet-N link.
As of Release 1.0, version xxx, it is no longer necessary to perform a 2-step transfer procedure in the case of an unscreened transfer.
The transfer can also be initiated by a voice mail call processing feature or by an IVR which automatically transfers, unscreened, a call to an external or CorNet-N destination.
Callback: If Callback was activated by the user to a CorNet-N user in a remote node (a closed numbering scheme is required to activate this feature), the Callback will be activated the same as an internal Callback activation. (This feature is not available with connections to a ROLM 9005.)
Message waiting for central voice mail servers in CorNet-N networks: Message Waiting notification is possible from a remote voice mail system connected via CorNet-N links. In the case of PhoneMail, the SW version must be 6.3 or higher.

7.5.7 Translate Station Numbers to Names for System Speed Dialing

Definition

With system speed-dialing calls, the name of the destination programmed in the system speed-dialing facility is displayed after outgoing dialing instead of the speed-dialing number. If the station number of an incoming call corresponds to a station number in system speed dialing, the name of the caller appears on the display.

This feature only applies to systems with ISDN trunk connections or with Analog Caller ID on the OfficePoint and OfficeCom with Release 2.2.

The Hicom 150 E filters out the access code in the System Speed Dial table; however, the rest of the number must be an exact match to the incoming number for this feature to function.

Programming Hints

1. If using Hicom Assistant T, always enter the speed-dial number first, then enter the corresponding name. Hicom Assistant T does not allow a name to be entered for a specific index unless a number has been previously entered. Names can only be entered using the memory telephone or Hicom Assistant E Office.
2. Hicom Assistant T and Hicom Assistant E Office both check the first digit(s) of the speed-dial number you are programming against the default or current digits used in your database for external access codes. For example: entering the speed-dial number 71 510 555 1212, may be disallowed if the numbers 7 or 71 or 715 are not CO access codes.
