The following new LAN functionalities (TCP/IP protocol family) are available:
![]() |
Release 2.2 SMR-J and later: SNMP, Hicom Assistant E Office (TCP), CDRC (TFTP server mode). |
![]() |
Release 3.0 and later: CSTA Phase II and Phase III (TCP), CDRC (TFTP client mode and TCP/IP client mode). |
Monitoring and control of the LAN components are provided by the Simple Network Management Protocol (SNMP).
As part of the TCP/IP protocol family, the Simple Network Management Protocol (SNMP) is an easy-to-use platform for performing management tasks in the Hicom 150 E Office system software. SNMP is used as a kind of management agent in Hicom 150 E Office, making it possible to monitor and administer LAN components (including Hicom 150 E Office itself) from a central location. This involves
![]() |
addressing Hicom 150 E Office via TCP/IP |
![]() |
allowing external management applications, such as HP Open View and IBM Tivoli, to access data in Hicom 150 E Office (using SNMP messages, such as GET, SET, TRAP) |
![]() |
implementing remote maintenance tasks (online port status, enabling and disabling ports, determining free ports) |
![]() |
transmitting service-related class B errors |
![]() |
visualizing the operating status of a Hicom 150 E Office system |
Management Information Bases (MIBs)
MIBs define the volume of data that can be administered via SNMP. They are data models that describe the network elements to be administered in a very specific form.
Hicom 150 E Office supports
![]() |
standard MIB II (according to the RFC1213 Internet standard), which provides Internet and router functions; |
![]() |
parts of the RMON 1/2 standard MIBs (RFC 1757, RFC 2021), which support |
![]() |
![]() |
Error history |
![]() |
![]() |
Trap configuration |
![]() |
![]() |
TFTP configuration |
![]() |
![]() |
General system information |
![]() |
a user-specific MIB that processes Hicom-specific statistic data (feature counters) and internal error messages (error history), covering the following areas: |
![]() |
![]() |
ControlGroup - status variables, general configuration, supplementary TFTP configuration data |
![]() |
![]() |
SystemInfoGroup - system configuration and status |
![]() |
![]() |
StatisticsGroup - statistic data on features |
![]() |
![]() |
ErrorHistoryGroup - Error history in Hicom format Error messages are forwarded in the form of SNMP traps via the LAN to a specific external management application. The SNMP traps form the error history data structure (time stamp, error class, error description). |
These components use the IP protocol according to OSI layer 3 and the UDP protocol according to layer 4. The SNMP protocol stack uses port numbers. The system supports the SNMP protocol version 1.0.
SNMP Messages
The following commands control SNMP messages for communication between the SNMP management agent (Hicom 150 E Office) and external applications:
![]() |
GET - retrieve data from agent |
![]() |
GET NEXT - read out data sequentially |
![]() |
SET - write data |
![]() |
TRAP - alarm messages issued by the SNMP agent |
There is an integrated mechanism for generating SNMP traps in the event of class B errors. The SNMP management agent evaluates the error messages. In the case of defined errors, it generates specific traps and transmits them in the form of IP data records to a configurable IP address (a total of five SNMP V1.0-compatible applications are supported, including HP Open View Network Node Manager).
Hicom 150 E Office uses the Transmission Control Protocol (TCP) for CSTA via IP, detecting and automatically correcting lost data packets over a permanent connection.
A total of three CSTA clients or applications can connect to Hicom 150 E Office simultaneously over the LAN, and thus can use CSTA over IP simultaneously. Restrictions may apply to applications that use certain services. For example, only one application at a time can start the message registration function.
|
For an external application to address Hicom 150 E Office, it must know the TCP port (7001) of the TCP/IP server implemented in Hicom 150 E Office as well as the IP address.
To set up calls, you need to administer the firewall in Hicom Assistant E Office (by entering the IP address of the CSTA client and enabling the CSTA application). By default, access is only via Hicom Assistant E Office (the first IP address in the firewall is 0.0.0.0). The system then requests the user name and password to authenticate the CSTA client. You can use Hicom Assistant E Office to draw up a list of five IP client addresses with access authorization.
Data packets sent from an application to Hicom 150 E Office -- that is, packets containing the Hicom IP address, TCP port 7001, and protocol type TCP -- are accepted for further processing.

Configuring the Feature Using Hicom Assistant E Office
Prerequisite: Hicom 150 E Office must already be registered on the LAN (see Section 13.6).
Configure the feature using Hicom Assistant E Office as follows:
In Hicom 150 E Office, you can start up the central call data output function only once, which means that it is available to only one application at a time. Three different modes exist to support the various requirements of the different applications.

Controlled by a programmable timer and a fixed threshold value determining the call data buffer capacity (around 80 percent of the call data buffer full), the TFTP client (Hicom 150 E Office) sends call data to the TFTP server (external application). If Hicom cannot set up a connection to the TFTP server, it addresses an alternative server. If this server is also unavailable, it outputs an SNMP trap or error message ("Unable to output data"). The system tries to set up another connection every 60 seconds. A call data buffer overflow causes an error message to to entered in the error history file.
Use Hicom Assistant E Office to configure the server and timer IP addresses.
|
When call data records accumulate, the TCP client (Hicom 150 E Office) sets up a TCP/IP connection to an external TCP server (external application) and transmits the data. The connection remains active continuously so that the system can send any further accumulated data, transmitting each data record separately.
Use Hicom Assistant E Office Office to configure the server's TCP/IP address (TCP port and IP address).
|
The external application (TFTP client) requests output of the call data records. To do this, the application must set up a connection and indicate the service (GET gez.txt), after which it receives all accumulated call data records. It releases the connection after the transfer.
Note: The IP address of the TFTP client must be entered in the firewall and the "call charges" application flag set.
The application's request for call data can be controlled automatically or using an SNMP trap (see Section 13.3). Hicom 150 E Office sends the SNMP trap ("data available") to the external application, generating the trap using a programmable threshold value determining the call data buffer capacity (0 to 80 percent of the call data buffer full). Use Hicom Assistant E Office to configure the threshold value.
Configuring the Feature Using Hicom Assistant E Office
Prerequisite: Hicom 150 E Office must already be registered on the LAN (see Section 13.7).
Configure the feature using Hicom Assistant E Office as follows:
![]() |
You cannot use Hicom Assistant T to configure this feature. If CDRC over IP (LAN) is set, you can use Hicom Assistant T only to switch to V.24 port, UP0/E port, Hicom Attendant P Office (PC AC) or "no output". |
All data transmitted must be in binary format.
