SSU-2000 Control Languages
Software embedded in the SSU-2000 hardware allows operators to query and
manage an SSU-2000 from a local or remote management terminal using one of
three control interfaces. These management agents allow operators to change
factory default settings, set or restore stored configuration settings, configure and
provision the SSU-2000 to meet the requirements of a unique environment, and
perform maintenance and troubleshooting.
The SSU-2000 supports three control interfaces. Each grants access to command
functions according to the security levels assigned to users. The control interfaces
are:
TL1 – The Transaction Language One (TL1) control language, perhaps the
dominant telecommunications industry ASCII command line interface, provides a
standard man-machine language. The TL1 language is defined in Bellcore
document TR-NWT-000831, Issue 3, Revision 1, December 1993.
ICS – The Interactive Command Set (ICS) control language also called the ASCII
command set, can be used to control the SSU-2000 from a terminal connected to
one of the SSU-2000 EIA-232 serial ports.
SNMP – The Simple Network Management Protocol (SNMP) protocol is based
on a client server query-response mode and is supported by Ethernet only.
There are six main executables (software versions) available for the SSU-2000 as
shown in Table B-2. This section provides information about the TL1 and ICS
control languages for all versions of software.
TL1 Command Interface, on page 266, defines the TL1 command and response
specifications.
– Table B-5 defines the TL1 retrieve commands, access identifier (aid) code,
description and use of the command function, and the response message
format for each.
– Table B-6 defines the TL1 set commands, access identifier (aid) code,
description and use of the command function, and the response message
format for each.
– Table B-7 defines other TL1 commands for logging onto and off the
SSU-2000, and for activating, disconnecting, and removing modules from
the SSU-2000.
Interactive Command Set, on page 315, defines the ICS commands, responses,
and events.
NTP Support, on page 382, describes NTP support functionality.
