TL1 Command Interface
Telcordia Technologies (formerly Bellcore) specifies the TL1 command interface for
use as a standard man-machine language for controlling telecommunications
network elements. TL1 provides command sets to support all operation,
administration, maintenance, and provisioning tasks required to maintain and
control an SSU-2000e. These tasks include configuring and provisioning security,
monitoring system performance, configuring hardware, locating and handling faults,
and performing equipment diagnosis and testing.
To set up an SSU-2000e port for TL1 communications:
1. Log on to one of the SSU-2000e EIA-232 serial ports using a Supervisor-level (or
higher) user name and password.
2. Set port A, B, or L to TL1 mode. For example, to set the local port (COML) to TL1
mode, at the system prompt, type:
COMM L MODE TL1
then press
Enter
The communications mode settings for the COMM A and COMM B ports (located
on the connection panel) are stored in non-volatile RAM, and remain in effect
even after restarting the SSU-2000e.
The communications mode settings for the COMM L (local) port (located on the
Communications module) always default to ASCII (ICS) mode on startup.
3. To close the serial port for TL1 communications, type
EXIT::::0;
or send three
ESC
ape characters from the management terminal. This logs you out and
returns the port to the default communications mode.
When you connect to the SSU-2000e via Ethernet port 2000 (decimal) using a
Telnet-type application, the session opens in TL1 mode. Up to four sessions (users)
can be connected to port 2000 at one time. Once you are connected, you must log
in using the ACT-USER command with a user name and password (if security is
active on the unit).
To log off the user and exit from an Ethernet session, type
CANC-USER:::0;
.
Another user can then open a new session by using the ACT-USER command.
To log off the user, exit from an Ethernet session, and close the Ethernet connection
to port 2000, type
EXIT:::0;
. The next user must first connect to port 2000 and
then log in using the ACT-USER command.
Note:
To communicate with the SSU-2000e, you must first connect a
terminal to one of the three EIA-232-C serial communication ports and
then provision the Ethernet port. Then you can communicate with the
SSU-2000e using an Ethernet telnet session.
