Connecting to the TL1 Port

Connecting to the TL1 Port
You can connect to the TSG-3800 and use the TL1 syntax with either COMM A,
COMM B, or the Ethernet port. If you use either COMM port, you must first log in as
a supervisor (level 3) or administrator (level 4) and change the port to the TL1
mode. See Setting the Operating
COMM A port remains in TL1 mode until you send the EXIT command or when you
send three consecutive ESC characters. The COMM B port stays in TL1 mode until
you change the mode again.
To connect to the TSG-3800 through the Ethernet port, use a terminal emulation
program. Enter the unit's IP address and specify port 4000. The port opens in TL1
mode and remains until you send the EXIT command (see Exit, on page 414) or you
terminate the session in the terminal emulation program. You can have one or two
Ethernet connections open at a time.
After you connect to the TSG-3800 in TL1 mode, log in using the ACT-USER
command, as described in
function is disabled in the TL1 mode. To log off without closing the connection, use
the CANC-USER command described in

Input Command Message Structure

The TL1 input command message structure is as follows:
cmd:<tid>:<aid>:<ctag>:<gb>:<pl>;
The colon (:) must be included in the command string, and the string is always
terminated with a semicolon (;). Unused fields are indicated by adjacent colons; if
an unused field is the last parameter in the parameter list (for example the General
Block or the Payload), the colon can be omitted. Descriptions of TL1 command
structure elements are shown in
All commands must contain the CMD, TID, and CTAG fields; the AID field is
optional. The GB field is not used; you must use double colons (::) immediately after
the CTAG field. You must terminate the command with a semicolon (;).
