ACS-160 Series & STL-160 Series T1 Multiplexer Installation & Operation
Version 2.11, August 2011
5.2.3.2 Shelf-Level and Common Module Remote Access
Use LOCK and UNLOCK Commands
Each CM-5RB module can be remotely locked or unlocked using the LOCK/UNLOCK command pair.
When the module is locked, no setup changes can be made via the module's remote port. The
LOCK feature prevents accidental or unauthorized remote setup changes to ACS-160 Series
multiplexers that are permanently connected to dial-up phone lines or dedicated data lines. The
LOCK feature has no effect on local operation; setup changes, including locking and unlocking the
remote port, can always be done locally.
The LOCK command has this format:
<Address>:<Subaddress>:LOCK:;
Note that the parameter field is left blank.
The UNLOCK command has a slightly different format in that its parameter field must include the
password of the addressed multiplexer:
<Address>:<Subaddress>:UNLOCK:<Password>;
For example, assume that an ACS-165 multiplexer has been set up with an address of 8 and a
password of "BLUE." To unlock the remote port on its DI-A module, make setup changes, and then
relock the module, first issue this command sequence:
8:DI-A:UNLOCK:BLUE;
Then include one or more SET commands:
8:DI-A:LOCK:;
Change Password
In addition to an address, you can assign a password to each multiplexer. Once the multiplexer's
remote port(s) have been locked, you must know the password to make any remote setup
changes. You can assign the same password or different passwords to all of the multiplexers in a
given network, depending on your requirements.
Valid passwords consist of any string of letters and numbers up to 16 characters long. Like the
network address setting, the password is actually a CM-5RB parameter rather than a multiplexer
parameter. You would normally use a password on a one-per-multiplexer basis; that is, you can
assign the same password to both CM-5RB modules in a given ACS-165 drop and insert
multiplexer. However, this is not a requirement.
When shipped from the factory, each ACS-160 Series/STL-160 Series multiplexer has a "null"
password, which means that the parameter field of an UNLOCK command must be left blank to
unlock the remote port. To change the password of a given CM-5RB module, issue a SET
command in the format:
<Address>:<Subaddress>:SET:PASSWORD=xyz;
Here, "xyz" is the new password. For example, to set the password of a CM-5RB module to
"GREEN" in an ACS-163 terminal multiplexer with an address of 7, issue the command:
7:TERM:SET:PASSWORD=GREEN;
Or, to set the password of both CM-5RB modules to "BLUE" in an ACS-165 drop and insert
multiplexer with an address of 8, issue two commands (one to each remote port):
8:DI-A:SET:PASSWORD=BLUE;
8:DI-B:SET:PASSWORD=BLUE;
If the password is lost or forgotten, the multiplexer can still be unlocked locally using the Lock
function in the SIO Group.
