Determine Common Module Configuration
You can use a CONFIG? Command of the general form to determine the CM-5RB configuration
(setup):
<Address>:<Subaddress>:<CONFIG?>:;
For example, to determine the current setup of the DI-A module in an ACS-165 multiplexer with
an address of 9, issue this command:
9:DI-A:CONFIG?:;
The response to a CONFIG? command always contains this setup information about the addressed
CM-5RB module:
● Primary timing mode
● Fallback timing mode
● T1 framing format
● T1 line code
A typical response might be
* OK
PTIME = THRU (PRIMARY TIMING)
FTIME = INT (FALLBACK TIMING)
FRAMING = ESF
CODE = B8ZS;
In addition, the response may contain one or more of these messages:
PAYLD-LB = ON (PAYLOAD LOOPBACK ON)
(USING LOOP TIMING FOR PAYLOAD LOOPBACK)
LINE-LB = ON (LINE LOOPBACK ON)
EQPT-LB = ON (EQUIPMENT LOOPBACK ON)

There is an alarm condition at the remote end of the network.
The network payload loopback is active.
The network line loopback is active.
The master station detects a break in the network ring, which means a
break due to multiple master stations in the ring, a hardware failure at a
station in the ring, or a station mode set incorrectly.
The station cannot detect the frame boundaries on incoming traffic. This
feature can be caused by a hardware failure or incorrect station mode.
The local channel module data is conflicting with outgoing network
management traffic. For example, if the DS0 is set for time slot 12 and a
channel module is programmed to transmit data in time slot 12. Channel
module data has priority over network management traffic.
The backup common module has been activated, taking over the
functions of the primary common module.
