Enabling or Disabling Loopback Requests
By default, the MCT1 interface accepts requests to go into loopback mode from a
far-end device. During loopback, the port loops receive data back onto the T1
transmit path. The far-end or intermediate equipment then performs diagnostics
on the network between that equipment and this port.
You can disable detection of remote loop-up and loop-down code to prevent the
port from accepting loopback requests. With Accept Loopback Request enabled,
see “Setting the Loopback Configuration” to set the type of loopback.
Setting the Loopback Configuration
Setting a loopback option determines how the port responds to loop-up or
loop-down codes. Set the loopback configuration by specifying one of the
following options:
Payload loopback -- The received signal at this interface is looped through the
T1 framer before the received signal is looped back for retransmission. This
method maintains bit-sequence integrity for the information bits, but does not
maintain the integrity of frames or superframes.
Line loopback -- The received signal does not go through the framing device
but is looped back out. This method ensures minimum penetration.
No Loopback (the default) -- Deactivates any current loopback.
Setting the Source of Send Performance Messages
On DMCT1 net modules and QMCT1 or QMCT1 w/ DS0A link modules only,
you can specify the source of performance messages:
Customer Inst -- Indicates that the customer installation supplies the messages
Carrier -- Indicates that the carrier supplies the messages
