Parameter: Accept Loopback Request
Default: Enable
Options: Enable
| Disable
Function: Enables or disables loop-up and loop-down code detection circuitry in the
link module. When this parameter is enabled, this interface accepts and
complies with requests to go into loopback mode from a far-end device.
Instructions: Enable or disable local loopback.
MIB Object ID: 1.3.6.1.4.1.18.3.4.9.3.1.10
Parameter: Loopback Configuration
Default: No Loopback
Options: No Loopback
| Payload Loopback | Line Loopback
Function: Setting this parameter forces the DS1 interface into loopback. The far-end
or intermediate equipment then performs diagnostics on the network
between that equipment and the DS1 interface. After testing, set this
parameter to No Loopback to return the interface to normal operation.
Instructions: Select the loopback configuration option.
MIB Object ID: 1.3.6.1.4.1.18.3.4.9.4.1.10
Payload Loopback The received signal at this interface is looped through the
device. Typically the received signal is looped back for
retransmission after it has passed through the device’s
framing function.
Line Loopback The received signal does not go through the framing
device (minimum penetration) but is looped back out.
