•
Use the no version to restore the default, which is to reject remote loopback requests.
•
See path ds1 remote-loopback.
path ds3 equipment loopback
•
Use to enable or disable the router’s ability to enter into a loopback initiated by a remote
device connected at the T3 layer.
NOTE: Remote loopback is available only on frame-based T3 interfaces configured to
use C-bit framing.
•
Specify one of the following loopback options:
•
customer —Enables the router to enter into loopback when it receives an appropriate
signal from the remote interface
•
network —Disables the router’s ability to enter into loopback when it receives an
appropriate signal from the remote interface; this is the default behavior
•
Examples
host1(config-controll)# path 12 ds3 2 equipment customer loopback
host1(config-controll)# path 12 ds3 2 equipment network loopback
•
Use the no version to restore the default behavior, which disables the router’s ability
to be placed in loopback by a remote device. Using the no version has the same effect
as issuing the command with the network keyword.
•
See path ds3 equipment loopback.
path ds3 loopback remote
•
Use to place a remote device, connected at the T3 layer, in loopback.
•
Specify the remote keyword to send a far end alarm code in the C-bit framing, as
defined in ANSI T1.404, to notify the remote end to activate or (when you use the no
version) deactivate the line loopback.
NOTE: Remote loopback is available only on frame-based T3 interfaces configured to
use C-bit framing.
•
Example
host1(config)# controller sonet 5/0
host1(config-controll)# path 12 ds3 1 loopback remote
•
Use the no version to turn off the loopback.
•
See path ds3 loopback.
path ds3 t1 loopback remote
