Page: 165 / 256

path ds3 loopback
•
Use to configure a loopback at the T3 layer.
•
Specify one of the following options:
•
local —Loops the data back toward the router; on supported line modules, also sends
an alarm indication signal (AIS) out toward the network.
•
network { line | payload }
•
Specify the line keyword to loop the data toward the network before the data
reaches the framer.
•
Specify the payload keyword to loop the data toward the network after the framer
has processed the data.
•
Example
host1(config-controll)# controller sonet 5/0
host1(config-controll)# path 12 ds3 1 loopback local
•
Use the no version to turn off the loopback.
•
See path ds3 loopback.
path ds3 t1 loopback
•
Use to configure a loopback at the T1 over T3 layer.
•
Specify one of the following options:
•
local —Loops the router output data back toward the router at the T1 framer; on
supported line modules, also sends an alarm indication signal (AIS) out toward the
network.
•
network { line | payload }
•
Specify the line keyword to loop the data back toward the network before the T1
framer and automatically set a local loopback at the HDLC controllers.
•
Specify the payload keyword to loop the payload data back toward the network
at the T1 framer and automatically set a local loopback at the HDLC controllers.
•
Example
host1(config-controll)# path 12 ds3 2 t1 14 loopback network line
•
Use the no version to clear the local loopback configuration.
•
See path ds3 t1 loopback.
Enabling Remote Loopback Testing
You can configure the router to request that compatible devices connected at the
following layers enter into a loopback:
• T1 over SONET/SDH VT layer
• T1 over T3 layer
