Cisco ASR 900 Series Configuration Guide

Configuring T1/E1 Parameters
To configure T1/E1 parameters:
enable
configure terminal
controller sdh 0/5/0
rate stm4
au-3 1
mode vc1x
tug-2 1 payload vc11
t1 1 loopback [local | network line]
t1 1 clock source [line | internal | recovered]
end
Loopback network payload is not supported. This is applicable for AU-4 Vc-1x and AU-3 Vc-1x modes.Note
If T1/E1 is enabled on a particular J/K/L/M, you can only configure overhead and threshold for that
J/K/L/M value.
Note
Verifying T1/E1 Parameters Configuration
Use show running-configuration command to verify T1/E1 parameters configuration:
#show running-configuration
controller SDH 0/4/0
rate STM1
no ais-shut
alarm-report all
clock source internal
overhead s1s0 0
aug mapping au-4
au-4 1
clock source internal
mode tug-3
tug-3 2
mode VC1x
tug-2 1 payload VC11
t1 1 loopback network line
t1 1 clock source line
SDH T3/E3 Configuration Parameters for SAToP
The following parameters affect SDH T3/E3 configuration:
• Clock — Specifies the clock source for T3 or E3 link.
• Loopback — Sets the T3 or E3 link in the loopback mode.
• CEM Group — Creates a circuit emulation (CEM) channel from one or more time slots of a T1 or E1
line of an NM-CEM-4TE1 network module.
• MDL — Sets the Maintenance Data Link. This is only supported for T3.
