Configuring Differential Clock Recovery Of T3 Interfaces For Satop; For Satop - Cisco ASR 900 Series Configuration Manual

Clock Recovery System for SAToP
Use the show running-config | section recovered-clock command to verify the recovery of adaptive clock
of T3 interfaces:
Router# show running-config | section recovered-clock
recovered-clock 0 0
clock recovered 1 adaptive cem 12 0

Configuring Differential Clock Recovery of T3 Interfaces for SAToP

• Before you start configuring DCR, RTP must be enabled on the CEM interface. The RTP is used to
• The minimum packet size of CEM pseudowires on the network that delivers robust clock recovery is
To configure differential clock recovery on T3 interface for SAToP in controller mode, use the following
commands:
enable
configure terminal
controller t3 0/4/12
cem-group 0 unframed
clock source recovered 1
exit
To configure RTP header under interface, use the following commands:
interface cem 0/4/12
cem 0
rtp-present
To configure differential clock recovery of T3 interface in global configuration mode, use the following
commands:
recovered-clock 0 1
clock recovered 1 differential cem 12 0
exit
Note The clock configuration on controller must be done before configuring the clock recovery on global
configuration mode.
