SUMMARY STEPS
1.
Router(config)#
recovered-clock slot subslot
2.
Router(config-clock)#
clock master
DETAILED STEPS
Purpose
Command or Action
Specifies the slot and subslot of the CEoP SPA to recover the master clock signal
from. This is the SPA from which the TDM data will be sent. Enters the Clock
configuration mode.
Router(config)#
recovered-clock
slot subslot
Step 1
You must specify the 19.44MHz clock as the recovered clock to use as the
clock master.
Note
Specifies that the recovered clock is to be used as the master clock signal for
out-of-band clocking.
Router(config-clock)#
clock
master
Step 2
The router creates a virtual CEM interface for the master clock. Go to the following
procedures to configure an out-of-band channel to use for the master clock.
Configuring an Out-Of-Band Channel
To configure an out-of-band channel to use the master clock signal, perform the following steps:

which the master clock was recovered (Step
in the preceding task), and the
port number is always 24.
Creates a CEM attachment circuit for the master clock signal. Valid values for
circuit-id
are 0 to 63.
Router(config-if)#
cem circuit-id
Step 2
You can configure up to 64 CEM circuits under the master clock
interface.
