Configuring an Out-Of-Band Channel

To configure an out-of-band channel to use the master clock signal, perform the following steps:

2. Router(config-if)# cem circuit-id
3. Router(config-if-cem)# xconnect peer-router-id vcid encapsulation mpls
4. Router(config-if-cem-xconn)# end

Configuring the Circuit Emulation over Packet Shared Port Adapter
Purpose
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.
You must specify the 19.44MHz clock as the recovered clock to use as the
Note
clock master.
Specifies that the recovered clock is to be used as the master clock signal for
out-of-band clocking.
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.
Purpose
Selects the virtual CEM interface for the master clock and enters interface
configuration mode. The interface has the same slot and subslot as the SPA from
which the master clock was recovered (Step
port number is always 24.
Creates a CEM attachment circuit for the master clock signal. Valid values for
circuit-id are 0 to 63.
You can configure up to 64 CEM circuits under the master clock
