Cisco ASR 900 Series

PurposeCommand or Action
Exits pseudowire-class configuration mode.exit
Example:
Router(config-pw-class)# exit
Step 11
Enters E1/T1 controller configuration mode.
controller {e1 | t1} slot / subslot / port
Example:
Router(config)# controller e1 0/1/8
Step 12
Enters controller configuration mode and sets the clock source
on the interface to:
clock source {internal | line | loop}
Example:
Router(config-controller)# clock source
internal
Step 13
• Internal–The system clock selection process does not select
clock source as the interface but it uses the system clock
for TX.
• Line–The system clock selection process selects the clock
source line as the interface and uses the system clock for
TX.
• Loop–The system clock selection process selects the clock
source line as the interface. For TX clock the interface uses
the clock source received on the same interface.
By default, the clock source on the interface is set to
internal.
Note
Assigns channels on the T1/E1 circuit to the circuit emulation
(CEM) channel.
cem-group number timeslots number
Example:
Router(config-controller)# cem-group 5
timeslots 12
Step 14
Exits controller configuration.exit
Example:
Router(config-controller)# exit
Step 15
Selects the CEM interface where the CEM circuit (group) is
located (where slot/subslot is the SPA slot and subslot and port
interface cem slot / subslot / port
Example:
Router(config)# interface cem 0/2/8
Step 16
is the SPA port where the interface exists) and enters CEM
interface mode.
Defines a CEM channel.
cem group-number
Example:
Router(config-if-cem)# cem 5
