slot / subslot / port
Purpose
Exits pseudowire-class configuration mode.
Enters E1/T1 controller configuration mode.
Enters controller configuration mode and sets the clock source
on the interface to:
• 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.
Note By default, the clock source on the interface is set to
internal.
Assigns channels on the T1/E1 circuit to the circuit emulation
(CEM) channel.
Exits controller configuration.
Selects the CEM interface where the CEM circuit (group) is
located (where slot/subslot is the SPA slot and subslot and port
is the SPA port where the interface exists) and enters CEM
interface mode.
Defines a CEM channel.
