Configuring the Encryption Service Adapter
Step 1: Configure the T1 Channel Group
Task
Step 1
Specify a controller and enter controller configuration
mode.
Step 2
Specify the clock source for a link.
line specifies that the link uses the recovered clock
from the link and is the default setting. Generally, this
setting is most reliable.
internal specifies that the DS1 link uses the internal
clock.
loop-timed specifies that the T1 or E1 interface takes
the clock from the Rx (line) and uses it for Tx. This
setting decouples the controller clock from the
system-wide clock set with the network-clock-select
command.
Step 3
Select frame clock.
