Configuring Clocking Signals

By default, the synchronous interface operates with an external clock source at

64102 b/s. You can configure the source and speed of synchronous timing signals

by:

• Setting the Clock Source

• Setting the Internal Clock Speed

• Setting the External Clock Speed

Setting the Clock Source

The Clock Source parameter specifies whether the origin of the synchronous

timing signals are supplied by the router (Internal) or by a network device

(External).

With this parameter set to Internal, the router supplies the required timing signals.

If you set the clock to Internal, set the internal clock speed as described in the next

section.

With this parameter set to External (the default), an external network device

supplies the required timing signals. In most cases, this parameter should be set to

External. See “Setting the External Clock Speed” on page 2-11

Set the Clock Source parameter to Internal or External for the interface.

Using the BCC

clock-source

variable

For example:

sync/4/1# clock-source internal

sync/4/1# clock-source external

Using Site Manager

See the Clock Source parameter on page A-58 for information.
