Tip To save the gateway configuration, save it to NVRAM. Refer to the “Saving Configuration Changes” section on page 57.

Clocking Configuration Examples

In the following example, a BITS clock is set at priority 1:

Gateway(config)# dial-tdm-clock priority 1 external

Gateway(config)# exit

Gateway#

In the following example, a trunk clock from an 8 PRI CT1 DFC is set at priority 2 and uses slot 4 and ds1 port (controller) 6:

Gateway(config)# dial-tdm-clock priority 2 4/6

Gateway(config)# exit

In the following example, a trunk clock from a CT3 DFC is set at priority 2 and uses slot 1, ds3 port 0, and ds1 port 19:

Gateway(config)# dial-tdm-clock priority 2 1/0:19

Gateway(config)# exit

In the following example, free-running clock is set at priority 3:

Gateway(config)# dial-tdm-clock priority 3 free

Gateway(config)# exit

Verify

You can verify the system primary and backup clocks, the status of all trunk DFC controller clocks, and information about and the history of the last 20 TDM clock changes and the events that caused them.

•Verify your default system clocks and clock history by using the show tdm clocks command (this example is for T1/E1):

Gateway# show tdm clocks
