In the following example, a trunk clock from an 8 PRI CT1 feature card 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 feature card 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, the
Gateway(config)# dial-tdm-clock priority 3 free
Gateway(config)# exit
