I believe so, you probably want to "network-clock-select <pri x> e1 0/0/0" (set e1 0/0/0 as the "network clock" at pri x) then "network-clock-participate slot 0/1" The documentation says of the priority: " Selection priority for the clock source (1 is the highest priority). The clock with the highest priority is selected to drive the system time-division-multiplexing (TDM) clocks. When the higher-priority clock source fails, the next-higher-priority clock source is selected. Ranges are as follows: •Cisco 2600 series: 1 to 4 •Cisco 3660: 1 to 8 •Cisco 2800 series: 1 to 8" Check http://www.cisco.com/en/US/docs/ios/voice/command/reference/vr_n1.html#wp1031296 for more information.
