By issuing the network-clock-select command with appropriate parameters, you can define a particular port in a Cisco 7200 series router or a Cisco uBR7200 series to serve as the source of a PRS for the entire chassis or for other devices in the networking environment. This command enables you to designate a particular port in a Cisco 7200 series router or a Cisco uBR7200 series to serve as a “master clock”... - Page 21 Network Clock Distribution in a Cisco 7200 Series Router or a Cisco uBR7200 series When equipped with an ATM CES port adapter and appropriate software, any Cisco 7200 series router or a Cisco uBR7200 series can serve as a means for receiving and distributing a PRS to other devices in the network.
- Page 22 PRS. The default clock source is the local oscillator. But, in this case, this is not a problem because the traffic from the T1/E1 CBR ports is also disrupted. In the Cisco 7200 series router or the Cisco uBR7200 series, all T1/E1 traffic goes only on the ATM WAN uplink. When ATM 3/0 goes up, the PRS is automatically recovered.

Page 23: Clocking Modes For Ces Operations
Synchronous clocking mode requires a PRS and network clock synchronization services. When equipped with an ATM CES port adapter and appropriate software, any Cisco 7200 series router or Cisco uBR7200 series can serve as a means for synchronizing the flow of user CBR traffic through the network. -
Page 24: Synchronous Residual Time Stamp Clocking Mode
Although this clocking mode is the simplest and easiest to implement in an ATM network, it exhibits the poorest wander and jitter performance of all the available clocking modes. Therefore, Cisco does not recommend its use, except in instances where a PRS and network clock synchronization services are not available. -
Page 25: Summary Of Clocking Modes
Each end-to-end CES circuit exhibits delay characteristics, based on the following factors: The delay characteristics of the individual devices participating in the CES circuit. Each – network device contributes some increment of delay, reflecting that device’s unique electrical characteristics.

See Chapter 4, “Configuring the PA-A2 ATM CES Port Adapter,” more information on verifying a configured hard PVC. For an unstructured hard PVC, the CDV value for the circuit (including all hops) should not exceed a maximum allowable CDV value.
