The following example shows how to configure clock recovery from a BITS port for a Metronome SPA:

Router# configure terminal

Router(config)# network-clock synchronization automatic

Router(config)# network-clock synchronization ssm option 2 GEN1

Router(config)# network-clock input-source 1 external 0/3/0 t1 esf

Router(config)# exit

The following example shows how to configure clock recovery from a BITS port for RP BITS on Cisco 
ASR 1000 Series Aggregation Services Routers with dual RP:

Router# configure terminal

Router(config)# network-clock synchronization automatic

Router(config)# network-clock synchronization ssm option 2 GEN

Router(config)# network-clock input-source 1 External R0 t1 esf 

Router(config)# exit

The following example shows how to configure clock recovery with BITS as the input source on the 
Cisco ASR 1002-X Series Aggregation Services Routers on the E1 Common Channel Signal mode:

Router# configure terminal

Router(config)# network-clock synchronization automatic

Router(config)# network-clock synchronization ssm option 2 GEN

Router(config)# network-clock input-source 1 external r0 e1 cas crc4 120 linecode

Router(config)# exit

This section describes how to configure clock recovery from a BITS port as an output-source.

 slot/card/port}

Router(config)# network-clock 

Router(config)# network-clock 

Router(config)# network-clock 

Enables clock recovery from a BITS port.

Routers with dual hardware support, such as the 
Cisco ASR 1006 Router, can have two RP ports, 
wherein one RP is active and the other is 
standby. Both the active and standby RP BITS 
ports can be configured as output sources.

Router(config)# exit

Exits the global configuration mode.
