Configuring Clock Recovery from BITS Port as an Input-Source
This section describes how to configure clock recovery from a BITS port as an input-source.
SUMMARY STEPS
1. configure terminal
2. network-clock synchronization automatic
3. network-clock synchronization ssm option option-id generation-id
4. network-clock input-source priority {external slot/card/port}
5. exit
DETAILED STEPS
Examples
The following example shows how to configure clock recovery from a BITS port for a Metronome SPA:
Router# configure terminal
Router(config)# network-clock syn
chronization automatic
Router(config)# network-clock syn
chronization ssm option 2 GEN1
Router(config)# network-clock inp
ut-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 syn
chronization automatic
Router(config)# network-clock syn
chronization ssm option 2 GEN
Router(config)# network-clock inp
ut-source 1 External R0 t1 esf
Router(config)# exit
The following example shows how to configure clock recovery with BITS as input-source on Cisco ASR
1002-X Series Aggregation Services Routers on a E1 Common Channel Signal Mode:
Router# configure terminal
Router(config)# network-clock syn
chronization automatic
Router(config)# network-clock syn
chronization ssm option 2 GEN
Router(config)# network-clock inp
ut-source 1 external r0 e1 cas crc4 120 linecode
Router(config)# exit
