4331 Router Clocking Command help

[balukr]

One of our customer is replacing 2800 routers with 4331 routers. Existing 2800 has 2 PRI's in one of the routers when we tried to configure those in new 4331 router we had some issues with clocking commands. I did read this doc

http://www.cisco.com/c/en/us/support/docs/routers/4000-series-integrated-services-routers/118792-config-isr-00.html#anc7

but some of this commands are not working like they have it in the doc. I'm little confused/curious now so just want to check how clocking is configured on the 4331 routers and what would be the equivalent commands for the following in 4331 or do we need these or not?

2800 Config:

network-clock-participate wic 0
network-clock-participate wic 1
network-clock-select 1 T1 0/0/0
network-clock-select 2 T1 0/1/0

controller T1 0/0/0
 framing esf
 linecode b8zs
 cablelength long 0db
 pri-group timeslots 1-24 service mgcp
!
!
controller T1 0/1/0
 framing esf
 linecode b8zs
 cablelength long 0db
 pri-group timeslots 1-24 service mgcp

Some of the errors in 4331

VGW-4331-02(config)#

VGW-4331-02(config)#network-clock input-source 1 controller T1 0/1/0

% The clock source should be "line"

VGW-4331-02(config)#controller T1 0/1/0

VGW-4331-02(config-controller)#

VGW-4331-02(config)#network-clock synchronization participate 0/1 ?

  <cr>

VGW-4331-02(config)#network-clock synchronization participate 0/1

Slot 0 subslot 1 is already enabled for network clocking. Command Aborted.

VGW-4331-02(config)#

VGW-4331-02(config)#network-clock participate 0

G.781 based clock selection process

We are configuring 4331 with MGCP, IOS 15.4.3.S5, CUCM version is 10.5.2 SU2

Hi ,

here is a sample config and it looks like you already have clocking enabled on 0/1.

can you attached sh run and show network-clocks synchronization output ,if still doesn't work.

card type t1 0 2
!
isdn switch-type primary-ni
!
network-clock synchronization automatic
network-clock synchronization participate 0/2
!

!
controller T1 0/2/0
framing esf
linecode b8zs
clock source line primary
network-clock input-source 1 controller t1 0/2/0

Deepak, Thanks for the quick response. I'm not at that customer site now but will be there again this Friday to do the cut over if this is all we need then I will check and let you know if there are any issues. I will update later this week either way after the cut over.

Sounds good..good luck with cutover..!

As I promised here is the update, all of the above necessary commands are there by default and even when you have two T1s when you configure first one as primary for clocking second automatically sync's and knows the priority. Please make sure the DSP's are physically available properly on the MBD and modules.

Thanks.

Thank you for update...!
