MGCP CLOCK SOURCE

Answered Question
Sep 24th, 2010

With H323 you configure clock sources via Network-clock....... and then the priority etc

network-clock-participate slot 1

network-clock-participate slot 2

network-clock-select 1 E1 1/0

network-clock-select 2 E1 2/0

If you have more then one E1 from the same carrier then you set - Or at least I do, or thought you should do, is to add on the following

Controller E1 1/0

Clock Source Line Primary -------1st Clock source

Controller E1 2/0

Clock Source Line-------------------2nd Clock source- used case E1 2/0 goes down

If you have other E1`s connecting to say PABX, then the others are internal to the GW so clock off 1/0 and then 2/0

Question

Now if you use MGCP - do you only set the Clock source on the Web page in CCM to be External for 1/0 and 2/0 and all other internal

How does the GW know the 1st choice clock source is 1/0 and the second 2/0 - is it due to

network-clock-participate slot 1

network-clock-participate slot 2

network-clock-select 1 E1 1/0

network-clock-select 2 E1 2/0

Do you need to add the commends again for MGCP

Controller E1 1/0

Clock Source Line Primary -------1st Clock source

Controller E1 2/0

Clock Source Line-------------------2nd Clock source- used case E1 2/0 goes down

thanks
