Only new to the world of clocking so be gentle :-)
I have inherited 4 x 3745 voice routers and am trying to understand why the network clocking is configured the way it is.
On one of the routers there is:
network-clock-participate slot 2
network-clock-select 1 E1 2/1 (this is to the PSTN)
network-clock-select 2 E1 2/0 (this is to our internal PABX)
This makes sense to me that we are taking the clocking from the external service provider.
The other 3 x 3745 routers also contain multiple E1 connections to the external PSTN and internal PABX but are configured to use the backplane for clocking.
i.e. no network-clock-participate for all slots.
From what i have read you are better off using the PSTN connection for clocking rather than the backplane.
There are no slip second errors at all and everything is working fine but I am wondering should i be changing the other three routers clocking sources as a best practice type exercise.
I also have to add a new E1 connection to an internal PABX on one of the routers using the backplane for clocking (with a connection to the PSTN) and am wondering if i leave it as is and use the no network-clock-participate slot for the new card.
Are all of the external PSTN connections going to the same carrier?
If so are they going to the same CO switch (to your knowledge?
I don't really understand why they would have you PABX as the second clock source - normally you would use a second line to the carrier and the PABX should be clocking from the router via a participate command
Does the PABX have another E1 directly to the carrier?
Are you getting this error “Installer User Interface Mode Not Supported. The installer cannot run in this UI mode. To specify the interface mode, use the -i command-line option, followed by the UI mode identifier. The value UI mode identifiers...
The below trick might come handy when you have to add a new node to a cluster but you don't have or is unsure of the security password for the publisher. This procedure has been around for ages.
1) Login into the CLI of the Publisher.
