NFAS with 8 T1

I have 2 NFAS groups.

4 T1 in each.

Each group configured with primary and backup D-channel.

But I have few questions...

Only one controller T1 have clock source as primary... Is it enough for whole board? Or each nfas group should have it's own clock source?

For second nfas group I have only primary D channel up with protocol up ....

Should I have both up-up (line and protocol)? First group has it both up... I mean primary and secondary D-channel...

Re: NFAS with 8 T1

Usually there is only a single clock

source for a NAS; we have a techtip

written that may help understand some

of this, in general:

The line and line protocol should

be up for both primary and backup

members.
