DS1 Protocol Version a,b,c ??

[piken]

DS1 circuit pack has setting for Protocol Version a,b,c
What do a,b,c mean, a=custom? b=NI2, c=????

Also in my trunk group (ISDN/PRI) for the above
DS1 cp it has a Supplementary Service Protocol
of a=national, b=Q-sig

I've currently got this T1 (ISDN/PRI) headed to a piece of equipment and have everything is up and running.

The g3 is currently set as ....

DS1/Protocol Version = a
Trunk group/sup.svc.proto=a (national)

I get some strange errors on my ext. piece of equipment
and just want to make sure I've set everything set as best as possible. Errors, such information elements not reconized, some frame rejects and even an dropped D-channel now and then.

My equipment is capable of switchtype of
4ess,5ess,national,

I've changed back an forth between national/5ess and
both seem to work the same.

Another setting I have is "Network Specific Facility IE"
I've not set this, but maybe...
settings available are none,sdn,megacom,accunet

A little vague I know, just trying to match settings
on both peices of equipment to the same.

Thanks,

You may want to experiment with the Code Set on the trunk group form.

Thanks for your reply.

On my external peice of equipment I've been switching between
national and 5ess, both seem to work (fairly well).

Since the g3 is set to "a" I'll try 4ess on my equipment and
see if it works any better. All three must be very close.

The trunk group I think I'll leave set to national.
