$$$ Question about T1 CAS configuration?

titomontos · ‎02-15-2009

Hello,

When we want to choose the signaling at the T1 CAS we find that:

Router(config-controller)#ds0-group ds0-group-number timeslots

timeslot-list [service service-type] type {e&m-fgb | e&m-fgd | e&mimmediate-

start | fgd-eana | fgd-os | fxs-ground-start | fxs-loop-start

| none | r1-itu | r1-modified | r1-turkey}

My question here is : what is the meaning of fxs-loop-start and fxs-ground-start and fxo-loop-start and fxo-ground-start ?

Thanks....

Check this out:

is this mean that each channel at T1 will act as fxo or fxs with analog signaling ground start and loop start?

Yes. The A/B bits mimics hook status and ring current.

Thanks,

But there is a problem that fxo don't support DID also the fxs ( fxs must be FXS DID)?

What is the solution?

To use e&m for did, pri for did and ani.
