I have a 3725 router configured as H.323 with a full PRI connecting to PSTN. The PRI is being under utilized so I have decided to reduce the channels to 11 B channels and a D channel. I've talked to my provider about applying the change and they said that the change is seamless and will not affect service at all but I am a little iffy about this.
Can someone please confirm the following for me ?
1. Does the change on my router and the provider's equipment need to be applied at the same time ?
2. Will there be any service down time ? I thought the pri-group timeslot has to match on both ends for the D channel to come up.
3. I'll be reducing the pri to 11 B channels and the provider has told me that the D channel will remain on the 24th channel. Do I just simply change the pri-group timeslot from 1-24 to 1-11 ?
The PRI is conneced to an NM-HDV with a VWIC-1MFT-T1.
thank you very much in advance !!
