Greetings Avaya Techs.

I'll start by saying that I'm not all that familiar with the Definity but we have a few that we maintain as local presence for other vendors (cabling, move add, change type stuff).

One customer location is utilizing a Definity BCS and currently has a total of 4 T-1s connected to the TN2464 DS1 cards. Cards are labeled TN2464 DS1 Interface 24/32.

A new carrier, Telesphere, is courting the customer and proposing a solution which would interface back to the Definity as PRI. I'm assuming it's some type of IP/SIP delivery with PRI interface.

Questions are as follows:

1) Will the current TN2464 cards support PRI?
2) If so is there anything else needed (daughter boards, etc.)
3) If not what components will be required for PRI?
4) Anyone with experience with this carrier? Anything to be careful about other than I would guess analog fax/modem issues through the IP delivery (customer currently has 30-40 analog faxes working fine as DIDs on the T-1s through the PBX).

I seem to remember something about some of the Definity BCS cards (i.e. less expensive Avaya Business Partner product - may not be full featured, etc.)

Thanks in advance for any help and suggestions.

TN2464's were used for DS1 in legacy systems that were the B offer and also international. They should support ISDN PRI assuming the switch is licensed for it 'disp sys cust'. You shouldn't need anything else but a CSU. Fax and modem may not work.

what hardware platform? what Definity software version?

g3si, g3csi, g3r all handle PRI differently based on the hardware and software version.

g3r uses packet bus for isdn, g3 prologics is g3v6 and higher uses bus bridge for packet bus
g3si prior to g3v7 with packet bus used x.25 processor interface links and processor channels to make d-channels work. And as Dave mentioned, there is a RTU on display system customer-options and also qsig options, etc.
