Hello Everybody,
I've been managing an IPK-1 system for about 12 years.
( IPK-I, pk192, R4.2sw, T1 DID, COI, 48 PBX stations, 48 SLI stations, Elite Mail )

It's an old system but it's been completely reliable and the staff is satisfied with it.
But we need caller ID and that requires moving from T1 to PRI.

Reviewing the manuals and some older threads, especially by "doghart", I have come up with this work list
of which I would greatly appreciate any comments or suggestions:

1) Must use MIFM-U20 ETU with KMM chip installed to capture caller ID numbers.

2) Must use PRI-U20 ETU on "newer" IPK systems.

3) Must remove COI trunks, evidently their presence in the system is not compatible with PRI.

4) Remove T1 ETU and replace with PRI ETU ( 7-1)

5) Delete the T1 trunk group, Build new, PRI trunk group:
Telco must provide PRI D channel on time slot 24
span type: b8zs ( 1.13.xx)
trunk type: WINK (3-14)
trunk type DID (3-91)
assign DID ( 1-1-20,21,22)

6) Set up CAP keys on the stations and remove any CO appearance keys. ( 4-12 )
Currently we are using both CAP and CO on the same phones.

Questions:
Since I'm going from T1 to PRI will the master clock source change ? (can't see why it would ...)
If the DID configuration is already programmed can it be reused with the PRI trunks?
Is there any way to have a COI trunk group with a PRI ? (Currently I have dial-8 for CO trunks, dial-9 for T1.)

Thanks for reading this.

Sorry you didn't get a reply from someone who knows NEC, but it looks like you've got it figured out!

I don't think it's a case of no one answering as much as who would remember working on an IPK1 and putting PRI on one.

Hey not trying to be awkward but I recently was asked to reinstate SMDR on a 40 year old SDS and I was the only person willing to take this on! Yes I got it going but even I wouldn't attempt to get a PRI working on an IPK1!
