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 except that we need caller ID and our Telco says that requires a PRI interface.
When I converted the system from CO lines to T1, about 8 years ago, I had a tech help me with the setup and warn me of any potential problems, which there were none.
I get the suspicion that PRI is not going to be as straight-forward so I'm looking for advice.
Reviewing the manuals and some older threads 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. The older PRI-U10 won't work.
3) Must remove all 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.
What else am I missing or mistaken on ?
Thank you for reading this post...
