We have a Nortel Norstar on 4.1 that has two (2) LS/DS trunk cards in it right now. We have 5 incoming lines from our local cable co. System is still running well, but we'd like to add Caller ID. CMS/CLASS info comes in from the Optimum, so it seems we should just be able to replace the LS/DS cards with versions that support CMS/CLASS. Is that all there is to it? Besides setting the phones to display the caller ID info, is there any programming to be done on the CICS itself? Also, how do I select which Caller ID supported cards to purchase? Here's what we have:
Tag on chassis: NNTM8455FPWR NT7B56FA-93
Software card: NNTM040E4M5F NT7B64MA CICS 4.1 S/W
LS/DS cards: 1: NNTM8455IB04 NT7B75GB-93
2: NNTM8455F0IZ NT7B75GB-93
LS/DS cards with caller ID that I've seen for sale: NT7B75
NT7B75AAAA
NT7B75AAAE
NT7B75AAAF
There are also cards that use NT5B..., but I expect that, since everything on our system starts with "NT7B..." I should stick with those.
Anywhere I can look that helps me choose which to use?
Thanks.
