did you do it like this:
(this is from Mroberts, not me)
Just sub PRI for T-1
did you go into maintenance, disable the card, then go into hardware, program the card, then re-enable the card? The following is the basic programming for a T-1
You must have either a Services Cartridge (slot 1) or a 6-port Combo card (slot 2) in order to provide clocking for the T-1. Only one of these is needed, even if you have two DTI cards.
The DTI card should go into Slot 4 first. If you have a second card it would go into Slot 3.
You must disable the card first, program the card for T1, then re-enable the card.
To Disable / Enable Card

Framing: ESF – Next (usually ESF, check with your Carrier
Internal CSU: ON – Next
{need to have either an external CSU or turn the internal one on. If customer needs to use some channels for data then they’ll need a CSU/DSU to split off channels before the 0X32. OR to split off data channels after 0X32 they’ll need a Nortel Data Interface (NDI) plus bandwidth allocation key codes}
DSX1 Bld: 000-100
Line Coding: B8ZS (usually B8ZS, check with the Carrier)
ClockSrc: Primary (second card would be secondary)
Re-enable the card in Maintenance now.
