You cannot install the line-side T1 card into the following card slot pairs:
Restricted:
If you must install the line-side T1 card into one of the restricted card slot
pairs, you can rewire your IPE module card slot to the I/O panel by installing
an additional NT8D81 cable from the line-side T1 card motherboard slot to
the I/O panel and re-arranging the three backplane connectors for the affected
card slots. This will permit the connection of the NT5D13AA Line-side T1
card carrier and maintenance external I/O cable at the IPE and CE/PE module
I/O panel connector for card slots that are otherwise restricted.
Alternatively, all line-side T1 card connections can be made at the main
distribution frame instead of connecting the NT5D13 Line-side T1 card
external I/O cable at the I/O panel. This eliminates these card slots
restrictions.

card slots available depend on what vintage level module you have.
