SDI extension cable
The female 25-pin connector (P3) of the HomeOffice II Line Card (HLC)
Multi-I/O cable provides connectivity to the SDI port on the switch. If the
Multi-I/O cable is not long enough for P3 to reach the SDI port on the switch,
you must use the SDI Extension cable (NTDR59AA) to complete this
connection. You can obtain this cable from a Nortel Networks distributor, or you
can construct the cable, with a maximum length of approximately 14.5 meters
(48 feet), using the following pin-out table:.
Signal name

HLC Receive

Notes: The following factors may play a role in your individual situation:
1.
If you purchase this cable from Nortel Networks, request product number
NTDR59AA, order code A0748520.
2.
If you use the NTDR59AA cable, you will need a null modem adapter for
connectivity to an Option 11 system.
3.
If you create your own cable, you can build it to suit your exact needs.
