TRK MDF card (VB-44512): Trunk MDF Interface Card
The TRK MDF card provides a standard 25-pair connection at the DBS 576 Cabinet.
This interface board installs in one of five possible positions on either side of the
DBS 576 Cabinet and supports up to three trunk cards (LTRK/8, LGTRK/8 or
DIDTR/8). Since each of these trunk cards contains 8 extension ports, the TRK MDF
supports a maximum total of 24 trunks.
A standard 25-pair cable must be run from this interface board to the MDF.
