Connecting the 7405D channels
Avaya Definity G1, G2, G3 and Prologix (PIC-A)
7.0 HARDWARE INSTALLATION
7.1 CONNECTING THE DIGITAL CHANNELS
Each PIC-A supports 12 voice ports. The first port uses the first two pairs
of the cable (pins 1, 26; 2, 27); the second port uses the next two pairs of
the cable (pins 3, 28; 4, 29), etc. Make sure that cable pairs are not
"rolled" when connected from MDF to the Octel system: i.e. Transmit-Tip
and Transmit-Ring (TXT and TXR) are connected on the first pair assigned
to the port, and Receive-Tip and Receive-Ring (RXT and RXR) are
connected on the second pair for that port. Only the first 24 pairs are used.
Also, make sure that when connecting voice ports from the PBX to the
Octel 350, do not use unprotected outside wiring, as PIC-A's do not use
surge protection hardware.
Physically connect the lines used for the voice path between the
switch and the Octel 350. The voice lines are connected to the
switch using customer-supplied male-amphenol cables which
terminate on the main backplane on the Octel frames. See Figures 5
and 6.
