Slot and Carrier Restrictions

If rearrangement of circuit packs in the PBX is required to accommodate the
DEFINITY AUDIX system assembly, rearrange the packs as indicated on
Worksheet A-2, Port Slot Assignments , before proceeding.
If you are installing the DEFINITY AUDIX system in a System 75 XE or in a
single-carrier cabinet of a DEFINITY G1, G3i, G3r or G3s, slots 14 (or slots 13 in
an EPN control cabinet) should not be used for the DEFINITY AUDIX system
assembly.
See Appendix A, PBX Carrier Configuration Worksheets , of Planning for the
DEFINITY AUDIX System , 585-300-601, for detailed information on the
rearrangement of circuit packs and on slot restrictions.

DEFINITY AUDIX System Slots

The DEFINITY AUDIX system assembly requires five (four for G3vs) contiguous
port slots in the switch carrier. In this description, the five slots are referred to as
the 1st through the 5th slot , with the understanding that they can be any five
contiguous port slots. Place the assembly at least 6 slots away from the carrier
power supply if there are no circuit packs between the power supply and the
assembly. Place at least 3 slots away from carrier power supply if there is one or
more circuit packs between the assembly and the carrier power supply.
The slots are numbered from left to right on the front panel of the switch cabinet,
and from right to left on the rear panel as shown in Figure 2-2, Connecting the
Adaptor Cables Rear-Panel View. The five port slots are occupied by the
DEFINITY AUDIX system assembly as follows:
The 1st and 2nd slots are occupied by the DEFINITY AUDIX disk and tape
drives and do not connect to the DEFINITY AUDIX assembly.
The 3rd slot connects to the DEFINITY AUDIX system ALB.
The 4th slot connects to the DEFINITY AUDIX system MFB.
The 5th slot remains vacant to provide added clearance for components
on the MFB.
NOTE:
The G3vs switch has a single carrier with 10 slots.
For this switch, the DEFINITY AUDIX system assembly occupies only four
slots — the fifth (clearance) slot is not needed. The assembly must be
installed in slots 7-10 — the DEFINITY AUDIX system ALB occupies slot 9
and the MFB occupies slot 10.
