Aspila EX Hardware Man-
Direct Inward Dial (DID) (4/8DIOPU) PCB
(Figure 2-13)
The 4/8DIOPU PCB supports the analogue DID and single line telephone interface functions (such as
Off-Premise Extension). The function type is assigned in programming for each port. The circuit types,
however, should be grouped together. For example, with 3 DID circuits and 1 OPX circuit, they should
be grouped as DID, DID, DID and OPX and not DID, DID, OPX and DID.
The DIOPU PCB provides:
•
4 (4DIOPU) or 8 (8DIOPU) DID trunk circuits
•
4 (4DIOPU) or 8 (8DIOPU) DID trunk status LEDs
•
1 PCB status LED
•
1 run/block switch
The CN3 and CN5 connectors each provide connection to 4 analogue DID trunk ports,
which are
polarity sensitive (tip to tip, ring to ring)
. The OPX circuits, however, are not polarity sensitive. The
DIOPU requires one universal slot, with 16 maximum PCBs per system.
