Making The Line Connections
When you are connecting to a loop start line board, make the line connections using customer-supplied modular
jacks (type 625A2-6), a customer-provided standard 4–conductor line cord and an equipment-provided
4–conductor line cord.
1. Install the industry-standard modular jacks at the DXP Plus location (
Line Jack A
) and at the PC attendant
position location (Line Jack B).
2. Wire the jacks straight-through (that is; wire T1 to T1, T2 to T2, R1 to R1, and R2 to R2) using twisted-pair
house wiring.
When you are connecting to a DID or Multipurpose line board, note that these boards provide line connections
through a 50-pin connector instead of an industry-standard modular jack. Make line connections to these boards
using a customer-supplied 50-pin connector block (66-type), a standard 25-pair cable, a customer-supplied
modular jack (type 625A2-6), and an equipment-provided 4–conductor line cord.
1. Install the 66-type 50-pin connector block at the DXP Plus location.
2. Install the industry-standard modular jack at the PC attendant position location (
Line Jack B
).
3. Use twisted-pair house wiring to connect the desired line pairs from the 50-pin connector block to the
customer-supplied modular jack at the PC attendant position location (
Line Jack B
).
