Connecting Extensions

Each 16DSTU PCB connects 16 digital extensions. Each 8ASTU PCB connects 8 analog extensions. Each

4ASTU PCB connects 4 analog extensions.

To connect extensions (Figure 3-1):

Using Figure 2-12 Connecting Extensions on page 2-10 as a guide, insert the mod jacks into the appro-

priate connector on the PCB.

Install a modular jack for each extension within 6 feet of the telephone's location.

For each extension, run one-pair 24 AWG station cable from the cross-connect block to the modular jack.

Terminate the station cable WHT/BLU - BLU/WHT leads to the RED and GRN lugs in the modular jack.

Back at the main equipment location, run one pair of cross-connect wire between the pins on the B

block and cross-connect block to complete the connection.

Install bridging clips as required.
