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):
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.
2. Install a modular jack for each extension within 6 feet of the telephone’s location.
3. For each extension, run one-pair 24 AWG station cable from the cross-connect block to the modular jack.
4. Terminate the station cable WHT/BLU - BLU/WHT leads to the RED and GRN lugs in the modular jack.
5. 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.
6. Install bridging clips as required.
