2-OPX Module
Installing the 2-OPX Module
The 2-OPX Module (P/N 92177A) provides two 2500 type analog circuits for connection to on-premise
2500 type single line devices (i.e., telephones, fax machines, modems, etc.) and to telco OL13B/C OPX cir-
cuits. It uses a single digital extension circuit for the power and signaling for both analog ports.
To install a 2-OPX Module (Figure 4-7):
1. Locate an 8-pin modular connector in a trunk block or station block.
Local codes may prevent you from using a connector on the trunk block for optional equipment.
2. For the connector chosen, cross-connect the associated wire pair from the trunk or station block to the
cross-connect block.
3. Install a modular jack for the 2 OPX Module within 6 feet of the module’s location.
4. Run one-pair 24 AWG station cable from the cross-connect block to the modular jack.
5. Terminate the station cable WHT/BLU - BLU/WHT leads to the RED and GRN lugs in the modular jack.
6. Install bridging clips as required.
7. Ground the 2-OPX Module by connecting a 14 AWG ground wire from the FG lug to a known earth ground.
8. Plug a line cord into the 2-OPX unit and the 2-OPX’s modular jack.
The DS1 LED on the 2-OPX Module lights steadily.
