RJ-21 Port Connector and Cabling Specifications

Warning If the symbol of suitability with an overlaid cross appears above a port, you must not connect the port to a public network that follows the European Union standards. Connecting the port to this type of public network can cause severe personal injury or can damage the unit. Statement 1031

Caution Do not connect the WS-SVC-CMM-24 FXS port adapter directly to a voicemail server, IVR application, or fax server if the servers have unused wiring pairs with voltage on them. We recommend that you connect the 25-pair cables to punch-down blocks and cross connect to the voicemail, IVR, or fax servers. If you do not use punch-down blocks and cross connects to the WS-SVC-CMM-24 FXS port adapter, you could damage the port adapter. For example, the FLT-8 card for the Octel 250 uses every other pair for its voice ports. The unused pairs have +36 VDC across ring-to-ground in an on-hook condition, and this high voltage has been known to damage the WS-SVC-CMM-24 FXS port adapter.

Use a standard RJ-21 Category 5 telco connector and cable to connect to the RJ-21 connector. Two types of RJ-21 connectors are shown in Figure 15 and Figure 16. A pinout for the module’s RJ-21 connector is provided in Table 7.
