Connecting T3/E3 Network Modules to the Network Chapter 20 Connecting T3/E3 Network Modules Connecting T3/E3 Network Modules to the Network To connect a T3/E3 network module to the network, use a 75-ohm 728-A coaxial cable to connect the BNC connector on the network module to a networking device. (See Figure 20-2.) Warning This equipment contains a ring signal generator (ringer), which is a source of hazardous voltage. Do not touch the RJ-11 (phone) port wires (conductors), the conductors of a cable connected to the RJ-11 port, or the associated circuit-board when the ringer is active. The ringer is activated by an incoming call. Statement 1042 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 injury or damage your router. Statement 1031 Caution To minimize transient surges, the internal wiring should not be routed in the same conduit with power lines or external telephone lines.
