Chapter 20 Connecting T3/E3 Network Modules
Connecting T3/E3 Network Modules to the Network
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.
