DS3 / STS-1
Coaxial network interfaces are used for supporting high-speed electrical interfaces
such as DS3 and STS-1. The following discussion is relevant to both of these types of
network interfaces and multiplexers.
Coaxial cable network interfaces are delivered through a coaxial cable adaptor
installed on the rear side of the backplane of the system (labeled Adapter Module and
located at J34). These backplane-mounted coaxial adaptors interface exclusively with
the two multiplexer slots in a single system. See
Figure 10
.
Figure 10. The Coaxial Adaptor (P/N 1181004L1)
A single-interface coaxial adapter (1181004L1) provides a connection shared by the
two multiplexers for supporting 1:1 protection of the network interface electronics.
The coaxial adaptor is situated to allow routing of coaxial cables in any direction
through use of a coaxial elbow connector. Once two elbow connectors are installed to
the jacks on the side of the coaxial adaptor, the coaxial cables can be routed to the side,
top, or bottom of the system merely by rotating the elbow connector.
