Cables, Connectors, and Ports
Table 2-1
shows the cables, connectors, and ports required to install the RPSD
system. This table includes optional connections as well as the basic
configuration.
Installing the RPSD Lock
Install the RPSD Lock between the central office line that is reserved as the
remote maintenance and administration channel and the communications
system modem (see
Figure 2-1
). The central office line is usually in a
punch-block configuration but may be set up in a number of different ways,
including an RJ11 adapter or a multiple-pair gang plug. If one is not already
present, install an RJ11 port on the central office line to facilitate installation of the
RPSD Lock and also to make subsequent service easier. Label all connections.
