Modular Cables
RJ-11 modular cable is the flat cable used for wiring telephones inside
of buildings. The cable is terminated at each end with a RJ-11
modular plug (connector). This plug is inserted into the modular jack
of an appropriate wiring module. Standard modular cables, available
from Equinox or wiring distributors, are reversing. That is, the pins
are reversed on each end so that pin 1 on one end is connected to pin 6
on the opposite end (pin 2 is connected to pin 5, etc). Figure 3-10
illustrates the signals passed through modular cables when connected
to a port using the Equinox part number 210016 modular splitter.
Modular Adaptors
Modular adaptors (see Figure 3-11) convert modular jacks to DB-25
or DB-9 connectors. The following list describes the modular adaptors
available from Equinox. This list may be used to determine the
correct modular wiring accessories required for system installation.
