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 an RJ-11
modular plug (connector) which 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, etc.). Figure 3-9 illustrates the signals passed
through modular cables when connected to a CMX-24 cluster multi-
plexer.
