RJ21X Interface
The RJ21X network interface has a female 50-pin (25-pair) amphenol
connector, as shown in Figure 4–1.
To
connect
the RJ21X interface to the control unit, you must build a wiring
field between the RJ21X interface and the control unit using a 66-type block
(RJ21). This field converts the female amphenol connector to sets of four 1-
pair modular jacks.
