DEFINITY Four-Wire Interface
The DEFINITY TN754B (any vintage) or TN754 (vintage 11 or higher)
circuit pack provides eight, four-wire digital station circuits. Two of
these wires are used for transmit, two are used for receive. Typically
the stations are wired to a block or to a patch panel. From the block
or patch panel the stations are wired to a modular jack. The jack can
connect to a short patch cord that connects to the MCU. The
following table shows the Avaya side of the block or patch panel
wiring.
