1.2.2 The “Handshaking/Control Signal Trans-
ceiver” Block
The “Handshaking/Control Signal Transceiver” Block
contains receivers RX4 and RX5, transmitters TX4
and TX5, and a transceiver TR6 which is composed
of TX6 and RX6. Each of these devices may be con-
figured to support the “Electrical Interface” require-
ments per ITU-T V.11 (EIA-422), ITU-T V.10 (EIA-
423), or ITU-T V.28 (EIA-232). The RX4-TX4 pair is
dedicated for the “RTS” (Request to Send) and “CTS”
(Clear-to-Send) signals while RX5-TX5 are intended
to support the “DTR” (Data Terminal Ready) and the
“DSR” (Data Set Ready) signals. Transceiver TR6
supports the “DCD” (Data Carrier Detect) signal.
