System Type vs. Wireline Circuit

Table 11 shows which of the four (4) wireline circuits to use for various sys-
tem types.
Stations equipped with a 4–wire Wireline Interface can support a single 4–
wire or a single 2–wire telephone line connection.
Stations equipped with an 8–wire Wireline Interface can for example sup-
port a two 4–wire or a single 2–wire telephone line connection.

i) For 4–wire systems, Line 1 is transmit audio (landline to station),
and Line 2 is receive audio (station to landline). For 2–wire systems,
Line 2 is transmit and receive audio.
ii) A CPI is a Console Priority Interface.; used in Trunking systems.
A CIT is a Central Interconnect Terminal; used in Trunking systems.
iii) Transmit audio with respect to consoles, comparators, CIT, and
DVM modems are outputs.
Transmit audio with respect to stations is an input.
iv) Receive audio with respect to consoles, comparators, CIT, and DVM
modems are inputs.
Receive audio with respect to stations is an output.
