In telecommunications, a channel bank is a device that performs multiplexing or demultiplexing ("demux") of a group of communications channels, such as analog or digital telephone lines, into one channel of higher bandwidth or higher digital bit rate, such as a DS-1 (T1) circuit.
A channel bank may be located in a telephone exchange, or in an enterprise's telephone closet or enclosure where it "breaks out" individual telephone lines from a high-capacity telephone trunk line connected to the central telephone office, or the enterprise's PBX system.
A working example in the finance industry is to provide several automatic ringdown (ARD) lines over a single T-1.
Famous quotes containing the words channel and/or bank:
“Children belong in families, which, ideally, serve as a sanctuary and a cushion from the world at large. Parents belong to society and are a part of that greater world. Sometimes parents are a channel to the larger society, sometimes they are a shield from it. Ideally they act as filters, guiding their children and teaching them to avoid the tempting trash.”
—Louise Hart (20th century)
“What’s breaking into a bank compared with founding a bank?”
—Bertolt Brecht (1898–1956)
