Channel Bank

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:

    This is what the Church is said to want, not party men, but sensible, temperate, sober, well-judging persons, to guide it through the channel of no-meaning, between the Scylla and Charybdis of Aye and no.
    Cardinal John Henry Newman (1801–1890)

    O Gold! I still prefer thee unto paper,
    Which makes bank credit like a bark of vapour.
