Just to be accurate, DS is digital service cross connect i.e. dsx1 panel, dsx3 panel, etc. Typically a ds0 cross connect is referred to as "ds0 wire frame" since it's muxed up to ds1's via DSX1 bays. A DSX panel is basically a piece of dumb equipment, sometimes fitted with led port tracers(useful)that you can configure in interconnect, one card, or cross connect, two card, modes for testing both sides, good add move, drop capability, etc. -M -- Martin Hannigan (c) 617-388-2663 VeriSign, Inc.

Finally, "dsx" does not stand for full duplex, as someone

DSx = DS0/DS1/DS3 (using "x" as wildcard). Not to be confused with uppercase "X".
