TSU 100/600. The Passthru option card should be
selected to provide DSX-1 access for PBXs, or other
equipment, that use a DSX-1 interface. When used with
a PBX, this interface permits the combination of voice
and data in a single T1 stream. The allocation of the
amount of bandwidth for the Passthru is selectable.

program. The internal menus for its configuration are a
part of the Passthru card and are automatically installed
when the Passthru is plugged into the unit.
