CONNECTIONS
The 3192 HTU-C occupies one card slot in a CI Wescom 3192 Office Repeater Bay. Power and
alarm signals are provided to the card through the backplane of the shelf. DSX-1 and HDSL loop
signals are connected to the wire-wrap pins or mass termination shelf connectors corresponding
to the slot the unit occupies. Connections to the DSX pins are intended for intra-building wiring
only. Refer to
for 3192 HTU-C edge connector wiring.
The 3192 HTU-C is capable of span powering the HTU-R by applying simplex current to the
local loop. From 10 to 125 mA of current is coupled onto the HDSL span to power the HTU-R
and HRE when deployed.
