Note
The 2-wire iDSL modem lines are polarity insensitive so you only
need to match the correct pair of wires to the correct pair of terminals
on the punch-down block.
3. Select and attach the appropriate twisted pair from each remote (CPE) iDSL modem on punch-down
blocks for connection to the chosen iDSL port in the 3196RC.
Connecting the BITS clock
The ForeFront system can accept and synchronize with an external reference clock signal provided by a build-
ing integrated timing system (BITS) residing at the installation site. The BITS clock signal is specified by ITU-
T Recommendation G.703 as a balanced, polarity-insensitive, 64kbps signal with a maximum voltage
of 2.2 Vpp.
