Music On Hold (Universal ASU only)

The MOH interface provides four physical ports for Music on Hold. However, only one port (of ports 1 or
2) is supported through system software.
Each MOH port provides:
600 ohm input impedance
•
Signal level overload protection as mandated by FCC part 68 on encoded analog content
•
Dry Tip/Ring interface (no battery)
•
Always active input (no external control required or provided).
•
The connection requires a cable with a 3.5 mm mono jack on one end and an 8-pin modular jack (RJ-45)
on the other end. The RJ-45 plugs into the Music On Hold port on the rear panel of the Universal ASU;
the 3.5 mm mono jack plugs into the output connector on the music source (for example, radio). If you
use a stereo jack, short the left and right channels of the jack.
