LS Trunk Signaling Protocols (3300 Universal ASU)
LS Trunk Parameters (3300 Universal ASU)
Music On Hold (3300 Universal ASU only)
Four physical ports are supported for Music on Hold (MOH) on the 3300 Universal ASU.
The MOH interface supports the following features:
•
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).
