Note: The NA variant is designed according to the performance standard EIA/TIA 464C. The UK
Variant is designed in accordance with CTR21, but has design parameters favoring towards BS6305
and BS6450. The EU variant is designed in accordance with CTR21.

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).
