2. Reflects the current for ringing a single station set (or DN telephone). There may be
as many as five ringers on each line.

Foreign and surge voltage protections

In-circuit protection against power line crosses or lightning is not provided on the Analog
Message Waiting line card. When the Analog line card is used to service off-premise
telephones, the NTAK92 Off-premise protection module must be used. Check local regulations
before providing such service.
