E. Internal Calls
The internal call mode gives you the ability to create an “internal” call from one port of
the
FAXJACK to any other port. This allows the phones behind the FAXJACK to
selectively call any phone on another port and communicate with that phone. When the
two ports are connected together, the telephone line is disconnected so you don’t hear
busy signals, re-order tones or intercept messages while talking. It works like this:
When you go off hook on one of the ports, you are connected to dial tone from the
telephone line. You then dial “#1” through “#4” to ring another port (“#1” = Fax, “#2” =
Modem, “#3” = Phone 1 and “#4” = Phone 2). When the “#1” through “#4” is dialed, the
telephone line is disconnected and you begin to hear a simulated ringback tone (single
frequency ringback tones – 500 Hz – 2 seconds on, 4 seconds off), as the
FAXJACK
sends ringing to the appropriate port. Interrupted ringing is provided to the appropriate
port until the call is answered or the port that originated the call hangs up (no limit to the
number of rings). When the other port answers the call, the two ports are connected
together and can communicate. Once both phones hang up, the
FAXJACK returns to
idle.
F. Ring Limit and Rollover
How incoming calls and Ring No Answer (RNA) situations are handled depends on the
operational mode selected (automatic or manual), the type of incoming call (voice, fax,
modem, etc.) and how the call was sent to the port (transferred call, CNG detected, etc.).
The following charts show how calls are handled in both operational modes and all
situations.
