Distinctive Ring Patterns and Send_Commands

Distinctive ringing is a service provided by the local telephone company. Distinctive ring allows additional phone numbers to be assigned to a single phone line. Then, depending upon the number dialed, the ringing pattern is different.

The AXB-DTMF+ can identify up to four distinctive ring default patterns. Default time values for each pattern are shown in FIG. 1. A pattern consists of five parts. Depending on the ring pattern, a part is either high or low. The distinctive ring patterns shown illustrate the envelope of the incoming ring with respect to time. The four default patterns are:

!Default Pattern 1: 1 long ring lasting 2 seconds followed by 4 seconds of silence.

!Default Pattern 2: 2 rings, in a 2 second period, followed by 4 seconds of silence.

!Default Pattern 3: 2 short rings and 1 long ring, in a 2 second period, followed by 4 seconds of silence.

!Default Pattern 4: 1 short, 1 long, and 1 short ring, within a 2 second period, followed by 4 seconds of silence.

FIG. 1 DTMF+ distinctive ring default patterns and time values

Time values are in milliseconds (1000 ms equals 1 second). All 4 distinctive ring patterns are within a 2-second period from start to end time, for most applications. If you plan to change any of the distinctive ring patterns, it is advisable to stay within a 2 second time frame for each distinctive ring pattern.
