There are four ring patterns in common use:
Commands
Example: Sending
ATS70.0=1.3=1
to your modem enables the
recognition of ring types A and D only.
When a call comes in with a ring type A or D, the Courier V.Everything
modem will send the result code RING A or RING D, respectively. The
Courier V.Everything modem will ignore other ring types.
If S70 is set to 0 (the default) the Courier V.Everything modem detects
ring types A and B, sending the result code RING for either ring type. This
function is identical to that of other 3Com modems that do not support
distinctive ring.
If only one ring type is enabled, the Courier V.Everything modem will
recognise only the enabled ring type and ignore all others. It will send the
result code RING only when it detects the ring type that's enabled.
