Appendix I - Testing Your MMH 2834
message. Hitting any key also aborts the $ command.
The following is an example of this command:
ATDT1028806127853500 $123456789
(access/phone number) (credit card number)
Quiet Answer The @ command causes the MMH2834 to wait before processing
the next symbol in the dialing string. The wait is for one or more
ringbacks followed by 5 seconds of silence.
@ If 45 seconds pass before the rings and silence, a NO ANSWER
(R) result code is processed. The @ command is used for
accessing a system that does not provide a dial tone.
For example, ATDT5551212@6313550 causes the MMH2834
to dial the first number (555-1212) and wait for 45 seconds for at
least one ringback and 5 seconds of silence. If a busy signal is
detected, the MMH2834 hangs up and generates a BUSY result
code. If it does not detect 5 seconds of silence, a NO ANSWER
result code is generated after hanging up. If 5 seconds of silence
is detected, the second number (631-3550) is then dialed.
