Special Requirements For Placing Voice Or Data Calls On Touch-Tone Telephones 1 3 - AT&T MERLIN 3070 Administration Manual

SPECIAL REQUIREMENTS FOR PLACING VOICE OR DATA CALLS ON
TOUCH-TONE TELEPHONES
The MERLIN system is factory-set to be compatible with standard equipment used
at telephone company central offices. In the rare cases where an incompatibility ex-
ists, it can affect calls placed on Touch-Tone basic telephones connected to the
MERLIN system by a Standard Telephone Module (STM).
The MERLIN system is factory-set to wait 12 seconds between dialed digits to be
sure the user has entered all the digits of the number he or she wants to reach. Dur-
ing that time, the control unit also checks to be sure that this is an allowed call and
notes the telephone number for SMDR, if the system has that feature. When the time
is exceeded, any additional digits dialed aren't subject to call restrictions and don't
appear on SMDR reports.
If equipment incompatibility is affecting calls placed from basic telephones connected
to STMs in your system, shorten the dialing time-out as indicated below:
If data calls such as credit card authorizations give incorrect results, set the in-
terval at 4 or 8 seconds. In most cases, the 4-second setting works best.
If callers don't get through to the numbers they dialed, set the interval at 0
seconds (no delay).
NOTE: With a 0-second setting, basic telephones connected to the system by
STMs aren't subject to call restrictions, and the numbers people dial aren't shown
on the SMDR printout.
Follow the procedure below to set the dialing time-out. This involves changing the
delay interval for basic Touch-Tone telephones between dialing of the last digit and
connection with the outside line.
