SLT DTMF Receivers

LCR Versus Toll Restriction

Technical Manuals Online! - http://www.tech-man.com
When Single Line Telephones are connected to the
toll restriction is enabled, the DTMF receivers located in the system
monitors the call for a programmed time period. While the DTMF receiver
is monitoring the digits being dialed by a single line telephone, it is
considered busy and not available for monitoring another SLT
attempting to dial. When all DTMF receivers are busy, an SLT attempting
to go off-hook does not receive dial tone until a receiver is available.
The Triad-S System allows up to 5 DTMF receivers for monitoring SLT
dialing. If a system has heavy SLT usage, then toll restriction may inhibit
dialing by SLT stations.
Two (2) options are available to help alleviate this problem:
1. Shorten the SLT receiver timer [FLASH 01] [Button 12]. This frees up
DTMF receivers faster, but may not provide the desired toll restriction
for SLT stations.
2. Enable LCR and force LCR on SLT stations.
When the LCR database is set up, the 3-digit table allows entry of the
number of digits to expect. When a SLT dials the appropriate number of
digits, LCR releases the DTMF receiver and then be available for another
SLT call.
LCR is not an alternative to toll restriction nor is toll restriction an
alternate to LCR. They work best when programmed together. Toll
restriction specifies station dialing privileges, and LCR provides call
routing to appropriate lines.
LCR can enhance toll restriction by providing Store and Forward
operation to analyze digits being dialed before a trunk is seized. This
prevents users from by-passing toll restriction by taking advantage of the
time required for a central office line to provide dial tone. LCR is
recommended when toll restriction is enabled.
