Single Line Telephones, Analog 500/2500 Sets
Description
The system is compatible with 500 type (Dial Pulse) and 2500 type (DTMF) analog single line tele-
phones (SLTs). You can install single line telephones as On-Premise or Off-Premise extensions.
Single line telephone users can dial codes to access many of the features available to keyset users.
With Single Line Telephones, you can have your system simulate PBX type operation.
When installing single line telephones, you must have:
●
A port on an SLIU PCB for each single line telephone installed.
●
(If you have 2500 sets) At least one block reserved on the NTCPU for analog extension
DTMF reception.
CODEC Filter Data Setup Program Added
When
Program 82-07-01 : CODEC Filter Setup for Analog Station Ports
is set to "4 - Speci
Þ
ed
Data", the system will use the settings in
Program 82-09 : SLIU CODEC Filter Data Setup
.
These values should not be changed from their default settings unless directed by NEC’S Technical
Service department.
The side tone of the SLIU is adjusted using all 16 values, however, special software is required in
order to compute these values. The setting is not proportional to the gain level. To change these
values, contact NEC’s Technical Service department for assistance.
DTMF Dial Out Timer Added
Depending on your software version, Program 20-03-07 is available for DTMF dialing. When the
system is programmed to receive all digits before sending (Program 20-03-03=0), the system will
follow the timers in Program 20-03-04 and 23-03-07.
The timer in
Program 20-03-04 : System Options for Single Line Telephones - Dial Sending
Start Time for SLT or ARS
will reset when the user dials another digit.
The timer in
Program 23-03-07 : System Options for Single Line Telephones - Forced Dial
Sending Start Time
will not reset when a digit is dialed. The user must
Þ
nish dialing all the digits
before this timer expires.
