Dtmf, Dial Tone Detection Setup - NEC SL2100 Programming Manual

ISSUE 2.0
Program 10 : System Configuration Setup
Level:
IN
Description
Use Program 10-09 : DTMF, Dial Tone Detection Setup to allocate the circuits on the CPU for either
DTMF receiving or dial tone detection.
Use the following as a guide when allocating DTMF receivers:
• In light traffic sites, allocate one DTMF receiver for every 8 devices that use them.
• In heavy traffic sites, allocate one DTMF receiver for every 3 devices that use them.

01 DTMF, Dial Tone Detection
Conditions
• CPU has 28 (Hybrid MLT Configuration) 24 (Digital MLT Configuration) Channel DSP resources
(receivers) only for basic CPU Board. EXIFB-C1 has additional 48 DSP resources which you can
add to CPU. Addition to that EXIFE also each has 32 DSP resource (receivers) only for expand
board.
• In case of 0 (= Common) is selected, and if 14-02-10 (Caller ID receive ability) is set to "Yes", DSP
resources are always allocated to analog trunk only, not for analog extension. If 14-02-10 is set to
"No", the DSP resources can be used for both analog trunk and analog extension commonly.
• You can define the figure for the resource number from 25 to 28, but you can't use the resources
due to the DSP specifications.
Feature Cross Reference
• Caller ID
• Central Office Calls, Placing
• Direct Inward Dialing (DID)
• Direct Inward System Access (DISA)
