Signaling and Supervisory Tones

The standard range of programmed tones are composed of

•12 DTMF sets of tones

•1 set of tones that form part of the call progress tone plan

•1 test of 1004 Hz (digital milliwatt).

DTMF Signaling

Input Signaling: The system is capable of accepting and repeating the standard DTMF tones as specified in EIA/TIA 464-C.

Output Signaling: The Mitel Networks 3300 ICP meets the output signaling requirements as specified in EIA/TIA 464-C.

DTMF Output Signaling as specified by EIA/TIA 464-C

Time-Out Information

The system is capable of responding to, or providing, the following supervisory conditions:

•Switchhook flashes having a duration of between 160 ms and 1500 ms (as programmed) to activate Transfer/Consultation/Hold/Add-On features.

•Call transfer dial tone can be obtained by generating a calibrated flash. This method is recognized internationally and is generated in one of three ways:

-use a flash-hook for telephones connected to ONS circuits. Upper and lower detection thresholds for switchhook flash are programmable between 60 ms and 500 ms, and between 60 ms and 1500 ms respectively.

-use the calibrated flash button (for equipped telephones)
