Advanced Emulation Software Module (TLE-ADV)
The TLE Advanced Emulation Module provides 16 different configuration settings, the
ability to enable Caller ID after every ring and the ability to disable DTMF detection. In
addition, this module provides emulation of impairments, metering tones, and the ability to
measure signal level. This module is sold separately. See the Ordering Information
section of this manual for details.
Note: This upgrade requires a software key that is generated by Teltone when the user supplies
the TLE Unit ID and the TLE-ADV serial number to Teltone. The instructions are included
on the Application Guide with the upgrade module.
Rotary Dial Only
Rotary Dial Only operation is to be used when there is a need to accept only rotary dialed
(a.k.a. pulse dial) numbers. DTMF tones are still decoded during the first 30 seconds after
power up. This feature is programmed on the Miscellaneous screen.
Caller ID After Every Ring
Caller ID After Every Ring is a feature that will send the FSK sequence after every
Power Ring Cycle. This feature is programmed on the Caller ID screen (TLE-ADV and
TLE-ICID modules only.)
Impairments
Echo
Echo is a reflection of the signal from a connected device back to that equipment. The
Echo Delay can be set from 0 to 100 mS in 125 µS (default is 0). The Attenuation,
relative to the strength of the original signal, can be set from 4 dB to 60 dB (default is 60
dB). Level accuracy will be maintained within ± 1 dB of setting.
White Noise
The White Noise operation provides a uniformly distributed noise source which is band
limited, starting at approximately 3.4 kHz. White Noise can be enabled for each line.
Default is disabled. If enabled, the White Noise volume can be set from 20 dBrn to 85
dBrn (default is 20 dBrn).
Noise source is broadbanded over 300 to 3400 Hz range (no C message weight). Level
accuracy is ± 2 dB for values from 20 to 85 dBrn.
