requesting version information from the TLE. After all valid and proper entries, a three
beep sequence is issued. After an invalid entry, a longer single tone is issued.
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 for access to programming mode. (Only available with TLE-ADV
and TLE-TEST modules.)
Conference Type
Conference Type allows for two different operations when a Conference Call is
attempted. The differences in operation are detailed below (C.O. Conference is based
upon Three Way Calling):
A typical Conference Call is initiated by generating a FLASH, Recall Dial Tone is heard,
then a phone number is dialed to access the third (or fourth) party. If PBX Conference is
selected, the originator of the conference must wait until the party answers before
generating another Flash to bring all parties together.
• PBX Conference
Up to 4 lines may be connected in conference. The Called Party must answer
before the second Flash to connect parties. Any party may hang up and all
the others in the conference will remain connected
• Central Office Conference
Only three lines may be connected in a conference if a FLASH is generated before the
Called Party answers, the remaining parties will hear ringing. If the Originating Party
hangs up, all connections will be terminated
Test Tones
Test Tones is a user programmable single or dual tone that is accessed by dialing the
Special Test Tone Phone Number. This phone number is set on the Phone Number
screen. Default is 83785. With a selection of Single Tone the system will only generate
the first tone. With a selection of Tone 1 + Tone 2 the system will generate both tones
with the specified frequencies and amplitudes. Purchase of the International Module adds
the selection of Tone 1 x Tone 2. The system will generate Tone 1 modulation by Tone 2.
In this implementation only the fundamental and upper side tone are generated, both at
the amplitude programmed for Tone 1.
Frequency range is 10 to 3000 Hz and output level is -0 dBm to -60 dBm.
If the Test Tone is set for dual tone output, the maximum level should be limited to -6
dBm per tone.
Off-hook Mode
Off-hook Mode is how the TLE handles a call when a device connected to the line meets
the minimum Off-hook time. The options include: Normal (issues dial tone and waits for
dialing), Hotline (will automatically ring the number programmed into the Revert to Dial
Tone location), and Silent (will connect a device to a quiet Battery). Each line may be
programmed individually.
