General Information
Product Selection
TFF–3 is a WLL–terminal for the NMT450 network. New features include:
CLI (calling line indicator), scrambling (voice coding), immobilizer and metering pulse generator. The operating voltage for logic chips is 2.8V and
because of ROMless CPU, external program memory (flash) is used.

Land–line connector
The land–line connector is used to connect SLIC circuitry to land–line
phone.
The landline telephone is one of main user interfaces of the WLL terminal.
A standard landline telephone can be used. Both pulse dialling and
DTMF are supported in System Solution and Non–Transparent Access
Solution modes.
However. only DTMF dialling is supported in Transparent Acces Solution
mode.
Main parameters :
– nominal impedance is 600 ohm
– feeding Voltage –52 V +/– 3 V
– ringing Voltage –68 Vrms +/–3V
– max. 2–wire lenght is 100 m (with one connected telephone)
– 3 telephones parallel
