FCC Registered Phone Line Interface with Tone Transmitter/Decoder

Description

Features

The XE0068DT is an FCC registered

telephone line interface which includes a

DTMF transmitter, decoder and call progress

monitor. FCC rules limit transmit level and

require a 2-second billing delay at the start

of each call. The XE0068DT does not

merely clamp the incoming signal which

could cause signal distortion; but, uses an

Automatic Gain Control circuit to optimize

the transmit level over a wide range of input

signal levels. The integral DTMF transmitter,

decoder, and call progress monitor makes

the XE0068DT ideal for network signalling

applications.

* Small Size - 2.28" x 1.08" x 0.42"

* FCC Part 68 Registered

* Ring Detection and Hookswitch Control

* 1500 Volt Isolation;

* 800 Volt Surge Protection;

* An Integral 2-Second Billing Delay

* Auotomatic Gain Control optimizes

transmit level for any input level.

* Integral DTMF transmitter and decoder

* Call progress Monitor
