FCC Registered Phone Line Interface

Description

The XE0068 is a compact, FCC registered telephone

line interface. Designers can use the XE0068 in their

telecom designs without going through the time and

expense of FCC Part 68 Registration. This makes the

XE0068 perfect for low volume and prototype designs.

To attain FCC part 68 Registration on the XE0068,

Xecom was required to control the output level to the

telephone line and provide a 2-second billing delay.

Xecom designed an Automatic Gain Control circuit to

meet FCC rules limiting transmit level. Xecom's Auto-

matic Gain Control circuit optimizes a wide range of in-

put signal levels for placement on the telephone line.

The XE0068 can support data, fax, voice, and DTMF

signalling applications.
