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 Automatic Gain Control circuit optimizes a wide range of input signal levels for placement on the telephone line. The XE0068 can support data, fax, voice, and DTMF signalling applications.

PIN DESCRIPTIONS
PIN 1 13 NAME VCC D/V I/O --I DESCRIPTION +5 Volt power; A TTL Low on Data/Voice selects a transmit level output of 0 dBm for voice or DTMF signaling applications. A High on Data/Voice sets a maximum -9 dBm transmit level for data transfer. Ground reference for the XE0068; XMIT is the Analog input signal to the XE0068. The input impedance on XMIT is typically 10 Kohms at 1800 Hz. Signals placed on XMIT less than 0 dBm will be placed on the telephone line at a maximum of -9 dBm when the Data/Voice signal is driven high and a maximum of 0 dBm when Data/Voice is driven low. RCVR is the Analog output signal from the 2-4 wire converter. The output impedance of RCVR is typically 10 ohms at 1800 hz. The signal level on RCVR will be within 1 dBm of the received signal level present on the telephone line. Hookswitch control. A High on OH closes the internal relay to connect the equipment to the phone line. Ring Indicate, output, active low, TTL, indicates the modem is receiving a ring signal. Ring connection to the phone line (RJ11 Pin 4).
