1200bps Component Modem

Description

Features

The XE1214B5 is a complete, self contained

1200/300 bps modem in small, component form. It

contains all circuitry necessary for a complete

modem, including an internal, FCC Registered,

Data Access Arrangement (DAA) for direct

connection to the telephone line, and a serial TTL

interface. With the addition of line driver and

receiver ICs (such as the MC1488 and MC1489),

this serial interface may be easily converted to a

full RS232C serial interface.

• Small Size -2.28" x 1.0" x 0.5"

• FCC Part 68 Registered

• Fully Bell 212A/103 and CCITT V.22/V.21

Compatible

• Complete Industry Standard "AT" Command

Set

• TTL Serial Interface

• Call Progress Monitoring

• DTMF and Pulse Dialing

• Software Controlled Audio Output

• UL Recognized Component

• CSA Recognized Component

• +5 Volt Power Only

The XE1214B5 uses the industry standard "AT"

commands. This allows the XE1214B5 to operate

with most communications software. It supports

full duplex, 1200/300 bps, data transfer with either

Bell 212A/103 or CCITT V.22/V.21 modulation.

The XE1214B5 includes the capability to monitor

call progressand generate DTMF and guard tones

required for CCITT V.22/V.21 communication. It

operates in the asynchronous mode and provides

analog loopback, digital loopback and remote

digital loopback functions for testing purposes.
