1200bps Component Modem
Description
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.
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.
