Introduction
OCM-22 is a low-cost modem solution for low-speed
embedded applications. OCM22 includes a simplified
AT command set and supports data rates from
300 bits/s (V.21) to 2400 bits/s (V.22bis) and only
requires a CSP1034 or CSP1035A to make a com-
plete modem.
OCM-22 provides a choice of two system interfaces,
a serial interface or an 8-bit parallel interface. The
serial interface can be used in systems that have an
available serial port. In other systems, the parallel
interface can be I/O or memory mapped onto typical
processor buses.
In typical applications, OCM-22 is paired with Agere's
CSP1035A silicon DAA to implement a low-cost
worldwide modem. OCM-22 can also be used with
Agere's CSP1034 line codec for traditional trans-
former-based DAA designs.
