DESCRIPTION

The PM7341 S/UNI-IMA-84 is a monolithic integrated circuit that implements the Inverse Multiplexing for ATM (IMA 1.1) protocol with backward compatibility to IMA 1.0 and the Transmission Convergence (TC) layer function. The S/UNIIMA-84 has two line side interface modes that determine the total number of links supported: the Scalable Bandwidth Interconnect (SBI) bus interface mode and the Clock and Data interface mode. In SBI mode, the S/UNI-IMA-84 supports up to 84 T1, 63 E1 and 3 DS3 (TC only) links where each link is dynamically configurable to support either IMA 1.1, backward compatible IMA 1.0, ATM over T1/E1 and up to three ATM over DS3 streams (using HEC delineation).

APPLICATIONS

The S/UNI-IMA-84 is ideal for the following applications:

• ATM Multiservice Switches - IMA/UNI and Any Service Any Port linecards

• Wireless Base Station Controllers
