The PMC 69 provides a four link Inverse Multiplexing for ATM (IMA) interface on a PMC module format. The PMC 69 allows four physically independent T1 E1 streams to be terminated and their data channels formed into a maximum of four logical IMA groups. An on-board ATM Segmentation and Reassembly Device (SAR) then performs ATM terminal functions supporting AAL 0, AAL 3/4 and AAL 5 operations.
The PMC 69 can be used on Cyclone's PCI and Compact PCI Intelligent I/O Controllers as a component of an Integrated Access Controller or Network Translation Subsystem. Diagnostic and Sample code is available for both the IMA and SAR functions.
