Abstract:

A system for cross conversion of plesiochronous digital hierarchy (PDH) and asynchronous transfer mode (ATM) data is disclosed. A PDH DS3 signal is received and demultiplexed into 28 DS1 data. ATM adaptation layer modules convert the 28 DS1 data to ATM cell streams. The ATM cell streams are multiplexed into a single ATM MUX cell stream and then multiplexed with another cell stream. A router receives the combined multiplexed cell stream, adds a header field, and outputs an ATM cell. The system functions to also convert the ATM cell data to DS3 PDH data using the same basic components.
