GENERAL DESCRIPTION
ATM direct mapping and cell delineation are supported, so are packets (PPP) over SONET for POS mapping and frame processing.APPLICATIONS
● Edge and WAN ATM Switches● IP Routers, Packet Switches and Hubs
● Multi-protocol Switches
FEATURES
● A single chip solution for ATM UNI and packet over SONET● Provides the highest level of protection switching flexibility for up to 1:14 protected OC-3/STM-1 ports.
● Provides quad serial OC-3/STM-1 interfaces with integrated CDR, compatible with industry standard optical modules.
● Provides serial OC-12/STM-4 interfaces with integrated CDR, compatible with industry standard optical modules.
● Supports the mappings for any standard combination of STS-12c/AU-4c or STS-3c/AU4.
● Provides four 8-bit busses on the line side running at 19.44 MHz to connect OC-12 framers through a parallel interface or aggregate four low speed OC-3 devices into an OC-12 line.
● Supports both SONET and SDH on all interfaces. SONET/SDH is programmable per interface.
