1.6 Line Interface Applications
CN8223
ATM Transmitter/Receiver with UTOPIA Interface
1.6 Line Interface Applications
With minimal glue logic, the CN8223 provides interfaces to STS-3c, STM-1,
DS3, E3, TAXI, DS1, or E1 equipment. Multiple line rates can be supported with
a single design if the line interface is on a daughter card. Figure 1-5 illustrates the
configuration for several line interfaces.
