GENERAL DESCRIPTION
The DS32506 (6 port), DS32508 (8 port), and
DS32512 (12 port) line interface units (LIUs) are
highly integrated, low-power, feature-rich LIUs for
DS3, E3, and STS-1 applications. Each LIU port in
these devices has independent receive and transmit
paths, a jitter attenuator, full-featured pattern
generator and detector, performance-monitoring
counters, and a complete set of loopbacks. An on-
chip clock adapter generates all line-rate clocks from
a single input clock. Ports are independently software
configurable for DS3, E3, and STS-1 and can be
individually powered down. Control interface options
include 8-bit parallel, SPI, and hardware mode.
