PM5371 TUDX
Permits switching of any combination of SONET VT1.5, VT2, VT3, VT6, or STS-1 channels. Permits switching of any combination of SDH TU11, TU12, TU2, or TU3 channels. Operates in conjunction with the PM5362 TUPP-PLUS VT/TU Payload Processor/Performance Monitor, which aligns SONET VTs or SDH TUs so they can be switched by the TUDX. Cascadable in a systolic or bussed manner to allow larger switching arrays to be implemented. Provides control outputs that are programmable on a per-timeslot basis to facilitate construction of larger switching arrays. Provides a generic 8-bit microprocessor bus interface for configuration, control, and status monitoring. Low power, +5 V, CMOS technology. Device has TTL-compatible inputs and outputs. Available in a 160-pin Plastic Quad Flat Pack (PQFP) (28 by 28 mm) package.
VT/TU Cross-Connect Switch
FEATURES
Monolithic, SONET/SDH, single-stage, non-blocking array of time switches for cross-connecting SONET Virtual Tributaries (VTs) or SDH Tributary UNITs (TUs). Provides non-blocking switching between two STS-3 (STM-1) byteserial input streams and two STS-3 (STM-1) byte-serial output streams. Operates from a single 19.44 MHz clock. Provides parity checking on input data busses and parity generation on output data busses. Allows programmable idle code insertion on a per-VT or per-TU basis.
