VT/TU Cross-Connect Switch
TUDX
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) byte-
serial 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.
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.
