SONET/SDH TRIBUTARY UNIT CROSS CONNECT
1
FEATURES
• A 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 buses and parity generation on output
data buses.
• 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 PM5361 TUDX SONET/SDH Tributary Unit
Payload Processor which aligns SONET VTs or SDH TUs such that they can
be switched by the TUDX.
• Cascadable in a systolic or bused 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 programmable delay to match data skew in the systolic array
application.
• Provides a generic 8-bit microprocessor bus interface for configuration,
control, and status monitoring.
• Low power, +5 Volt, CMOS technology. Device has TTL compatible inputs
and outputs.
• 160 pin metric quad flat pack (MQFP) package.
