DESCRIPTION
The PM5362 TUPP-PLUS SONET/SDH Tributary Unit Payload Processor /
Performance Monitor is a monolithic integrated circuit that implements a
configurable, multi-channel, payload processor that aligns and monitors
performance of SONET virtual tributaries (VTs) or SDH tributary units (TUs.).
When configured for SONET compatible operation, the TUPP-PLUS transfers all
tributaries in the three STS-1 synchronous payload envelopes of an incoming
STS-3 byte serial stream to the three STS-1 synchronous payload envelopes of
an outgoing STS-3 byte serial stream. Similarly, when configured for SDH
compatible operation, the TUPP-PLUS transfers all tributaries in the single AU4
or three AU3 administrative units of an incoming STM-1 byte serial stream to a
single AU4 or three AU3 administrative units of an outgoing STM-1 byte serial
stream. The TUPP-PLUS compensates for pleisiochronous relationships
between incoming and outgoing higher level (STS-1, AU4, AU3) synchronous
payload envelope frame rates through processing of the lower level (VT6, VT3,
VT2, VT1.5, TU3, TU2, TU12, TU11) tributary pointers.
The TUPP-PLUS is configurable to process any legal mix of tributaries. Each VT
group can be configured to carry any one of the four tributary types (VT1.5, VT2,
VT3, or VT6) and each TUG2 can be configured to carry any one of three
tributary types (TU11, TU12, or TU2). TUG2s can be multiplexed into a VC3 or a
TUG3. Alternatively, each TUG3 can be configured to carr y a TU3.
The TUPP-PLUS operates in conjunction with the PM5344 SONET/SDH Path
Terminating Transceiver to align tributaries such that they can be switched by the
PM5371 TUDX SONET/SDH Tributary Unit Cross-Connect.
The TUPP-PLUS provides useful maintenance functions. They include, for each
tributary, detection of loss of pointer, detection of AIS alarm, detection of tributary
path signal label mismatch and unstable alarms, detection of tributary path trace
mismatch and unstable alarms. Optionally, interrupts can be generated due to
the assertion and removal of any of the above alarm conditions. The
TUPP-PLUS counts received tributary path BIP-2 (BIP-8 for TU3) errors on a
block or bit basis and counts FEBE indications. The TUPP-PLUS also allows
insertion of tributary path AIS as a consequence of any of the above alarm
conditions. In addition, the TUPP-PLUS may insert tributary idle (unequipped)
into any tributary. Incoming tributary path trace messages and path signal labels
are stored in a set of microprocessor accessible registers. The TUPP-PLUS can

also insert inverted new data flag fields that can be used to diagnose
downstream pointer processing elements.
No auxiliary high speed clocks are required as the TUPP-PLUS operates from
either a single 19.44 MHz or a single 38.88 MHz line rate clock. The
TUPP-PLUS is configured, controlled and monitored via a generic 8-bit
microprocessor bus interface.
The TUPP-PLUS is implemented in low power, +5 Volt, CMOS technology. It has
TTL compatible inputs and outputs and is packaged in a 160 pin HPPQFP
package.
