and counts REI indications. The TUPP+622 also allows insertion of tributary path
AIS as a consequence of any of the above alarm conditions. In addition, the
TUPP+622 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+622 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+622 operates from
either a single 19.44 MHz or a single 77.76 MHz line rate clock. The TUPP+622
is configured, controlled and monitored via a generic 8-bit microprocessor bus
interface.
The TUPP+622 is implemented in low power, +2.5 Volt Core and +3.3 Volt I/O,
CMOS technology. It has TTL compatible inputs and outputs and is packaged in a
304 pin SBGA package.
