The ingress path also extracts the tributary path overhead bytes and alarm information into
serial streams.
The egress path of TUPP 2488 provides optional SDH payload conversions as follows:
•
•
The TUPP 2488 terminates the path overhead of any legal mix of STS-1/3c/12c/48c (VC-3/4/4-
4c/4-16c) payloads in a SONET/SDH STS-48/STM-16 stream. In the receive direction, the
TUPP 2488 detects path alarm conditions, detects and accumulates path BIPs (B3). It extracts
Remote Error Indications (REIs) from path status (G1), and monitors and accumulates path
Remote Error Indications (REIs) for performance monitoring. It accumulates and compares the
16 or 64 byte path trace (J1) message against an expected result. It extracts the received path
payload label (C2). All path overhead bytes are extracted and serialized on lower rate interfaces,
allowing additional external processing of overhead along with alarm information, if desired. In
the transmit direction, the TUPP 2488 creates and inserts the path BIPs (B3), optionally inserts a
16 or 64 byte path trace (J1) message, optionally inserts the path status byte (G1) and the path
payload label (C2) byte into the transmit stream. In addition to its basic processing of the
transmit SONET/SDH path overhead, the TUPP 2488 provides convenient access to all path
overhead bytes, which are inserted serially on lower rate interfaces, allowing additional external
sourcing of path overhead if desired. The TUPP 2488 also supports the insertion of a large
variety of errors into the transmit stream, such as framing pattern errors, pointer errors and BIP
errors, which are useful for system diagnostics and tester applications.
The TUPP 2488 does not support STS-1 (VC3/VC4) path overhead transparency.
