H2TU-C-319 List 4E
Remote LOS and AIS Response
shows the differing ways the H2TU-R can respond to the network, depending on the configuration of
the TLOS, NLBP, FT1, ALMP, and NAIS configuration options described in
and
Figure 30.

The OCT55 test pattern can be used in unframed mode to stress the system and verify data integrity. In an SF or
ESF framing mode, excessive zero anomalies may occur, which causes the H2TU-C to report ES, SES, and UAS
errors according to ANSI T1.231-1997.
