Remote LOS and AIS Response

Figure 26 shows the different ways the H2TU-R can respond to the network, depending on the configuration of
the TLOS, NLBP, FT1, AMLP, and NAIS configuration options described in
page 18. See Table 13 on page 25

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 cause the H2TU-C to report ES, SES, and UAS
errors according to ANSI T1.231-1997.
