Remote LOS and AIS Response

Figure 24

 shows the different 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 

Table 5 on page 19

 and 

Table 6 on 

page 20

The OCT 55 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.
