Chapter 1. Introduction2 0 TSU 600 User Manual 61200.076L2-1Pattern GenerationThe TSU 600 offers two available test patterns: QRSSand 511.QRSS PatternThe QRSS pattern is commonly used to simulate realdata in T1 interfaces. This pattern can be assigned toappear in all DS0s or only in TST DS0s. When QRSS isset in all DS0s and one of the network loopbackspreviously described is activated at the far end, a totalend-to-end integrity check can be run without theneed for any external test equipment. When QRSS isassigned to TST DS0s, an integrity check of the linkcan be run along with normal data flow. The TSTDS0s are user assigned as part of the DS0 Map.511 PatternThe 511 pattern is generated and checked by anNx56/64 serial interface option card. It only appearsin the DS0s assigned to the Nx56/64 port which isgenerating the pattern. When used in conjunctionwith the port loopback at the far end as previouslydescribed, an end-to-end integrity check can be madeon the DTE ports.
