RLIU Alarms

RLIU Bipolar Violation (BPV) Alarm.
The bipolar violation (BPV) alarm is used only in the single-rail mode of
operation. When B8ZS(DS1)/HDB3(CEPT) coding is not used (i.e., CODE = 0), any violations in the receive data
(such as two or more consecutive ones on a rail) are indicated on the RND/BPV outputs. When B8ZS(DS1)/
HDB3(CEPT) coding is used (i.e., CODE = 1), the HDB3/B8ZS code violations are reflected on the RND/BPV out-
puts.
DS1 Receiver Specifications
During DS1/T1 operation, the RLIU will perform as specified in Table 10.
