Inject Line Code Violation—Injects a single LCV error, depending on line mode and ZCS
selected. In T1 mode, the LCV injector waits for transmission of two consecutive pulses on the
data output before performing BPV error insertion and clearing the TVERR bit. Therefore, a
BPV error cannot be injected into a transmit data stream that does not contain two consecutive
ones. TVERR is latched until an opportunity to inject a BPV error is presented. This prevents
the receiving end from detecting: frame or multiframe bit errors, CRC errors, multiple BPV
errors (due to ZCS pattern corruption), or PRBS test pattern bit errors as a consequence of
error insertion. In E1 mode with HDB3 selected, the LCV injector sends two consecutive
BPVs of the same polarity, which causes the receiving end to detect a single LCV error.

Transmit FEBE Frame 15.
Transmit FEBE Frame 13.
Manual Transmit FEBE (Overrides INS_FE; addr 072)—Provides a manual override for
FEBE bits that are normally sent by the alarm formatter [INS_FE; addr 072]. When active,
FEBE_I controls the data output in TS0 bit 1 of frame 13 (FEBE13) and, FEBE_II controls the
data output in TS0 bit 1 of frame 15 (FEBE15).
0 = no effect
1 = inject line code violation

NOTE(S):
indicate SMF I and SMF II errors. Each error signal is latched and held for one full multiframe to
compensate for phase differences between receive and transmit multiframe timing.
