Bit #

Default
Bit 7: BERT Real-Time Synchronization Status (BSYNC). Real-time status of the synchronizer (this bit is not
latched). This bit is set when the incoming pattern matches for 32 consecutive bit positions. It is cleared when six
or more bits out of 64 are received in error. Refer to BSYNC in the BERT status register, TR.SR9, for an interrupt-
generating version of this signal.
Bit 6: BOC Detected (BD). A real-time bit that is set high when the BOC detector is presently seeing a valid
sequence and set low when no BOC is currently being detected.
Bit 5: Transmit Current-Limit Exceeded (TCLE). A real-time bit that is set when the 50mA (RMS) current limiter
is activated, whether the current limiter is enabled or not.
Bit 4: Transmit Open-Circuit Detect (TOCD). A real-time bit that is set when the device detects that the TTIP and
TRING outputs are open-circuited.
Bits 0 – 3: Receive Level Bits (RL0 to RL3). Real-time bits
NOTE: RL0 through RL3 only indicate the signal range as specified by the EGL bit in TR.LIC1. Example; if EGL =
1 and in T1 mode, RL0 through RL3 will only indicate a signal range of >-2.5dB to –15dB even if the signal is < -
15dB.
