RxPRBSLock
RO
0
Lock Status
This bit indicates whether or not the Receive or Transmit PRBS lock
has obtained. The exact function of this bit depends on whether
PRBS switch function is enabled or not. (bit 3 in register 0xn121).
If the PRBS Switch function is disabled, T1 receive framer will
declare LOCK if PRBS/QRTS has locked onto the input pattern.
If the PRBS Switch function is disabled, T1 transmit framer will
declare LOCK if PRBS/QRTS has locked onto the input pattern.
0 = Indicates the Receive PRBS/QRTS has not Locked onto the
input patterns.
1 = Indicates the Receive PRBS/QRTS has locked onto the input
patterns.

Receive PRBS Detection/Generation Enable
This bit enables or disables the receive PRBS/QRTS pattern detec-
tion or generation. The exact function of this bit depends on whether
PRBS switch function is enabled or not. (bit 3 in register 0xn121).
If the PRBS switch function is disabled and if this bit is enabled, T1
Receive Framer will detect the incoming PRBS/QRTS pattern from
the line side and declare PRBS/QRTS lock if incoming data locks
onto the PRBS/QRTS pattern.
If the PRBS switch function and this bit are both enabled, T1 Trans-
mit Framer will detect the incoming PRBS/QRTS pattern from the
transmit backplane interface and declare PRBS/QRTS lock if incom-
ing data locks onto the PRBS/QRTS pattern.
0 = Disables the Receive PRBS/QRTS pattern detection.
1 = Enables the Receive PRBS/QRTS pattern detection.

0
Transmit PRBS Generation Enable
This bit enables or disables the Transmit PRBS pattern generator.
The exact function of this bit depends on whether PRBS switch
function is enabled or not. (bit 3 in register 0xn121).
If PRBS switch function is disabled, T1 Transmit Framer will gener-
ate the PRBS 15 or QRTS pattern to the line side if this bit is
enabled.
If PRBS switch function is enabled, T1 Receive Framer will generate
the PRBS 15 or QRTS pattern to the receive backplane interface if
this bit is enabled.
0 = Disables the Transmit PRBS/QRTS pattern generator.
1 = Enables the Transmit PRBS/QRTS pattern generator.

Receive Framer Bypass
This bit enables or disables the Receive T1 Framer bypass.
0 = Disables the Receive T1 framer Bypass.
1 = Enables the Receive T1 Framer Bypass.

0
Transmit Framer Bypass
This bit enables or disables the Transmit T1 Framer bypass.
0 = Disables the Transmit T1 framer Bypass.
1 = Enables the Transmit T1 Framer Bypass.
