0
Lock Status
This bit indicates whether or not the Receive or Transmit BERT lock
has obtained. The exact function of this bit depends on whether
BERT switch function is enabled or not. (bit 3 in register 0x0121).
If the BERT Switch function is disabled, T1 receive framer will
declare LOCK if BERT has locked onto the input pattern.
If the BERT Switch function is disabled, T1 transmit framer will
declare LOCK if BERT has locked onto the input pattern.
0 = Indicates the Receive BERT has not Locked onto the input pat-
terns.
1 = Indicates the Receive BERT has locked onto the input patterns.

Receive BERT Detection/Generation Enable
This bit enables or disables the receive BERT pattern detection or
generation. The exact function of this bit depends on whether BERT
switch function is enabled or not. (bit 3 in register 0x0121).
If the BERT switch function is disabled and if this bit is enabled, T1
Receive Framer will detect the incoming BERT pattern from the line
side and declare BERT lock if incoming data locks onto the BERT
pattern.
If the BERT switch function and this bit are both enabled, T1 Trans-
mit Framer will detect the incoming BERT pattern from the transmit
backplane interface and declare BERT lock if incoming data locks
onto the BERT pattern.
0 = Disables the Receive BERT pattern detection.
1 = Enables the Receive BERT 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 0x0121).
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.
