PRBS Pattern Type
This bit selects the type of PRBS pattern that the T1 Transmit/
Receive framer will generate or detect. PRBS 15 (X15 + X14 +1)
Polynomial or QRTS (Quasi-Random Test Signal) Pattern can be
generated by the transmit or receive framer depending on whether
PRBS switch function is enabled or not (bit 3 in register 0x0121).
If the PRBS Switch function is disabled, T1 transmit framer will gen-
erate either PRBS 15 or QRTS pattern and output to the line inter-
face. PRBS 15 or QRTS pattern depends on the setting of this bit.
If the PRBS Switch function is enabled, T1 receive framer will gener-
ate either PRBS 15 or QRTS pattern and output to the receive back
plane interface. PRBS 15 or QRTS pattern depends on the setting
of this bit.
0 = Enables the PRBS 15 (X15 + X14 +1) Polynomial generation.
1 = Enables the QRTS (Quasi-Random Test Signal) pattern genera-
tion.

ERRORIns

0
Error Insertion
This bit is used to insert a single BERT error to the transmit or
receive output depending on whether BERT switch function is
enabled or not. (bit 3 in register 0x0121).
If the BERT Switch function is disabled, T1 transmit framer will insert
a single BERT error and output to the line interface if this bit is
enabled.
If the BERT Switch function is enabled, T1 receive framer will insert
a single BERT error and output to the receive back plane interface if
this bit is enabled.
A ‘0’ to ‘1’ transition will cause one output bit inverted in the BERT
stream.
NOTE: This bit only works if BERT generation is enabled.

DATAInv
R/W
0
BERT Data Invert:
This bit inverts the Transmit BERT output data and the Receive
BERT input data. 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
transmit framer will invert the BERT data before it outputs to the line
interface, and the T1 receive framer will invert the incoming BERT
data before it receives it.
If the BERT Switch function and this bit are both enabled, T1 receive
framer will invert the BERT data before it outputs to the line inter-
face, and the T1 transmit framer will invert the incoming BERT data
before it receives it.
0 - Transmit and Receive Framer will NOT invert the Transmit and
Receive BERT data.
1 - Transmit and Receive Framer will invert the Transmit and
Receive BERT data.
