PRBS Pattern Type
This bit selects the type of PRBS pattern that the T1 Transmit/
Receive framer will generate or detect. PRBS 15 (X
15
+ X
14
+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 0xn121).
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 (X
15
+ X
14
+1) Polynomial generation.
1 = Enables the QRTS (Quasi-Random Test Signal) pattern genera-
tion.

Error Insertion
This bit is used to insert a single PRBS/QRTS error to the transmit
or receive output depending on whether PRBS switch function is
enabled or not. (bit 3 in register 0xn121).
If the PRBS Switch function is disabled, T1 transmit framer will
insert a single PRBS/QRTS error and output to the line interface if
this bit is enabled.
If the PRBS Switch function is enabled, T1 receive framer will insert
a single PRBS/QRTS 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 PRBS/
QRTS stream.

This bit only works if PRBS/QRTS generation is enabled.

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