ITU-T G.751 applications) or BIP-8 Errors (for E3/

ITU-T G.832 applications) that have been detected by

the Receive DS3/E3 Framer, since the last read of

these registers. This register contains the MSB (or

Upper-Byte) value of this 16 bit expression.

2.3.8.6

PMON Parity Error Count Register -

LSB

This Reset-upon-Read register, along with the PMON

Parity Error Count Register - MSB (Address = 0x54)

contains a 16-bit representation of the number of P-

bit Errors (for DS3 applications), BIP-4 Errors (for E3/

ITU-T G.751 applications) or BIP-8 Errors (for E3/

ITU-T G.832 applications) that have been detected by

the Receive DS3/E3 Framer, since the last read of

these registers. This register contains the LSB (or

Lower-Byte) value of this 16 bit expression.

2.3.8.7

PMON FEBE Event Count Register -

MSB

This Reset-upon-Read register, along with the PMON

FEBE Event Count Register - LSB (Address = 0x57)

contains a 16-bit representation of the number of

FEBE Events that have been detected by the Receive

DS3/E3 Framer, since the last read of these registers.

This register contains the MSB (or Upper-Byte) value

of this 16 bit expression.

2.3.8.8

PMON FEBE Event Count Register -

LSB

This Reset-upon-Read register, along with the PMON

FEBE Event Count Register - MSB (Address = 0x56)

contains a 16-bit representation of the number of

FEBE Events that have been detected by the Receive

DS3/E3 Framer, since the last read of these registers.

This register contains the LSB (or Lower-Byte) value

of this 16 bit expression.
