DS3/E3 FRAMER IC

XRT7250

REV. 1.1.1

109

This Read-Only register, along with the Frame Parity

Errors - One-Second Accumulator Register - LSB

(Address = 0x71) contains a 16-bit representation of

the number of Frame Parity Errors that have been de-

tected by the Receive DS3/E3 Framer block, within

the last One-Second sampling period. This register

contains the MSB (or Upper-Byte) value of this 16 bit

expression.

2.3.8.16 One-Second Frame Parity Error Accu-

mulator Register - LSB

This Read-Only register, along with the Frame Parity

Errors - One-Second Accumulator Register - MSB

(Address = 0x70) contains a 16-bit representation of

the number of Frame Parity Errors that have been de-

tected by the Receive DS3/E3 Framer block, within

the last one-second sampling period. This register

contains the LSB (or Lower-Byte) value of this 16 bit

expression.

2.3.8.17 One-Second Frame CP-Bit Error Accu-

mulator Register - MSB

This Read-Only register, along with the Frame CP-Bit

Error - One-Second Accumulator Register - LSB (Ad-

dress = 0x73) contains a 16-bit representation of the

number of CP Bit Errors tjhat have been detected by

the Receive DS3/E3 Framer block, within the last

one-second sampling period. This register contains

the MSB (or Upper Byte) value of this 16-bit expres-

sion.
