DS3/E3 Framer Functionality:
Performance Monitor:
Alarm and Error Insertion:
DS3/E3 frame format support
Supports the following out-of-frame criteria.
Alarm Detection
Performance Monitor Counter Functionality
AIS signal insertion toward the line side
IDLE signal insertion to the line side in the DS3 frame format
Supports automatic (in the receiver frame and CP-parity error condition) FEBE
insertion in the DS3 C-parity frame format
Supports manual RAI insertion in both DS3 and E3 G.751 frame format. The auto
RAI insertion is also supported in the E3 G.751 frame format during the receiver
OOF or LOS condition
Supports single error insertion for LCV (including BPV and illegal substitution),
frame, parity, C-Path Parity bit and RAI/RDI, parity-disagreement, X-bit
disagreement, FEBE event
Under software control, supports auto unchannelized all-1s insertion toward the
system side during receiver OOF, LOS, AIS, or DS3 IDLE condition
All counters operate in Real-Time Updating mode and 1-Second Latched mode
DS3—M13, M23, and C-parity
DS3 mode—3 or more frame bit errors in 16 consecutive F-bits, or at least 1
M-bit error in 2 out of 4 consecutive frames
E3 G.751 mode—At least 1 frame word error in 4 consecutive frames.
Loss Of Signal (LOS) detection in the dual-rail interface mode
IDLE signal detection in the DS3 mode
AIS detection
RAI/Remote Defect Indication (RDI) detection
Out-Of-Frame (OOF) detection
Severely Errored Frame (SEF) detection in the DS3 mode
All alarms, except the start of an SEF interrupt event, provide separate
maskable interrupt status for alarm state transition in- and out-state.
LCV counter
Excess 0 counts in the dual-rail interface mode
Frame error counts
Parity error counts in the DS3 frame format
Parity bit disagreement counts in the DS3 frame format
Path parity error counts in the DS3 C-Parity frame format
FEBE error counts in DS3 C-Parity frame format
X-bit disagreement counts in DS3 M13, C-Parity frame format
All counters except the LCV counter are 16-bits long and are able to hold 1-
second counts in the presence of a 10
LCV counter is 24-bits long and is able to hold every LCV in a 1-second period
without an overflow
All counters provide counter overflow status with maskable interrupt capability
