DS3161/DS3162/DS3163/DS3164
integration counter declares an AIS condition when it has been active for a total of 10 to 17 DS3 frames. The AIS
integration counter is active (increments count) when an AIS signal is present, it is inactive (holds count) when an
AIS signal is absent, and it is reset when an AIS signal is absent for 10 to 17 consecutive DS3 frames. An AIS
condition is terminated when an AIS signal is absent for 10 to 17 consecutive DS3 frames.
A Receive Unframed All 1’s (RUA1) condition is declared if in each of 4 consecutive 2047 bit windows, five or less
zeros are detected and an OOF condition is continuously present. A RUA1 condition is terminated if in each of 4
consecutive 2047 bit windows, six or more zeros are detected or an OOF condition is continuously absent.
An Idle Signal (Idle) is a DS3 signal with valid F-bits, M-bits, and P-bits (P1 and P2). The X-bits (X1 and X2) are set
to one, C31, C32, and C33 are set to zero, and the payload bits are set to a 1100 pattern starting with 11 immediately
after each overhead bit. In C-bit mode, an Idle Signal is present when a DS3 frame is received with valid F-bits, M-
bits, and P-bits, both X-bits set to one, C31, C32, and C33 set to zero, and all but seven or fewer payload data bits
matching the overhead aligned 1100 pattern. In M23 mode, an Idle signal is present when a DS3 frame is received
with valid F-bits, M-bits, and P-bits, both X-bits set to one, and all but seven or fewer payload data bits matching
the T3 overhead aligned 1100 pattern. An Idle signal is absent when a DS3 frame is received that does not meet
aforementioned criteria for an Idle signal being present. The Idle integration counter declares an Idle condition
when it has been active for a total of 10 to 17 DS3 frames. The Idle integration counter is active (increments count)
when an Idle signal is present, it is inactive (holds count) when an Idle signal is absent, and it is reset when an Idle
signal is absent for 10 to 17 consecutive DS3 frames. An Idle condition is terminated when an Idle signal is absent
for 10 to 17 consecutive DS3 frames.
A Remote Defect Indication (RDI) condition (also called a far-end SEF/AIS defect condition) is declared when four
consecutive DS3 frames are received with the X-bits (X1 and X2) set to zero. An RDI condition is terminated when
four consecutive DS3 frames are received with the X-bits set to one.
A DS3 Framing Format Mismatch (DS3FM) condition is declared when the DS3 format programmed (M23, C-bit)
does not match the incoming DS3 signal framing format. A DS3FM condition is terminated when the incoming DS3
signal framing format is the same format as programmed. Framing errors are determined by comparing F-bits and
M-bits to their expected values. The type of framing errors accumulated is programmable (OOFs, F & M, F, or M).
An OOF error increments the count whenever an OOF condition is first detected. An F & M error increments the
count once for each F-bit or M-bit that does not match its expected value (up to 31 per DS3 frame). An F error
increments the count once for each F-bit that does not match its expected value (up to 28 per DS3 frame). An M
error increments the count once for each M-bit that does not match its expected value (up to 3 per DS3 frame).
P-bit parity errors are determined by calculating the parity of the current DS3 frame (payload bits only), and
comparing the calculated parity to the P-bits (P1 and P2) in the next DS3 frame. If the calculated parity does not
match P1 or P2, a single P-bit parity error is declared.
C-bit parity errors (C-bit format only) are determined by calculating the parity of the current DS3 frame (payload bits
only), and comparing the calculated parity to the C-bits in subframe three (C31, C32, and C33) in the next DS3 frame.
If the calculated parity does not match C31, C32, or C33, a single C-bit parity error is declared.
FEBE errors (C-bit format only) are determined by the C-bits in subframe four (C41, C42, and C43). A value of 111
indicates no error and any other value indicates an error.
The receive alarm indication (RAI) bit will be set high in the transmitter when one or more of the indicated alarm
conditions is present, and low when all of the indicated alarm conditions are absent. Setting the receive alarm
indication on LOS, SEF, LOF, or AIS is individually programmable (on or off).
The Application Identification Channel (AIC) is stored in a register bit. It is determined from the C11 bit. The AIC is
set to one (C-bit format) if the C11 bit is set to one in thirty-one consecutive multiframes. The AIC is set to zero (M23
format) if the C11 bit is set to zero in four of the last thirty-one consecutive multiframes. Note: The stored AIC bit
must not change when an LOS, OOF, or AIS condition is present.
A FEBE is transmitted by default upon reception of a DS3 frame in which a C-bit parity error or a framing error is
detected and counted.
