51/155/622/2488 Mbit/s SONET/SDH Cell/Packet Interface — Intel IXF6048
406/7 specification says to ignore mismatch and unstable alarms when there are phase changes in
the incoming signal.
The Trace Identifier Mismatch is also provided at the RPAL serial alarm bus output and the J1
received byte is serially accessible at RPOH bus output pin.
4.4.1.6.2 B3 Byte
This byte is used for Higher Order Path error monitoring. The error events are counted in a 16-bit
counter accessible via registers B3_ECNT.
The B3 counter can be used either as a bit or a block counter configurable via register R_HPT_C1.
Based on the number of the B3 detected errors per frame, an HP-REI value is encoded. This value
is internally looped to the transmitter and provided serially at the Receive Path Alarm bus output,
RPAL.
4.4.1.6.3 C2 Byte Signal Label
This byte indicates the composition of the payload (value 13H for ATM mapping). A change in the
C2 byte for three or five (configurable via register R_HPT_C1) consecutive frames is indicated in
register IS_HPT and allows the updating of register R_C2 providing the value of the receive
accepted C2 Signal Label (filtered value). This value is also provided at RSAL serial alarm bus
output.
An unstable receive signal label is declared when the receive C2 byte has been detected different
from the C2 of the previous frame for 3 or 5 times (configurable via register R_HPT_C2), and
during this integration period, the value of C2 has not been stable for 3 (or 5) consecutive received
frames. C2Unstable alarm is indicated in register IS_HPT. If 3 (or 5) consecutive received C2
values are detected as identical, the C2Unstable alarm is cleared.
An expected value of C2 can be programmed in register EXP_C2. If the received filtered C2 value
(accepted signal label) is not equal to the expected value and is not 00H (Unequipped Indication) or
01H (equipped-non specific), this is indicated in register IS_HPT via the HptSlm (HPT Signal
Label Mismatch). The HptSlm alarm is also provided at the RPAL serial alarm bus output.
Unstable and mismatch detection are two independent processes, but it is possible via
configuration register R_HPT_C1 to force the HptSlm (C2 Signal Label Mismatch Alarm) when
received C2 is unstable.
VC-AIS is defined as all '1's. in C2 (new G.783 specifications). Five consecutive frames are
required for the VC-AIS detection which is indicated in register IS_HPT.
The C2 received byte is also serially accessible at RPOH bus output pin.
4.4.1.6.4 Unequipped Detection
The unequipped detector (C2 = all '0's) requires 5 frames before it is indicated in register IS_HPT.
The unequipped alarm is also provided at the RPAL_i (i = 0, 1, 2, 3) serial alarm bus output.
All the necessary information is provided to and from the monitoring function to support either
“supervisory unequipped” or “non supervisory unequipped” in the case of a network not
supporting the Tandem Connection. The following alarms and indication are accessible in registers
IS_HPT, and B3_ECNT:
