6.1
In E1 mode, Remote Defect Indication (RDI) is implemented in compliance with ITU-T
G.775 (chapter 6):
Criteria for detection and clearance of a Remote Defect Indication (RDI) defect, chapter
6.1 and 6.2:
“A Remote Defect Indication (RDI) defect at 2048 kbit/s TS-16 path termination functions
is detected (status register bit FRS1.RDI) when the incoming signal has the "alarm
indication to the remote" bit set to binary ONE ("1") for z consecutive CAS multiframe
periods, where z = 1 ...5. z is not provisionable.
The RDI defect is cleared when the incoming signal has the "alarm indication to the
remote end" bit set to binary ZERO ("0") for z consecutive CAS multiframe periods.
Note: The alarm indication to the remote end bit is the "y bit" in TS-16´s frame 0 of the
CAS multiframe defined in 5.1.3.2.2/G.704.”
“A Remote Defect Indication (RDI) defect at 2048 kbit/s path termination functions is
detected when the incoming signal has the "Remote alarm indication" bit set to binary
ONE ("1") for z consecutive double frame periods, where z = 2,...5. z is not provisionable.
The RDI defect is cleared when the incoming signal has the "Remote alarm indication"
bit set to binary ZERO ("0") for z consecutive double frame periods.
Note: The Remote alarm indication bit is the "A bit" in the 2048 kbit/s frame defined in
Recommendation G.704.”
Implementation:
Controlling of the number (z) of multiframe periods or double frame periods is performed
by the register bits FMR4.RDIS(1:0) and FMR4.RDIC(1:0). The RDI bit FRS1.RDI is a
status bit, not an interrupt status bit.

Note: As in FALC56 V2
In T1/J1 mode, the Automatic Remote Alarm feature (AXRA) is now compliant with
ANSI T1.403-1999 (see
fulfilled.)
