FRM_RAI
Remote Alarm Indication.
A 1 indicates the receive framer
detected a remote (yellow) alarm or detected an RAI indication
on the TDM bus from the mapper.
D4: Bit 2 of all time slots is a 0 for one frame. (ANSIT1.403 sec-
tion 9.1.)
DDS: Bit 6 of time slot 24 is a 0 for 12 frames.
ESF: Option 0: An alternating pattern of eight ones followed by
eight zeros in the ESF data link for 10 consecutive times. (ANSI
T1.403 section 9.1.)
Option 1: A pattern of all ones in the ESF data link for 10 con-
secutive times.
CEPT Basic Frame: RAI is activated when bit 3 of the NOTFAS
frame is 1 RAC consecutive times. RAI is deactivated when bit 3
of the NOTFAS frame is a 0 RDC consecutive times. RAI activa-
tion count (RAC) and RAI deactivation count (RDC) are provi-
sionable in
Section Table 313. FRM_PMGR3, Performance
Monitor Global Register 3 (R/W) on page 248
.
Option 0: Bit 3 of the NOTFAS frame is a 1 one consecutive
time. RAI is inactive when bit 3 is set to a 0.
Option 1: RAI is set on three consecutive ones and deactivated
on three consecutive zeros.
Option 2: Bit 3 of the NOTFAS frame is a 1 four consecutive
times. RAI is inactive when bit 3 is set to a 1 in less than two
consecutive occasions. (O.162 section 2.1.4.)
Option 3: RAI is set on five consecutive ones and deactivated
on five consecutive zeros. (ETS 300.417-1-1.)
CEPT CRC-4 Multiframe: Reception of 1 bit A with a content of
1. (G.965 section 16.1.2)
Sa6 = 00x1 Event.
This bit indicates detection of an Sa6 = 00x1
event. The Sa6 code is detected synchronously to the CRC-4
multiframe and is not counted during loss of CRC-4 multiframe
alignment. This detection is not qualified by Sa5 = 1, unlike bits
6 and 8 of
Section Table 394. FRM_PMLR13, Performance
Monitor Link Register 13 (COR) on page 286
.
Sa6 = 001x Event.
This bit indicates detection of an Sa6 = 001x
event. The Sa6 code is detected synchronously to the CRC-4
multiframe and is not counted during loss of CRC-4 multiframe
alignment. This detection is not qualified by Sa5 = 1, unlike bits
7 and 8 of
Table 394
