00 - Transmission of Yellow Alarm is disabled.
01 - The framer transmits Yellow Alarm by converting the second MSB of
all outgoing twenty-four DS0 channel into zero.
10 - The framer transmits Yellow Alarm by sending the Super-frame Align-
ment Bit (Fs) of Frame 12 as one.
11 - The framer transmits Yellow Alarm by converting the second MSB of
all outgoing twenty-four DS0 channel into zero.
N Mode:
00 - Transmission of Yellow Alarm is disabled.
01, 10 or 11 - The framer transmits Yellow Alarm by converting the second
MSB of all outgoing twenty-four DS0 channel into zero.
ESF Mode:
When the framer is in ESF mode, it transmits Yellow Alarm pattern of eight
ones followed by eight zeros (1111_1111_0000_0000) through the 4Kbit/s
data link bits.
00 - Transmission of Yellow Alarm is disabled.
01 - The following scenario will happen:
1.
If Bit 0 of Yellow Alarm Generation Select forms a pulse width
shorter or equal to the time required to transmit 255 patterns on the
4Kbit/s data link, the alarm is transmitted for 255 patterns.
2.
If Bit 0 of Yellow Alarm Generation Select forms a pulse width
longer than the time required to transmit 255 patterns on the 4Kbit/s
data link, the alarm continues until Bit 0 goes LOW.
3.
A second pulse on Bit 0 of Yellow Alarm Generation Select during
an alarm transmission resets the pattern counter. The framer will
send another 255 patterns of the Yellow Alarm.
10 - Bit 1 of the Yellow Alarm Generation Select forms a pulse that controls
the duration of Yellow Alarm transmission. The alarm continues until Bit 1
goes LOW.
11 - The following scenario will happen:
1.
If Bit 0 of Yellow Alarm Generation Select forms a pulse width
shorter or equal to the time required to transmit 255 patterns on the
4Kbit/s data link, the alarm is transmitted for 255 patterns.
2.
If Bit 0 of Yellow Alarm Generation Select forms a pulse width
longer than the time required to transmit 255 patterns on the 4Kbit/s
data link, the alarm continues until Bit 0 goes LOW.
3.
A second pulse on Bit 0 of Yellow Alarm Generation Select during
an alarm transmission resets the pattern counter. The framer will
send another 255 patterns of the Yellow Alarm.
T1DM Mode:
00 - Transmission of Yellow Alarm is disabled.
01, 10 or 11 - The framer transmits Yellow Alarm by setting the Yellow
Alarm bit (Y-bit) to zero.
