5.5.6.1
ANSI T1.231 for T1 and J1 Modes
For short-haul mode, loss is detected if the received signal level is less than 200mV for duration of 192 bit periods.
LOS is reset if the all of the following criteria are met:
24 or more ones are detected in 192-bit period with a detection threshold of 300mV measured
at RTIP and RRING.
During the 192 bits less than 100 consecutive zeros are detected.
8 consecutive zeros are not detected if B8ZS is set.
For long-haul mode, loss is detected if the received signal level is less than 30mV for duration of 192 bit periods.
LOS is reset if the all of the following criteria are met:
24 or more ones are detected in 192-bit period with a detection threshold of 40mV measured
at RTIP and RRING.
During the 192 bits less than 100 consecutive zeros are detected.
8 consecutive zeros are not detected if B8ZS is set.
5.5.6.2
ITU-T G.775 for E1 Modes
For short-haul mode, LOS is detected if the received signal level is less than 200mV for a continuous duration of
192 bit periods. LOS is reset if the receive signal level is greater than 300mV for a duration of 192 bit periods.
For long-haul mode, LOS is detected if the received signal level is less than 12mV for a continuous duration of 192
bit periods. LOS is reset if the receive signal level is greater than 20mV for a duration of 192 bit periods.
5.5.6.3
ETS 300 233 for E1 Modes
For short-haul mode, LOS is detected if the received signal level is less than 200mV for a continuous duration of
2048 (1ms) bit periods. LOS is reset if the receive signal level is greater than 300mV for a duration of 192 bit
periods.
For long-haul mode, LOS is detected if the received signal level is less than 12mV for a continuous duration of 192
bit periods. LOS is reset if the receive signal level is greater than 20mV for a duration of 192 bit periods.
5.5.7
AIS
Table 5-8 outlines the DS26334 AIS related specifications. Table 5-9 states the AIS functionality in the DS26334.
The registers related to the AIS detection are shown in Table 5-10.
