AUTO_MYEL
Automatic Manual Transmit Multiframe Yellow Alarm—Applicable to E1 modes only.
AUTO_MYEL /TMYEL
Automatic mode sends Multiframe Yellow Alarm for the duration of a receive loss of CAS
alignment [SRED; addr 049]. Manual mode sends Y16 Multiframe Yellow Alarm as long as
TMYEL is active.
INS_MYEL
Automatic Manual Transmit Yellow Alarm—Automatic mode sends a Yellow Alarm for the
AUTO_YEL/TYEL
duration of a receive loss of frame alignment [FRED; addr 049]. Manual mode sends the alarm
as long as TYEL is active and Yellow Alarm insertion [INS_YEL; addr 072] is enabled.
INS_YEL
NOTE(S):
(1) When Inactive, time slot data passes through transmitter without modification.
2. To transmit T1DM Yellow Alarm (Y24), the processor must program TDL1,
TDL2, or TSLIP buffer to transmit Y-bit output in time slot 24.
