Table 107 - Receive Line and Timer Interrupt Mask Register(Y45) (T1)
D4 Yellow Interrupt Mask. When unmasked this interrupt bit goes high whenever the D4
Yellow alarm code has been received. If 1 - masked, 0 - unmasked.
D4 Y48 Interrupt Mask. When unmasked this interrupt bit goes high whenever the D4
Yellow alarm code has been received for 48 msec. If 1 - masked, 0 - unmasked.
Secondary Yellow Interrupt Mask. When unmasked this interrupt bit goes high
whenever a Secondary Yellow alarm is received. If 1 - masked, 0 - unmasked.
ESF Yellow Interrupt Mask. When unmasked this interrupt bit goes high whenever a
ESF Yellow alarm is received. If 1 - masked, 0 - unmasked.
T1DM Yellow Interrupt Mask. When unmasked this interrupt bit goes high whenever a
TIDM Yellow alarm is received. If 1 - masked, 0 - unmasked.
not used
Bipolar Violation Interrupt Mask. When unmasked this interrupt bit goes high whenever
a bipolar violation (excluding B8ZS encoding) is encountered. If 1 - masked, 0 -
unmasked.
Pseudo Random Bit Sequence Error Interrupt Mask. When unmasked this interrupt bit
goes high upon detection of an error with a channel selected for PRBS testing. If 1 -
masked, 0 - unmasked.
Pulse Density Violation Interrupt Mask. When unmasked this interrupt bit goes high
whenever a sequence of 16 consecutive zeros is received on the line, or the incoming
pulse density is less than N ones in a time frame of 8(N+1) where N = 1 to 23. If 1 -
masked, 0 - unmasked.
Loop Code Enable Detected Interrupt Mask. When unmasked this interrupt bit goes high
whenever the loop up code has been detected on the line for a period of 48 milliseconds.
If 1 - masked, 0 - unmasked.
Loop Code Disable Detected Interrupt Mask. When unmasked this interrupt bit goes
high whenever the loop down code has been detected on the line for a period of 48
milliseconds. If 1 - masked, 0 - unmasked.
