Bit

Name

Functional Description

D4YALMIM

(0)

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.

D4Y48IM

(0)

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.

SECYELIM

(0)

Secondary Yellow Interrupt Mask. When unmasked this interrupt bit goes high

whenever a Secondary Yellow alarm is received. If 1 - masked, 0 - unmasked.

ESFYELIM

(0)

ESF Yellow Interrupt Mask. When unmasked this interrupt bit goes high whenever a

ESF Yellow alarm is received. If 1 - masked, 0 - unmasked.

T1DMYIM

(0)

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

BPVIM

(0)

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.

PRBSIM

(0)

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.

7PDVIM

(0)

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.

6LLEDIM

(0)

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.

LLDDIM

(0)

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.
