Name

Functional Description

7 - 0 RxEBC7 -0 Receive Eighth Bit Count. The 8

least significant bit of a counter

that indicates the number of one

eighth bit times there are between

the ST-BUS frame pulse and

receive frame pulse (RxFP).The

accuracy of the this measurement

approximately

+ 1/16

(one

sixteenth) of a bit.

Bit

Name

Functional Description

JACS

Jitter Attenuated Clock Slow. If

one it indicates that the dejittered

clock period is increased by 1/16 UI.

If zero the clock is at normal speed.

JACF

Jitter Attenuated Clock Fast. If

one it indicates that the dejittered

clock period is decreased by 1/16

UI. If zero the clock is at normal

speed.

JAE

Jitter Attenuator FIFO Empty. If

one it indicates that the JA FIFO is

empty.

JAF4

Jitter Attenuator FIFO with 4 Full

Locations. If one it indicates that

the JA FIFO has at least 4 full

locations.

JAFC

Jitter Attenuator Center Full. If

one it indicates that the JA FIFO is

at least half full.

JAE4

Jitter Attenuator FIFO with 4

Empty

Locations.

one

indicates that the JA FIFO has at

most 4 empty locations.

JAF

Jitter Attenuator FIFO Full. If one

it indicates that the JA FIFO is full.

Bit

Name

Functional Description

7LL

Long Loop. This bit is one when

the line signal has an amplitude so

attenuated as to require substantial

equalization for data recovery.

6ML

Medium Loop. This bit is one when

the line signal has an amplitude so

attenuated

require

some

equalization for data recovery.

5SL

Short Loop. This bit is one when

the line signal has an amplitude with

minimal attenuation.

LLOS

LIU Loss of Signal Indication.

This bit will be one when the

received signal amplitude is more

than 20 dB below the nominal value

for a period of at least 1 msec. This

bit will be zero for normal operation.
