only the NET-> NT M4 status is available.

The status of each bit is represented by:

A *

: Indicates that this bit is set for 1. For example, in Figure 9,

fromNET->NT,theDEA,SCO,UOA,andAIBbitsaresetto1.

A _

: Indicates that this bit is set to 0. In Figure 9, from NET ->NT,

the ACT bit is set for 0.

Eachbitisdenedasfollows:

ACT: The Activation or start-up bit is set to 1 during the start up

sequence to communicate readiness for layer 1 communication.

DEA

: The Deactivation or turn-off bit is set to 0 by the LT to indicate

itsintentiontotakedownlayer1.

SCO

:Thisbitissetto1bytheLTtonotifytheNT1thattheLTwill

deactivatetheloopbetweencalls.

UOA

:TheUinterfaceOnlyActivationbitissetto1toindicateto

the NT1 to activate the S/T Interface or it is set for 0 to tell the

NT1 to deactivate the S/T Interface.

19SSxDSL-5M

AIB

: The Alarm Indication Bit is set to 1 to indicate good framing

and timing from the NT1 or it is set to 0 to indicate a loss of signal

of frame synchronization from the NT1 to LT.

PS1, PS2

:ThesearePowerStatus1and2bits.Theyareusedto

• 01:Primarypowerisoutofservice.

• 00:Primaryandsecondaryareoutofservice.

NTM

: The NT1 in Test Mode bit is set to 0 to indicate that the

NT1 is in a customer initiated test mode and may not be able to

respond to messages or eoc commands.

CSO

:TheColdStartOnlybitissetto1toindicatethattheNT1

hasaColdStartOnlytransceiver.

SAI

: The S/T Interface Activation Indicator bit is set to 1 to indicate

the S/T Interface is active or it is set to 0 to indicate no activity.

Use this for testing of the

running a BERT. Three screens

are available.

These measurements are

independent of test pattern

and pattern synchronization.

The first screen, shown on the

This screen is the logical

screen, it records all bit errors.

The measurements refer to

out of service testing with a

known test pattern. The test

set must have pattern sync to

measure bit errors; otherwise

it reports UAS.

Thefollowingisreported.

ET: Elapsed Time in Hours:Minutes:Seconds

RT: Remaining Time is Continuous in a untimed measurement.

RX: Received test pattern.

TX: Transmitted test pattern.

AS: Count of Available Seconds since the start of the test. A bit AS

is any bit error-free, bit errored, or bit severely errored second.

%AS: Percentage of Available Seconds since the start of the

test.
