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.

• 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

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.

running a BERT. Three screens
are available.
These measurements are
independent of test pattern

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.
