SYNTAX InterfaceIndex
MAX-ACCESS read-only -- read-only since originally an
-- SMIv1 index
STATUS current
DESCRIPTION
"This object should be made equal to ifIndex. The
next paragraph describes its previous usage.
Making the object equal to ifIndex allows proper
use of ifStackTable.
Previously, this object was the identifier of a
DS3/E3 Interface on a managed device. If there is
an ifEntry that is directly associated with this
and only this DS3/E3 interface, it should have the
same value as ifIndex. Otherwise, number the
dsx3LineIndices with an unique identifier
following the rules of choosing a number that is
greater than ifNumber and numbering the inside
interfaces (e.g., equipment side) with even
numbers and outside interfaces (e.g., network side)
with odd numbers."

MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The number of seconds that have elapsed since the

an adjustment in the system’s time-of-day clock,
the current interval exceeds the maximum value,
the agent will return the maximum value."

DESCRIPTION
"The number of previous near end intervals for
which data was collected. The value will be 96
unless the interface was brought online within the
last 24 hours, in which case the value will be the
number of complete 15 minute near end intervals
since the interface has been online. In the case
where the agent is a proxy, it is possible that
some intervals are unavailable. In this case,
this interval is the maximum interval number for
which data is available."

sending looped or normal data
dsx3SendLineCode
sending a request for a line loopback
dsx3SendPayloadCode
sending a request for a payload loopback
(i.e., all DS1/E1s in a DS3/E3 frame)
dsx3SendResetCode
sending a loopback deactivation request
dsx3SendDS1LoopCode
requesting to loopback a particular DS1/E1

"This variable represents the desired loopback

Not in the loopback state. A device that is
not capable of performing a loopback on
the interface shall always return this as
its value.
dsx3PayloadLoop
The received signal at this interface is looped
through the device. Typically the received signal
is looped back for retransmission after it has
passed through the device’s framing function.
dsx3LineLoop
The received signal at this interface does not
go through the device (minimum penetration) but
is looped back out.
dsx3OtherLoop
Loopbacks that are not defined here.
dsx3InwardLoop
The sent signal at this interface is looped back
through the device.

DESCRIPTION
"This variable indicates the Line Status of the
interface. It contains loopback state information
and failure state information. The dsx3LineStatus
is a bit map represented as a sum, therefore, it
can represent multiple failures and a loopback
(see dsx3LoopbackConfig object for the type of
loopback) simultaneously. The dsx3NoAlarm must be
set if and only if no other flag is set.
If the dsx3loopbackState bit is set, the loopback
in effect can be determined from the
dsx3loopbackConfig object.
