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."

DESCRIPTION
"This variable indicates the variety of DS3 C-bit
or E3 application implementing this interface. The
type of interface affects the interpretation of
the usage and error statistics. The rate of DS3
is 44.736 Mbps and E3 is 34.368 Mbps. The
dsx3ClearChannel value means that the C-bits are
not used except for sending/receiving AIS.
The values, in sequence, describe:

DESCRIPTION
"This variable describes the variety of Zero Code
Suppression used on this interface, which in turn
affects a number of its characteristics.
dsx3B3ZS and e3HDB3 refer to the use of specified
patterns of normal bits and bipolar violations
which are used to replace sequences of zero bits
of a specified length."

DESCRIPTION
"This variable indicates what type of code is
being sent across the DS3/E3 interface by the
device. (These are optional for E3 interfaces.)
Setting this variable causes the interface to
begin sending the code requested.
The values mean:
dsx3SendNoCode
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
within a DS3/E3 frame. The DS1/E1 is
indicated in dsx3Ds1ForRemoteLoop.
dsx3SendTestPattern
sending a test pattern."

"This variable contains the transmission vendor's

}
MAX-ACCESS read-write
STATUS current
DESCRIPTION
"This variable represents the desired loopback
configuration of the DS3/E3 interface.
The values mean:
dsx3NoLoop
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.
dsx3DualLoop
Both dsx1LineLoop and dsx1InwardLoop will be
active simultaneously."

dsx3LineStatus OBJECT-TYPE
SYNTAX INTEGER (1..4095)
MAX-ACCESS read-only
STATUS current
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.
The various bit positions are:
1 dsx3NoAlarm No alarm present
2 dsx3RcvRAIFailure Receiving Yellow/Remote
Alarm Indication
4 dsx3XmitRAIAlarm Transmitting Yellow/Remote
Alarm Indication
8 dsx3RcvAIS Receiving AIS failure state
16 dsx3XmitAIS Transmitting AIS
32 dsx3LOF Receiving LOF failure state
64 dsx3LOS Receiving LOS failure state
128 dsx3LoopbackState Looping the received signal
256 dsx3RcvTestCode Receiving a Test Pattern
512 dsx3OtherFailure any line status not defined

DESCRIPTION
"The source of Transmit Clock.
loopTiming indicates that the recovered receive clock

RFC 2496 DS3/E3 MIB January 1999
is used as the transmit clock.
localTiming indicates that a local clock source is used
or that an external clock is attached to the box
containing the interface.
throughTiming indicates that transmit clock is derived
from the recovered receive clock of another DS3
interface."

dsx3InvalidIntervals OBJECT-TYPE
SYNTAX INTEGER (0..96)
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The number of intervals in the range from 0 to
dsx3ValidIntervals for which no data is
available. This object will typically be zero
except in cases where the data for some intervals
are not available (e.g., in proxy situations)."
::= { dsx3ConfigEntry 12 }
dsx3LineLength OBJECT-TYPE
SYNTAX INTEGER (0..64000)
UNITS "meters"
MAX-ACCESS read-write

circuitry if it exists and can use this object to
adjust the line build out."
::= { dsx3ConfigEntry 13 }
dsx3LineStatusLastChange OBJECT-TYPE
SYNTAX TimeStamp
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The value of MIB II's sysUpTime object at the
time this DS3/E3 entered its current line status
state. If the current state was entered prior to
the last re-initialization of the proxy-agent,
then this object contains a zero value."

dsx3LoopbackStatus OBJECT-TYPE
SYNTAX INTEGER (1..127)
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"This variable represents the current state of the
loopback on the DS3 interface. It contains
information about loopbacks established by a
manager and remotely from the far end.
The dsx3LoopbackStatus is a bit map represented as
a sum, therefore is can represent multiple
loopbacks simultaneously.
