Interface Identifier (dsx1LineIndex)

The unique identifier of a DS1 interface on a managed device.


Description (ifDescr)

The name of the interface.


Time Elapsed Seconds (dsx1TimeElapsed)

The number of seconds that elapsed since the beginning of the current error-measurement period.

Value range is from 0 to 899.

The type of circuit affects the number of bits per second that the circuit can reasonably carry, as well as the interpretation of the usage and error statistics.

Values are:

other (1)

dsx1ESF (2)

Extended SuperFrame DS1

dsx1D4 (3)

AT&T D4 format DS1

dsx1E1 (4)

CCITT Recommendation G.704 (Table 4a)

dsx1E1-CRC (5)

CCITT Recommendation G.704 (Table 4b)

dsx1E1-MF (6)

G.704 (Table 4a) with TS16 multiframing enabled

dsx1E1-CRC-MF (7)

Send Code Type (dsx1SendCode)

The type of code sent through the DS1 interface by the device.

Values are:

dsx1SendNoCode (1)

Sending looped or normal data.

dsx1SendLineCode (2)

Sending a request for a line loopback.

dsx1SendPayloadCode (3)

Sending a request for a payload loopback.

dsx1SendResetCode (4)

Sending a loopback termination request.

dsx1SendQRS (5)

Sending a quasi-random signal (QRS) test pattern.

dsx1Send511Pattern (6)

Circuit Identifier (dsx1CircuitIdentifier)

The transmission vendor's circuit identifier.

Value range is 0 to 255.


Loop back Configuration (dsx1LoopbackConfig)

The loopback configuration of the DS1 interface.

Values are:

dsx1NoLoop (1)

Not in the loopback state. A device that cannot perform a loopback on the interface always return this value.

dsx1PayloadLoop (2)

The received signal at this interface is looped through the device. Typically the received signal is looped back for retransmission after it passes through the device's framing function.

dsx1LineLoop (3)

The received signal at this interface does not go through the device (minimum penetration) but is looped back out.

dsx1OtherLoop (4)

Loopbacks that are not defined.


Signal Mode (dsx1SignalMode)

The signaling mode of the interface.

Values are:

none (1)

No bits are reserved for signaling on the channel.

robbedBit (2)

DS1 robbed bit signaling is in use.

bitOriented (3)

E1 channel associated signaling is in use.

messageOriented (4)

Common channel signaling is in use either on channel 16 of an E1 link or channel 24 or a DS1.

other (5)


Transmit Clock Source (dsx1TransmitClockSource)

The source of the transmit clock.

Values are:

loopTiming (1)

The recovered receive clock is used as the transmit clock.

localTiming (2)

A local clock source is used.

throughTiming (3)

The recovered receive clock from another interface is used as the transmit clock.


Facility Data Link (dsx1Fdl)

The use of the facilities data link (FDL).
