The DS1 Configuration dialog box enables you to configure the DSx interface.
Right-click on a DSx port, then select Configure > DS1 Configuration from the popup menu.
The following information appears:
Interface Identifier (dsx1LineIndex)
Time Elapsed Seconds (dsx1TimeElapsed)
Valid Intervals (dsx1ValidIntervals)
Circuit Identifier (dsx1CircuitIdentifier)
Loop back Configuration (dsx1LoopbackConfig)
Transmit Clock Source (dsx1TransmitClockSource)
Interface Line Status (dsx1LineStatus)
No Alarm Present (dsx1NoAlarm)
Near End LOF (dsx1XmtFarEndLOF)
NE Signal Loss (dsx1LossOfSignal)
NE Sending Tx LOMF (dsx1XmtFarEndLOMF)
Other Failures (dsx1OtherFailure)
Yellow Alarm (dsx1RcvFarEndLOF)
The unique identifier of a DS1 interface on a managed device.
The name of the interface.
The number of seconds that elapsed since the beginning of the current error-measurement period.
Value range is from 0 to 899.
The number of previous 15-minute intervals for which valid data was collected.
Value range is from 0 to 96.
The type of DS1 line implementing a circuit.
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) |
G.704 (Table 4b) with TS16 multiframing enabled |
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) |
Sending a 511 bit fixed test pattern. |
dsx1Send3in24Pattern (7) |
Sending a fixed test pattern of 3 bits set in 24. |
dsx1SendOtherTestPattern (8) |
Sending a test pattern other than those described by this object. |
The transmission vendor's circuit identifier.
Value range is 0 to 255.
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. |
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) |
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. |
The use of the facilities data link (FDL).
Values are:
other (1) |
A protocol other than the following is used. |
dsx1Ansi-T1-403 (2) |
FDL exchange recommended by ANSI. |
dsx1Att-54016 (4) |
ESF FDL exchanges. |
dsx1Fdl-none (8) |
Device does not use the FDL. |
The interface line status is derived from dsx1LineStatus. It is shown as a check box on the various error status messages appearing in the line. dsx1NoAlarm should be set only if no other flag is set.
No alarm is present.
Near end sending LOF indication.
Near end sending AIS.
Near end Loss Of Signal (LOS).
E1 TS16 AIS.
Near End Sending TS16 LOMF.
Any line status not defined here.
Far end LOF.
Far end sending AIS.
Near end LOF.
Near end is looped.
Far End Sending TS16 LOMF.
Near End detects a test code.
