TEXTUAL-CONVENTION

The Sonet APS line failure code - this is the failure encountered by the APS line. csApsChannelMismatch: Transmitted K1 byte and received K2 byte do not match. csApsProtectionByteFail: It could mean either K1 byte with invalid type of switch request bits was received, or, priority of received K1 byte is lower than the transmitted K1 byte. csApsFEProtectionFailure: Remote end error detected. csApsModeMismatch: APS architecture mode mismatch.

TEXTUAL-CONVENTION

The indication of the APS line failure status with a bit map representing multiple failures. noApsLineFailure bit indicates current failure status. This bit should be set ONLY if no other bit is set. csApsChannelMismatchBit is set when the APS line is in csApsChannelMismatch. csApsProtectionByteFailBit is set when the APS line is in csApsProtectionByteFail failure code. csApsFEProtectionFailureBit is set when the APS line is in csApsFEProtectionFailure. csApsModeMismatchBit is set when the APS line is in csApsModeMismatch.

TEXTUAL-CONVENTION

The reason why APS switch happened. When the working line on one end fails, its other end is told to do an APS switch. The following options in the increasing order of priority indicate what type of switch request it is. csApsRevertive : Switch back to working line after the Wait-to-Restore interval is over, and failures are cleared. It is the lowest priority. csApsManual : Manual switch causes APS switch unless a request of equal or higher priority is in effect. csApsSignalDefectLow : Switch happened because threshold for 'csApsSigFaultBER' was exceeded. csApsSignalDefectHigh : Same as above, but higher priority. csApsSignalFailureLow : Switch happened because threshold for 'csApsSigDegradeBER' was exceeded. csApsSignalFailureHigh : Same as above, but higher priority. csApsForceSwitch : Forced switch forces hardware to switch the active line even if the other line (could be working line or protection line) is in alarm. csApsLockOut : This is the highest priority switch. This will override all other requests. csApsNoSwitch : This is a state when no switch happens.

The SONET/SDH configuration table. This table has objects for configuring sonet lines.

OBJECT-TYPE

An entry in the table. There is an entry for each SONET line in the table. Entries are automatically created for an ifType value of sonet(39). 'ifAdminStatus' from the ifTable must be used to enable or disable a line. A line is in disabled(down) state unless provisioned 'up' using 'ifAdminStatus'.

This object specifies the desired loopback mode configuration of the SONET line. The possible values of this objects are follows: noLoopback : Not in the loopback state. lineLocal : The signal transmitted from this interface is connected to the associated incoming receiver. This ensures that the SONET frame transmitted from the interface is received back at the interface. lineRemote : The signal received at the interface is looped back out to the associated transmitter. This ensures that the remote equipment that originated the signal receives it back. The signal may undergo degradation as a result of the characteristics of the transmission medium.

OBJECT-TYPE

This table contains objects to configure APS (Automatic Protection Switching) feature in a SONET Line. APS is the ability to configure a pair of SONET lines for redundancy so that the hardware will automatically switch the active line from working line to the protection line or vice versa, within 60ms, when the active line fails.

OBJECT-TYPE

An entry is created when an APS pair is configured. To create an entry, the following objects must be specified: csApsWorkingIndex, csApsProtectionIndex, csApsEnable, csApsArchMode. The protection line must not be active, i.e, ifAdminStatus must be 'down', while configuring APS. An entry is created by setting the value of 'csApsEnable' to csApsEnabled (2) and deleted by setting it to csApsDisabled (1). Once a line is configured as working line or protection line, it remains in that role until APS is disabled on that sonet line pair. It remains in the working/protection role even after the card is reset.

OBJECT-TYPE

When a pair of APS lines is configured, one line has to be the working line, which is the primary line, and the other has to be the protection line, which is the backup line. This object refers to the working line in the APS pair. For G.783 AnnexB, this index refers to Working Section 1.

OBJECT-TYPE

The protection line indicates that it will become the active line when an APS switch occurs (APS switch could occur because of a failure on the working line). For G.783 AnnexB, This index refers to Working Section 2.

OBJECT-TYPE

This object is used to enable or disable the APS feature on the working/protection line pairs. When enabled, the hardware will automatically switch the active line from the working line to the protection line within 60ms, or vice versa.

OBJECT-TYPE

This object is used to configure APS architecture mode on the working/protection line pairs. All of the following are supported on single slot. oneToOne(2) is not supported across 2 slots,i.e. the working and protection slot numbers must be the same in oneToOne(2). onePlusOne : This can be supported on the same card and across 2 cards. This mode means that the transmit and receive signals go only over the active line(which could be working or protection line). (straight cable implied) oneToOne : This is supported only on the same card This mode means that the transmit and receive signals go over the working and protection lines. (straight cable implied) anexBOnePlusOne : This can be supported on the same card and across 2 cards. This mode is like the onePlusOne mode, except that the 'csApsDirection' can only be bi-directional. (straight cable implied) ycableOnePlusOneNok1k2: With Y-cable ignore K1K2 bytes. This mode is the Y-cable redundancy mode. straightOnePlusOneNok1k2 : With straight cable, ignore K1K2 bytes. This mode is like onePlusOne, but with K1, K2 bytes ignored.

OBJECT-TYPE

OBJECT-TYPE

This object contains the Bit Error Rate threshold for Signal Degrade detection on the working line. Once this threshold is exceeded, an APS switch will occur. This value is 10 to -n where n is between 5 and 9.

OBJECT-TYPE

This object contains interval in minutes to wait before attempting to switch back to working line. Not applicable if the line is configured in non-revertive mode, i.e. protection line will continue to be active, even if failures on the working line are cleared. The framer clears the signal-fault and signal-degrade when APS switch occurs. Please refer to 'csApsRevertive' for description of non-revertive.

OBJECT-TYPE

This object is used to configure the switching direction which this APS line supports. Unidirectional : APS switch only in one direction. Bidirectional : APS switch in both ends of the line.

OBJECT-TYPE

This object is used to configure the APS revertive or nonrevertive option. revertive : Will switch the working line back to active state after the Wait-To-restore interval has expired and the working line Signal-Fault/Signal-Degrade has been cleared. Please refer to 'csApsWaitToRestore' for description of Wait-To-Restore interval. nonrevertive : The protection line continues to be the active line, The active line does not switch to the working line.

OBJECT-TYPE

OBJECT-TYPE

This object shows the actual APS architecture mode that is implemented on the Near End terminal.
