This variable represents the loopback configuration of the DS3 interface. This variable is defined in the rfc1407 configuration table as dsx3LoopbackConfig, with slightly different values. ds3NoLoop (1) means that the interface is not in a loopback state. ds3CellLoop (2) means that cells that are processed by the receiving component are not written into the receive FIFO, but into the transmit FIFO for retransmission. ds3PayloadLoop (3) means that the receive signal is looped back for retransmission after it has passed through the port's reframing function. ds3DiagLoop (4) means that the transmit data stream is looped back to the receiver. ds3LineLoop (5) is only supported on series B and later netmods. ds3OtherLoop (6) means that the interface is in a loopback that is not defined here. Enumeration: 'ds3PayloadLoop': 3, 'ds3LineLoop': 5, 'ds3DiagLoop': 4, 'ds3OtherLoop': 6, 'ds3CellLoop': 2, 'ds3NoLoop': 1.

This variable indicates whether the information (48 octet payload) is being scrambled before transmitting. It should be set the same as the receiving side. Enumeration: 'scrambling': 1, 'noScrambling': 2.

This variable indicates the Line Status of the interface. A similar object is defined in the rfc1407 configuration table as dsx3LineStatus (the ds3RxFERF bit is not defined in rfc1407) . The variable contains loopback state information and failure state information. It is a bit map represented as a sum. The ds3NoAlarm should be set if and only if no other flag is set.

This variable indicates the types of cells that should be sent in case there is no real data to send. According to the ATM Forum, Unassigned cells should be sent (octet 1-3 are 0's, octet 4 is 0000xxx0, where x is 'don't care'). According to the CCITT specifications, Idle cells should be sent (everything is '0' except for the CLP bit which is '1'). By default, unassigned cells are transmitted is case there is no data to send. Enumeration: 'idle': 2, 'unassigned': 1.

This variable indicates the way ATM cells are constructed from the DS3 stream. ds3Hcs(1) indicates that the ATM cells are constructed upon the Header Check Sequence (HCS) inside the ATM cell header. ds3Plcp(2) indicates that the ATM cells are constructed from the DS3 PLCP (Physical Layer Convergence Protocol) bits. Enumeration: 'ds3Plcp': 2, 'ds3Hcs': 1.

This variable represents the length of the physical cable connected to the ds3 port. The user has to set this object to match the physical cable in order to get the netmod to receive the signal on the cable. The different values are: ds3LineLt225 (1) means the line is shorter than 225 ft, ds1LineGt225 (2) means the line length is greater than 220 ft. This value is not settable for Series A netmods and the value for these netmods is Gt225 Enumeration: 'ds3LineGt225': 2, 'ds3LineLt225': 1.

This variable represents the consecutive number of BAD/GOOD seconds to detect/clear an Excessive P-bit Parity Error Defect. The range of values it can take is between 2 and 10 inclusive.

This variable is a threshold for the number of P-bit Parity Errors per second and is used as a parameter to the Excessive P-bit Parity Error Defect. If the number of errors exceeds the threshold, the particular second is declared BAD, otherwise it is declared GOOD.

This variable controls whether declaration of an Excessive P-bit Parity Error Defect forces the port's operState to Down. Enumeration: 'disabled': 2, 'enabled': 1.

This is the exponent of 10 for the current signal fail bit error rate (BER) threshold for this port. The value -4, for example, represents a BER of 1E-4. This variable is only applicable when ds3BerErrorModel is set to errorModelRandom.

This is the exponent of 10 for the current signal degrade bit error rate (BER) threshold for this port. The value -8, for example, represents a BER of 1E-8. This variable is only applicable when ds3BerErrorModel is set to errorModelRandom.

This is the error distribution model to be used to identify signal degrade and signal fail conditions. errorModelRandom selects a random error distribution and declares signal conditions based on the thresholds set in ds3SigDegradeBer and ds3SigFailBer. errorModelBurst selects a burst error model and declares signal degrade conditions based on the thresholds set in ds3PErrThrSeconds and ds1PErrThrErrors. errorModelNone disables detection of signal conditions. Enumeration: 'errorModelNone': 0, 'errorModelBurst': 2, 'errorModelRandom': 1.

This value describes the current state of the port as determined through bit error rate analysis. Enumeration: 'berStateSigFail': 2, 'berStateOk': 0, 'berStateSigDegrade': 1.

The number of seconds in which Loss Of Frame (LOF) errors were detected by the PLCP (Physical Layer Convergence Protocol) receiver. LOF is declared when an Out-Of-Frame state persists for more than 1ms. LOF is removed when in-frame state persists for more than 12ms.

Number of BIP-8 (Bit Interleaved Parity - 8) error events. The BIP-8 is calculated over the Path Overhead field and the associated ATM cell of the previous frame. A BIP-N is a method of error monitoring. An N bit code is generated by the transmitting equipment in such a manner that the first bit of the code provides even parity over the first bit of all N-bit sequences in the previous VT SPE, the second bit provides even parity over the second bits of all N-bit sequences within the specified portion, etc.

Number of ATM Far End Block Error (FEBE) events.

The number of seconds in which Yellow alarm errors were detected by the PLCP (Physical Layer Convergence Protocol) receiver. Yellow alarm is asserted when 10 consecutive yellow signal bits are set to logical 1. Yellow signals are used to alert upstream terminals of a downstream failure in order to initiate trunk conditioning on the failure circuit.
