The MIB module to describe DS1/E1 interface objects. This is
        an extension to the standard DS1/E1 MIB (RFC 2495).
        Unless mentioned, the DS1 interface refers to both 
        T1/E1 interfaces.
        Terminology ( Taken From RFC2495)
        AIS - Alarm Indication Signal
        LOS - Loss Of Signal
        LOF - Loss Of Frame
        Yellow Alarm - Far End LOF.
        Red Alarm    - Near End LOF.
        BPV - Bipolar Violation for an AMI-coded signal is the 
              occurrence of a pulse of the same polarity as the 
              previous pulse.
              A BPV error event for a B8ZS- or HDB3- coded signal
              is the occurrence of a pulse of the same polarity as 
              the previous pulse without being part of the zero
              substitution code. (See TR-TSV-000773 Section
        EXZ - An Excessive Zeroes error event for an AMI-coded
              signal is the occurrence of more than fifteen
              contiguous zeroes. For a B8ZS coded signal, 
              the defect occurs when more than seven contiguous 
              zeroes are detected.
        LCV - Line Coding Violation is the occurrence of either
              Bipolar Violation (BPV) or Excessive Zeroes (EXZ)
              error event.
        PCV - A Path Coding Violation error event is a frame
              synchronization bit error in the D4 and E1-noCRC formats,
              or a CRC or frame synch. bit error in the ESF and E1-CRC 
              formats. (Also known as CV-P; See T1.231 Section
        CS - A Controlled Slip is the replication or deletion of the 
             payload bits of a DS1 frame. (See T1.231 Section
             A Controlled Slip may be performed when there is a 
             difference between the timing of a synchronous 
             receiving terminal and the received signal.  A Controlled 
             Slip does not cause an Out of Frame defect.
        LES  - Line Errored Seconds. A LES is a second in which one or
               more LCV error events are detected. (See TR-TSV-000773 
        ES   - Errored Seconds (ES). For ESF and E1-CRC links an ES
               is a second with one or more PCV or one or more OOF 
               defects OR one or more CS events OR a detected AIS
               defect. (See TR-TSV-000773 Section
               For D4 and EN-noCRC links, the presence of BPVs also 
               triggers an ES.
               This is not incremented during an UAS.
        BES  - Bursty Errored Seconds. A BES is a second with fewer
               than 1 PCV error events, no Severely Errored Frame 
               defects and no detected incoming AIS defects. The
               CS are not included in this parameter.
               This is not incremented during an UAS. It applies to 
               ESF signals only.
        SES  - Severely Errored Seconds. A SES for ESF signals is a 
               second with 320 or more PCV error events OR one or 
               more OOF defects OR a detected AIS defect.
               (See TR-TSV-000773 Section
               For E1-CRC signals, a SES is a second with 832 or
               PCV error events OR one or more OOF defects.
               For E1-noCRC signals, a SES is a 2048 LCVs or more.
               For D4 signals, a SES is a count of one second
               intervals with Framing Error events, or an OOF defect,
               or 1544 LCVs or more.
        SEFS - Severely Errored Framing Second. An SESF is a second
               with one or more OOF defects OR a detected AIS defect.
               (Also known as SAS-P (SEF/AIS second).
               (See TR-TSV-000773 Section
        DM   - Degraded Minutes. A DM is one in which the estimated
               error rate exceeds 1E-6 but does not exceed 1E-3.
        UAS  - Unavailable Seconds. The UAS are calculated by counting
               the number of seconds that the interface is unavailable.
        CSS  - Controlled Slip Seconds. A CSS is a one-second interval 
               containing one or more controlled slips. This is not
               incremented during an Unavailable Second.
        LSES - Line Severely Errored Seconds is defined as a count of
               1-second intervals with 1544 Bipolar Violations plus
               Excessive Zeros event or one or more LOS defects.
        PSAS - Path SEF/AIS (PSAS) encountered.
