    Image g003096.gif

    Software release

    Description

    • One STM1 port
    • Power requirement: 0.39 A @ 48 V (18.6 W)
    • Fine-grained queuing per logical interface
    • Channelization: STM1c, fractional E1, framed and unframed DS0

    Hardware features

    • Packet buffering, Layer 2 parsing
    • Local and remote loopback testing

    Software features

    • Quality of service (QoS) per channel: weighted round-robin (WRR), random early detection (RED), weighted random early detection (WRED)
    • SNMP: SONET/SDH MIB, T1/E1 MIB
    • Dynamic, arbitrary channel configuration
    • Full bit error rate test (BERT) patterns at E1 and DS0 levels
    • Encapsulations:
      • High-Level Data Link Control (HDLC)
      • Frame Relay
      • Circuit cross-connect (CCC)
      • Translational cross-connect (TCC)
      • Point-to-Point Protocol (PPP)

    Cables and connectors

    • Duplex SC/PC connector (Rx and Tx); single-mode intermediate-reach fiber

    LEDs

    One tricolor per port:

    • Off—Not enabled
    • Green—Online with no alarms or failures
    • Yellow—Online with alarms for remote failures
    • Red—Active with a local alarm; router has detected a failure

    Alarms, errors, and events

    • Alarm indication signal—line (AIS-L)
    • Alarm indication signal—path (AIS-P)
    • Bit error rate—signal degrade (BERR-SD)

    • Bit interleaved parity errors B1, B2, B3 (CV-S, CV-L, CV-P)
    • Loss of frame (LOF)
    • Loss of pointer (LOP-P)
    • Loss of signal (LOS)
    • Payload mismatch (PLM-P)
    • Payload unequipped (unequipped STS at path level) (UNEQ-P)
    • Remote defect indication—line (RDI-L)
    • Remote defect indication—path (RDI-P)

    Error detection:

    • Errored seconds (ES-S, ES-L, ES-P)
    • Far-end bit errors, remote error indication—line (REI-L), far-end line coding violations (CV-LFE)
    • Far-end bit errors, remote error indication—path (REI-P), far-end path coding violations (CV-PFE)
    • Far-end errored seconds (ES-LFE, ES-PFE)

    • Far-end unavailable seconds (UAS-LFE, UAS-PFE)
    • Severely errored framing (SEF)
    • Severely errored framing seconds (SEFS-S)
    • Severely errored seconds (SES-S, SES-L, SES-P)
    • Unavailable seconds (UAS-L, UAS-P)

    Instrumentation (counters)
