    Image g001196.gif

    Software release

    Description

    • One OC12 port
    • Power requirement: 0.23 A @ 48 V (10.8 W)
    • 12 DS3 channels
    • Supports IP version 4 (IPv4) unicast and multicast as well as MPLS, Intermediate System-to-Intermediate System (IS-IS), Open Shortest Path First (OSPF), and Border Gateway Protocol (BGP)

    Hardware features

    • ASIC-based, high-performance throughput on all ports
    • Integrated DSU functionality with subrate and scrambling support for each DS3 channel
    • Class-of-service support for each DS3 channel
    • Dual-router SONET automatic protection switching (APS)
    • Rate policing on input for each DS3 channel
    • Rate shaping output for each DS3 channel
    • Packet buffering, Layer 2 parsing

    Software features

    • M13/C-bit parity encoding
    • Full instrumentation per DS3 channel
    • DS3 diagnostics and loopback control
    • DS3 alarm and event counting and detection
    • DS3 Far-end Alarm and Control (FEAC) channel support
    • Encapsulations:
      • Circuit cross-connect (CCC)
      • Translational cross-connect (TCC)
      • Frame Relay
      • High-Level Data Link Control (HDLC)
      • Point-to-Point Protocol (PPP)

    Cables and connectors

    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 (AIS-L, AIS-P)
    • BERT functionality (you can configure one DS3 channel in BERT mode and configure the remaining channels to transmit and receive normal traffic)
    • Bit error rate signal degrade (BERR-SD), Bit error rate signal fail (BERR-SF)
    • Bit interleaved parity errors B1, B2, B3 (CV-S, CV-L, CV-P)
    • Equipment failure (Does not affect service)
    • Errored seconds (ES-S, ES-L, ES-P), far-end bit errors REI-L, REI-P (CV-LFE, CV-PFE), far-end block error (FEBE), far-end errored seconds (ES-LFE, ES-PFE), far-end severely errored seconds (SES-LFE, SES-PFE), far-end unavailable seconds (UAS-LFE, UAS-PFE)
    • Frame error
    • Idle code, Idle received
    • Loss of frame (LOF), Loss of pointer (LOP-P), Loss of signal (LOS)
    • Out of frame (OOF)
    • Payload Mismatch (PLM-P), payload unequipped (UNEQ-P)
    • Parity bit (P-bit) disagreements
    • Path parity error
    • Remote defect indication (RDI-L, RDI-P)
    • 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)
    • Yellow alarm bit (X-bit) disagreements
