    Channelized T1 IQ PIC (M40e Router)

    Image g002310.gif

    Software release


    • Ten T1 ports
    • Power requirement: 0.15 A @ 48 V (7.2 W)
    • Fine-grained queuing per logical interface
    • Channelization: T1, FT1, NxDS0

    Hardware features

    • Data service unit (DSU) and channel service unit (CSU) functionality
    • Ports configurable as clear channel T1 interfaces with 1.544-Mbps connectivity
    • Framing: Superframe (SF or D4) and Extended Superframe (ESF)
    • Supports B8ZS (bipolar 8-zero substitution) and AMI (alternate mark inversion) line coding
    • Local, remote, and payload loopback testing
    • ANSI T1.403 loopback support:
      • Responds to embedded loopback commands upon receipt of an FDL command from remote end with loopup and loopdown at both line and payload level
      • Insertion of loopback commands enables remote CSU/NIU/Smartjack to enter loopback and loopdown at both the line and payload level (ANSI and Telcordia)
    • Inband loopback support:
      • Responds to inband loopback commands at both the line and payload level (ANSI and Telcordia)
      • Insertion of inband loopback commands at both the line and payload level (ANSI and Telcordia)
    • Clocking support of external (line) and internal
    • Buildout support of the following ranges:
      • 0 through 132 (Line buildout is from 1 through 132 feet)
      • 133 through 265 (Line buildout is from 133 through 265 feet)
      • 266 through 398 (Line buildout is from 266 through 398 feet)
      • 399 through 531 (Line buildout is from 399 through 531 feet)
      • 532 through 655 (Line buildout is from 532 through 655 feet)

    Software features

    • Quality of service (QoS) per channel: weighted round-robin (WRR), random early detection (RED), weighted random early detection (WRED)
    • SNMP: T1 MIB and DS0 MIB
    • Dynamic, arbitrary channel configuration
    • Full bit error rate test (BERT) patterns at T1 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

    • 120-ohm RJ-48C connector (female)


    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)
    • Bipolar violation (BPV)
    • Excessive zero (EXZ)
    • Line code violation (LCV)
    • Loss of frame (LOF)
    • Loss of signal (LOS)
    • Remote defect indication (RDI)

    Error detection:

    • Error seconds (ES)
    • Severely errored seconds (SES)
    • Severely errored frames (SEF)
    • Bit error event (BEE)

    Instrumentation (counters)

    • Layer 2 per-queue and per-channel packet and byte counters
    • 24–hour history or error counter updated at 15–minute intervals
