    ATM2 OC48/STM16 IQ PIC with SFP (M40e Router)

    Image g002308.gif

    Software release


    • One OC48 port
    • Power requirement: 0.41 A @ 48 V ( 20 W)
    • Fine-grained queuing per logical interface
    • Conforms to ANSI T1.105-1991 and T1E1.2/93-020R1
    • Complies with ATM and SONET/SDH standards
    • Alarm and event counting and detection
    • Compatible with well-known ATM switches
    • ATM switch ID, which displays the switch IP address and local interface name of the adjacent Fore ATM switches

    Hardware features

    • ATM2 IQ 1-port OC48 PICs have one 3010 SAR for segmentation and reassembly into 53-byte ATM cells.
    • High-performance parsing of SONET/SDH frames
    • ASIC-based packet segmentation and reassembly (SAR) management and output port queuing
    • 64-MB SDRAM memory for ATM SAR
    • Packet buffering, Layer 2 parsing

    Software features

    • Multiprotocol Label Switching (MPLS) circuit cross-connect for leveraging ATM access networks
    • User-configurable virtual circuit (VC) and virtual path (VP) support
    • Support for idle cell or unassigned cell transmission
    • OAM fault management processes alarm indication signal (AIS), remote defect indication (RDI), and loop cells
    • Point-to-point and point-to-multipoint mode Layer 2 counters per VC and per VP
    • Local and remote loopback
    • ATM Inverse ARP, which enables routers to automatically learn the IP address of the router on the far end of an ATM PVC
    • Simple Network Management Protocol (SNMP):
      • Management Information Base (MIB) 2 (RFC 1213)
      • ATM MIB (RFC 1695)
      • SONET MIB
    • Unspecified bit rate (UBR), non-real-time variable bit rate (VBR), and constant bit rate (CBR) traffic shaping
    • Per-VC or per-VP traffic shaping
    • Support for F4 OAM cells
    • Support for 16-bit VCI range

    Cables and connectors


    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 error rate— signal fail (BERR-SF)
    • Loss of cell delineation (LOC)
    • 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:

      • Bit interleaved parity errors B1, B2, B3
      • 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 severely errored seconds (SES-LFE, SES-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)
