ATM DS3 EOL PIC (M10i Router)

 

Software release

  • Junos OS Release 6.1 and later

  • End-of-life (see notification PSN-2003-10-018)

Description

  • Four DS3 ports

  • Power requirement: 0.39 A @ 48 V (19 W)

  • Conforms to ANSI T1.105-1991 and T1E1.2/93-020R1

  • Asynchronous Transfer Mode (ATM) standards compliant

  • 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

  • OAM fault management processes alarm indication signal (AIS) and remote defect indicator (RDI) cells

  • ASIC-based packet segmentation and reassembly (SAR) management and output port queuing

  • 16-MB SDRAM memory for ATM SAR

  • Packet buffering, Layer 2 parsing

  • Configurable framing options:

    • C-bit with ATM direct mapping

    • C-bit with PLCP framing (default)

    • M23 ATM direct mapping

    • M23 with PLCP framing

Software features

  • Multiprotocol Label Switching (MPLS) circuit cross-connect (CCC) for leveraging ATM access networks

  • Support for user-configurable virtual circuits (VC) and virtual paths (VP)

  • ATM Inverse Address Resolution Protocol (ARP), which enables routers to automatically learn the IP address of the router on the far end of an ATM permanent virtual circuit (PVC)

  • Unspecified bit rate (UBR) traffic shaping

  • Fine-grained variable bit rate (VBR) traffic shaping

  • Outbound PIC queues cells on a per-VC basis

  • Encapsulations—AAL5 subnetwork attachment point (SNAP)

Cables and connectors

  • 10-ft (3.05-m) posilock SMB to BNC

  • Four pairs of RX and TX coaxial cables

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)

  • Far-end block error (FEBE)

  • Frame error

  • Idle code

  • Idle received

  • Local and remote loopback

  • Loss of signal (LOS)

  • Out of frame (OOF)

  • Path parity error

  • Yellow alarm
