Software release

• JUNOS 6.0 and later

Description

• Two OC3 ports
• Power requirement: 0.41 A @ 48 V (20 W)
• Intelligent queuing (IQ) PICs support fine-grained queuing per logical interface
• Conforms to ANSI T1.105-1991 and T1E1.2/93-020R1
• ATM and SONET/SDH 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

• Single 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

Software features

• Circuit cross-connect (CCC) 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 indicator (RDI) cells, 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 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)
• 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

• Duplex SC/PC connector (RX and TX)
• Optical interface support—See Table 2

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

• Loss of cell delineation (LOC), loss of frame (LOF), loss of pointer (LOP-P), loss of signal (LOS)
• Payload mismatch (PLM-P), payload unequipped (UNEQ-P)
• 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)
