ATM2 OC3/STM1 IQ PIC (M7i Router)
• Junos OS Release 6.0 and later Software release
• 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
Description
• 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
• 64 MB SDRAM memory for ATM SAR
• Packet buffering, Layer 2 parsing
Hardware 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
