ATM2 OC12/STM4 IQ PICs

Software release

JUNOS 6.2 and later (Type 1 and Type 2)

Description	One or two OC12 ports Power requirement: 1-port: 0.41 A @ 48 V (20 W) 2-port: 0.52 A @ 48 V (25 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 OC12 PICs have one 3010 SAR for segmentation and reassembly into 53-byte ATM cells; ATM2 IQ 2-port OC12 PICs have dual 3010 SAR 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	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	Duplex SC/PC connector (Rx and Tx) Optical interface support—See Table 6
LEDs	One tricolor per port: Off—Not enabled Green—Online with no alarms or failures Amber—Online with alarms for remote failures Red—Active with a local alarm; router has detected a failure
