Image g001365.gif

Software release

JUNOS 4.1 and later

Description

One OC12 port

Power requirements: 0.43 A/48 V @ 20.8 W

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

Optical interface support—see Table 3

Hardware features

High-performance parsing of SONET/SDH frames

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

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

Duplex SC/PC connector (RX and TX)

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

Alarms, errors, and events
