Image g001848.gif

Software release

JUNOS 6.2 and later (Type 1)

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

64 MB SDRAM memory for ATM SAR

Packet buffering, Layer 2 parsing

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 5

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

Alarm indication signal (AIS-L, AIS-P)

Bit error rate signal degrade (BERR-SD), bit error rate signal fail (BERR-SF)

Bit interleaved parity errors B1, B2, B3

Errored seconds (ES-S, ES-L, ES-P), far-end bit errors REI-L, REI-P (CV-LFE, CV-PFE), far-end errored seconds (ES-LFE, ES-PFE), far-end severely errored seconds (SES-LFE, SES-PFE), far-end unavailable seconds (UAS-LFE, UAS-PFE)

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)
