162
One OC12 port
Power requirement: 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
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
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)
Duplex SC/PC connector (RX and TX)
SONET/SDH OC12 fixed transceivers:
Multimode
Single-mode intermediate reach (IR-1)
Optical interface specifications—see
on page 42
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
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)
