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 | |
LEDs | 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
|

Error detection: - Bit interleaved parity errors B1, B2, B3
- Errored seconds (ES-S, ES-L, ES-P)
- Far-end bit errors, remote error indication—line
(REI-L), far-end line coding violations (CV-LFE)
- Far-end bit errors, remote error indication—path
(REI-P), far-end path coding violations (CV-PFE)
- Far-end errored seconds (ES-LFE, ES-PFE)
