■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
Software features
■Duplex SC/PC connector (RX and TX)
■Optical interface support—See Table 6 on page 18
Cables and connectors
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
LEDs
