Two Interfaces. Provides two interfaces for traffic:

—Synchronous DTE port for user data

—Ethernet Interface for management data

Upstream Pipelining. Provides pipelining capability into the Wide Area Network (WAN) for reduced latency, where groups of bytes are transmitted as soon as they are received, rather than waiting for the entire frame to be

Tcollected before sending.

LMI Protocol Support. Automatically detects and initializes the Local Management Interface (LMI) protocol type on the user data port.

Device Migration. The FrameSaver SLV 9126-II Router can be converted to a

FrameSaver SLV 9126-II CSU/DSU with a firmware download.

In-Band Router Management. Permits the router to be managed via customer data PVCs and EDLCIs by assigning an IP address for router management that is different from the IP address generally used for the network interface.

Inverse ARP for User Data. Provides Inverse ARP (Address Resolution Protocol) support for user data, as well as management data. The router responds to Inverse ARP requests, and can acquire the IP address of a FrameSaver device at the far end of a customer PVC. ARP information is retained for both customer data and management data.
