1. About the FrameSaver SLV
1-2 September 2002 9128-A2-GB20-80
CSU/DSU-Specific Features
The following features only apply to the FrameSaver SLV 9126, 9126-II, and
9128-II CSU/DSUs:
T Two Interfaces. Provides two interfaces for traffic:
— Synchronous DTE port for user data
— Ethernet Interface for management data
T 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
collected before sending.
T LMI Protocol Support. Automatically detects and initializes the Local
Management Interface (LMI) protocol type on the user data port.
Router-Specific Features
The following features only apply to the FrameSaver SLV 9126-II router:
T T Device Migration. The FrameSaver SLV 9126-II Router can be converted to a
FrameSaver SLV 9126-II CSU/DSU with a firmware download.
T 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.
T 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.
