1. About FrameSaver DSL Devices

FrameSaver DSL Features

Based upon the model ordered, or whether the device has been upgraded to Service Level Verifier (SLV) capability, FrameSaver DSL devices have the Diagnostic Feature Set or Advanced SLM Feature Set, each providing different levels of intelligence for monitoring, managing, and reporting performance of the device.

For features specific to the DSL CSU/DSU or router, see CSU/DSU-Specific

Features and Router-Specific Features.

CSU/DSU-Specific Features

The following features only apply to the DSL CSU/DSU:

￿

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

collected before sending.

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 DSL router:

 

Ethernet Interface. Supports user data and management traffic. An LED is

￿also provided to view the status of the interface.

￿

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.
