H Auto-Configuration. Provides the following automatic configuration features:
— Time Slot Discovery – For automatic configuration of all network DS0
assignments.
— Frame Relay Discovery – For automatic discovery of network DLCIs and
configuration of a user data port DLCIs, the PVC connection, and a
management PVC, which is multiplexed with user data DLCIs.
— LMI Protocol Discovery – For automatic configuration of the protocol
being used by the network.
— DLCI Deletion – For automatic removal of configuration of unused DLCIs
from the unit’s configuration and statistical databases.
— CIR Determination – For automatic recalculation of the committed rate
measurement interval (Tc) and excess burst size (Be) when a DLCI’s CIR
changes.
— Excess burst size (Be) and committed burst size (Bc) are recalculated
when Committed Burst Size Bc (Bits) is set to CIR. The committed rate
measurement interval (Tc) is recalculated when Committed Burst Size Bc
(Bits) is set to Other.
H Configurable FTP Transfer Rate. Allows you to control the transmit rate
used for downloading from the FrameSaver unit and uploading user history
statistics to an NMS (Network Management System) via the COM port
connection or a management PVC so the data can be transferred as a
background task using the standard File Transfer Protocol (FTP) over
extended periods of time using low bandwidth.
H Dual Flash Memory. Allows software upgrades while the unit is up and
running. Two software loads can be stored and implemented at the user’s
discretion.
H Multiplexed Management PVCs. Provides a method of multiplexing
management data with customer data transparently over a single PVC
(Permanent Virtual Circuit) when FrameSaver devices are at each end of the
circuit. This feature also makes it possible to run nondisruptive PVC tests.
H Maximum Number of PVCs and Management PVCs Supported.

H ATM VPI/VCI and DLCI Correlation. For networks with both ATM and frame
relay-access endpoints, allows the FrameSaver unit to report the originating
Virtual Path and Channel Identifier (VPI/VCI) in the far-end ATM-access
endpoint where the local DLCI is mapped. This occurs when the FrameSaver
unit is operating in frame relay mode.
