HDual 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.
HMultiplexed 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.
HMaximum Number of PVCs and Management PVCs Supported.

HATM 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.
HFrame Relay Traffic Policing. Ensures proper alignment and correlation of
CIR (Committed Information Rate) values between the FrameSaver unit and
the frame relay interworking function on the network switch. When this
feature is enabled, the unit can enforce CIR and EIR (Excess Information
Rate), marking frames that exceed CIR as DE (Discard Eligible) using the
same method used by the switch, and discarding frames whose transmission
would cause committed burst size (Bc) and excess burst size (Be) to be
exceeded.
HRMON User History Performance Statistics via SNMP Polling. Provides
access to ESF line, physical interface, and basic frame relay performance
statistics by polling the FrameSaver unit using SNMP (Simple Network
Management Protocol). These statistics are available real-time via the
Enterprise MIB and historically as an RMON2 User History object.
HTrap Event Log. Shows the SNMP (Simple Network Management Protocol)
trap event log for the FrameSaver unit, with the most recent events first,
keeping a running total for all trap events stored, the amount of time since the
event was logged, plus a description of the trap.
HExtensive Testing Capability. Provides a variety of tests to identify
and diagnose device and network problems, including nondisruptive PVC
loopbacks and end-to-end connectivity. Tests can be commanded from the
unit’s menu-driven user interface or the OpenLane system.
These tests include V.54 or FT1-ANSI data channel loopback support so the
frame relay network service provider can perform a physical loopback from its
own switch without having to contact the local service provider for loopback
activation.
