F5 OAM loopback
AIS
FERF
Cisco WAN switching Internal OAM
Interworking: ATM to Frame Relay connections
Connection Statistics
Round Trip Delay measurements incorporated into the ForeSight algorithm
Frame Based GCRA (FGCRA). This is an enhancement of the Generic Cell Rate Algorithm
IBS (Initial Burst Size)
cnfportq: 3 egress port queues are configurable CBR, VBR and VBR w/Foresight. (Queue Bin
numbers and algorithm types are NOT user selectable.)
BCM (Backward Congestion Messages)
ILMI and associated configuration options and statistics

End-to-end status updates (per FR/ATM interworking)
Annex G and associated configuration options and statistics
Priority Bumping is not supported across the interface shelves, but is supported across the routing
network.
Statistical Line Alarms per Software Functional Specification (that is, Bellcore standards).
