ATF Connection Criteria

ATF connections are allowed between any combination of ATM and Frame Relay UNI and NNI ports.
Virtual circuit connections are allowed. Virtual path connections are not.
Release 9.3.0, Part Number 78-10674-01 Rev. D0, July 2001
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
Loopback functions: tstdly, tstconseg, addrmtlp, addloclp
Selftest/ Background tests
OAM flows: AIS, FERF, OAM loopback
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).
Programmable Opti Class: although 4 connection classes are supported: CBR, VBR, VBR with
Foresight, ATF, and ATF with ForeSight. Configuration of egress port queues and BNI trunk queues
for these connection classes is available.
Port loopback tstport
Test tstcon is not supported at BPX switch endpoints.
Gateway terminated inter-domain connections
