Chapter4 Configuration Tables and Fields
Interface Table
Two Segment Connections
Use the NMT to model ATM to Frame Relay interworking connections and ATM to Circuit Emulation
connections. Refer to Table 4-10 for information on modeling ATM and FR connections. Refer to
Table 4-11 for information on modeling ATM to CE connections.
Interface Table
The Interface Table contains topological and partition information about ports in the network.
The primary CWM source for the interface table is the PORT table. For the WANDL translation, the
Interface table is translated into optional parameters in either the BBLINK file or the DEMAND file,
which cross reference the NMT link or connection record based on the slot/port string.
Note The Interface table is called the Port table in the MS Excel and DBF interface.
The Interface Table fields are described in Table 4-12.

Bursty Traffic table
Type field: Enter ATM=FR or
FR=ATM.
Use ATM=FR when the ATM interface at Site1 interworks to a
Frame Relay interface at Site2. Use FR=ATM when a Frame Relay
interface at Site1 to interworks to an ATM interface at Site2.
The ATM end must support the specified traffic type (i.e., must be a
BPX or an IGX with 8.2.5 functionality).
All traffic values (MIR, PIR, FR=ATM) are given in kbps for ATM
traffic

ATM to CE
Bursty Traffic table
Type field: Enter ATM=CE or
CE=ATM.
Use ATM=CE when the ATM interface at Site1 interworks to a
Circuit Emulation interface at Site2. Use CE=ATM when the ATM
end is at Site 2 and CE is at Site 1.
All values (MIR,PIR) are in Kbps and the circuit should be
configured as a CBR where MIR equals PIR.
