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.
