Chapter 4 Configuration Tables and Fields

Links Table

For existing links, the Keep field should be set to the number of existing links, with the characteristics described in the record. The Links command displays existing links and possible links considered for the network design. The key fields in the link table are the site ends, the trunk type, and the keep field.

The primary CWM data source for the Links table is the link table. The WANDL translation for the link table is the bblink file. When translating from NMT to WANDL, a fixlink file identical to the bblink file is created. The Link Table fields are described in Table 4-3.
