Hardkey assignments

The service order must indicate the function for each of the hard keys
shown in Figure 1-1. Hardkeys can be assigned as either line
appearances or feature keys. Some hardkeys have pre-assigned
functions depending upon the signalling type being used on the set.
Hardkey numbering and pre-assigned functions differ between
Functional signalling, MFT PVC0, and MFT PVC 1-consult
figure 2-1 for the scheme used at your installation.
