Installing Applications

Considerations

Applications that use mode codes must be connected to integrated VMI ports. Applications (such as MERLIN Attendant) that do not use mode codes connect to generic VMI ports. The tip/ring ports on 012 basic telephone modules are programmed to be either “generic VMI” or “integrated VMI.”

A VMS requires a certain number of touch-tone receivers (TTRs), depending on the number of VMS ports (see Table 8-1). TTRs are supplied by the following modules: 008 OPT, 012, 400, and 400 GS/LS/TTR. However, the VMS applications are not supported on the 008 OPT module.
