    MITSUBISHI ELECTRONICS AMERICA, INC. 3.2 Key Features All Mitsubishi MTs are easy to operate. The basic handset, for point-to-point calling, looks and operates like a cellular phone. There are three one-touch speed dial keys and 99 alphanumeric memory locations. The handset permits any key answering, displays received signal strength, and lets users enable special features from a menu of functions.
  • Page 9: Applications

    The list is not exhaustive: ♦ Telecommunications companies have purchased land mobile and transportable MTs for operating and maintaining land lines, both fiber optic and wire. Mitsubishi MTs can improve the efficiency of field units responding to fiber optic cable failure, saving a lot of money.

    MT operations. 5.1 Design Overview The Mitsubishi MTs operate under a blanket license from the FCC for MSAT Service under Part 25 (Satellite Communications) of its rules. This license, on file with the FCC (File No. 2823- DSE-P/L-93), does not require special MT identification tags for compliance.
  • Page 21: Signaling And Communications Channels

    Changes or modifications to the equipment that Mitsubishi Electronics does not expressly approve can void the authority to operate equipment within commercial and residential buildings. 5.2 Signaling and Communications Channels All Mitsubishi MTs access the MSAT network through six different special “channels”. The following table defines these channels: Channel From...
