  • Page 3: Initial Turnup

    This provisioning part of the section describes provisioning options available with the MDR-8000 software application. Provisioning allows for the definition, editing, and storing of specific functions. The MDR-8000 provides the ability to provision equipment and facili- ties through a series of Windows™-based screens and messages. The Provisioning menu lists equipment and functions which may be provisioned.

  • Page 37 Note The 2-wire handset is transported over Audio 1 only. Note Audio provisioning is required only if 4-wire audio equipment (external equipment not part of the radio) is supplied and the external audio equipment is connected to audio port 1 J316 or audio port 2 J317 on the radio backplane. These provisionable 4-wire audio functions should not be confused with the 2-wire audio handset.
  • Page 38 Note DTMF allows you to dialup and ring other sites using the 2-wire hand- set. Only the ringing is detected. Communication over the handset is party-line. DTMF addressing is a local function not a network func- tion, therefore if one or more radios are assigned the same DTMF address, they will all ring when that address is dialed.

    CAUTION Possibility of Service Interruption RF flex coaxial cable requires special consideration. The electrical characteristics of the coax can be affected if it is accidentally twisted or bent. Provide mechanical support to prevent any weight or strain to the coax and connector when connecting or disconnecting equipment. Loosen the connectors at both ends of a coax section if one end must be moved even slightly.

    MODULE REPLACEMENT WARNING Possibility of Damage to Equipment Modules screwed to heat sink must be screwed securely before power is turned on. WARNING Possibility of Damage to Equipment Units with the electrostatic-sensitive (ESS) symbol contain ESS devices. Store these units in an antistatic container when not in use, and anyone handling a unit should observe antistatic precautions.
  • Page 64 CAUTION Possibility of Service Interruption Modules may be removed or installed with shelf power applied. How- ever, exercise reasonable care to prevent contacting adjacent modules. If clearances are narrow, consider setting the power supply to OFF while the module is being removed or replaced. (Before setting any switch to OFF, verify that traffic has been protected.) Before replacing any module, refer to Table 5-2 to determine the actions, other than phys- ical replacement, required.
