The DualMode 800 Enclosure is basically operated by the Digital Multiplex
Switch - Mobile Telephone Exchange (DMS-MTX*). It can also be operated
by a service personnel at the cell site through an interface terminal to perform
some operational functions and tests. This manual provides information on
how to operate the cell site equipment and perform maintenance tasks and
operational tests at the cell site. However, some of the tests may involve
activities at the MTX switch. For details of the MTX activities, refer to the
appropriate DMS-MTX manuals.
To operate and test cell site equipment, an interface terminal and some other
test equipment are required. This chapter provides a list of recommended test
equipment and precautions to be aware of when performing any tasks at the
cell site.
Test equipment
It is assumed that the operator is familiar with the test equipment used in the
test procedures. The following test equipment is recommended for
performing the required tests. Any functionally equivalent unit may be used
in its place. Double shielded coaxial cables are recommended for use between
