Test Equipment Connection Charts
To use the following charts to identify necessary test equipment
connections, locate the communications system analyzer being used in
the
COMMUNICATIONS SYSTEM ANALYZER columns, and read down
the column. Where a dot appears in the column, connect one end of the
test cable to that connector. Follow the horizontal line to locate the end
connection(s), reading up the column to identify the appropriate
equipment and/or BTS connector.
IS–95A/B–only Test Equipment Connections
Table 3-21 depicts the interconnection requirements for currently
available test equipment supporting IS–95A/B only which meets
Motorola standards and is supported by the LMF.
