correcting any installation problems. This process assumes that the various units have been

installed in accordance with the system design plan.

1.1 Tools and Materials

The following tools and materials are required in order to complete the procedures in this

section:

• Portable spectrum analyzer and RF power meter

• DC voltmeter

• External RF and optical attenuators (if specified in system design plan)

• PC-type computer with Digivance Element Management System (EMS) Version 3.01

software installed

• Straight-through RS-232 DB-9 interface cable (accessory)

• Subscriber unit

•Pencil or pen

• Writing pad
