Planning the installation before actually installing the system is advisable.
Advanced planning minimizes installation time, cost and disruption of the
customer business activities.
2.1 Precautionary Information
2.2 Surveying the Customer Site
In most cases, a survey of the customer site is necessary to
determine the proper placement of the Main Distribution Frame
(MDF), the exact dimensions of the area selected for the MDF,
cabling requirements, and possible Intermediate Distribution Frame
(IDF) locations.
The information obtained at the customer site can permit the
installer to partially assemble the MDF before installing at the
customer premise. This can help reduce the time spent installing at
the customer site to reduce their downtime.
Observe the following warnings during installation.
• Never install telephone wiring during a lightning storm.
• Never install telephone jacks in wet locations unless the
jack is specifically designed for wet locations.
• Never touch uninsulated telephone wires or terminals
unless the telephone line is disconnected at the network
interface.
• Use caution when installing or modifying telephone lines.
