CABLING REQUIREMENTS

This chapter addresses many aspects of installing optical fiber cabling to support the CoreBuilder 7000 family ATM switch environment. It will also deal with modem cables and Ethernet and control cables for management. The following topics are covered:

Installing new cabling

ATM cabling requirements

Ethernet cabling requirements

Installing New

Cabling

Cable Labeling and Record Keeping

If you are installing new cabling, follow these guidelines:

3Com recommends that you use a cabling system plan, such as AT&T's Premises Distribution System (PDS) or the IBM Cabling System.

Determine how many CoreBuilder 7000 units are going to be supported by each wiring closet, and how many downlink connections from these CoreBuilder 7000 units are planned.

Locate wiring closets to enable connections to the different floors.

To simplify installation of the network and to aid in troubleshooting, install a telephone in each wiring closet for communication between

￿wiring closets, work areas, and other locations.

Include all linear distances (vertical rises, etc.) in the cable plan so that all cables - from wiring closet to desk and to other wiring closets - are under their respective maximum lengths.

A reliable cable labelling and record keeping system is essential when planning any network installation. A good cable labelling system provides enough information for you to locate the opposite end of any cable. Maintaining accurate records helps you to: 1) relocate devices easily,

2) make changes quickly, and 3) isolate faults in the distribution system.
