MULTI-DROP NETWORK

The multi-drop network involves two or more, two-pair cable segments. Each

cable segment includes a Xmt and Rcv cable pair. The ends of the cable are

connected to a single modem. These modems are also referred to as the near-

and far-end modems. The master modem is located at the near end. The far

end is equipped with a slave modem. The intersection of two cable segments

forms a drop point. A slave modem can be connected to the network at each

drop point. Figure 4 on page 11 illustrates a typical multi-drop network.

The proper setup configuration for a multi-drop network is as follows:

• The Xmt and Rcv Terminations for the near- and far-end modems must be

set to On.

• The Xmt and Rcv Terminations for each modem at a drop point must be set

to Off.

NOTE: A multi-drop network is limited to no more than eight modems.
