Lucent Technologies 117A4 installation instructions Understanding Carriers

The outlet can also be tested using a voltmeter by taking the measurements as shown:

120Volts

Neutral Phase

If the outlet does not meet the electrical specifications for grounded outlets, your Multi-Line Digital Wireless (MDW) telephone may not operate properly.

!CAUTION:

If there is no current to the outlet or the voltages are not correct, the problem should be corrected by a qualified electrician.

Understanding Carriers

When you install more than one radio module in a single zone, you must mount the radio modules in a carrier, so that their signals will be synchronized. A carrier can hold up to six radio modules.

If you want to install more than six radio modules, you will need more than one carrier.

If any multiple-carrier installation, the leftmost carrier acts as the control carrier, and the remaining carriers act as expansion carriers, passing along the synchronization signal from the control carrier. Multiple carrier installations require that you use Model 117A3 or Model 117A4 carriers, or both.

The Model 117A3 and Model 117A4 carriers are similar in general appearance, but the installation procedure for the two models differs somewhat. A label on the left side of the carrier identifies the carrier model number.

Note: The illustrations in this manual depict PARTNER® system hardware; your hardware may differ from these illustrations.

The Model 117A4 carrier differs from the 117A3 in that it does not require that Slot 6 contain a radio module in order to pass the signal from the control carrier to the next carrier. It also does not have Power and Control/Expansion DIP switches to set. The 117A4 automatically adjusts its power level and senses whether it is being used as a control or an expansion carrier.
