If the Controller in an existing EAC-2000 installation is being upgraded to the 19-
20001-1 version, then many of the parameters programmed into the existing system
will also need to be copied to the new controller.  To assist in this operation a blank
Parameter Worksheet is included in the appendix.  This provides a place to list the
current setup parameters so that they can be entered as the new digital-capable
Controller is installed.   The highlighted entries on the Parameter Worksheet are
digital-specific and will entered later.

Information on connecting a local terminal to the EAC-2000D is contained in Section
4.4 of Volume 1 of the EAC-2000 Manual.

The digital donor control channel is the IS-136 control channel of the primary cell
site with which the EAC-2000 will communicate.  It can be used in conjunction with
an Analog Donor Control channel where both analog only and IS-136 mobiles are to
be served in the boosted coverage area.

• When the booster is adjacent to a single cell site, the control channel(s) of that
cell site is(are) the donor control channel(s).

• When the booster is adjacent to several cell sites, the control channel(s) of the
cell site with the most unused channels should be chosen.  (This cell is then referred
to as the primary donor cell.)  More than one cell site being received by a donor
antenna can result in unwanted hand-offs by the cellular system, causing dropped
calls.  Therefore the donor antenna should be positioned to favor the desired donor
cell site.  As in the analog case, the reverse-path signal level received from the EAC-
2000 by the adjacent cell sites must be less than the signal level received by the
selected donor site.  Usually a 10 dB margin is sufficient.

• When both analog and digital donor channels are selected, it is best if they are
both from the same donor cell site as that makes positioning of the donor antenna
easier.
