2.5 Selecting Channels
Before beginning to install the hardware, identify the various channels on which the system will operate:
• DCCH channel
• Boosted DCCH channel
• Donor DTC RF channels (primary and neighboring)
• Boosted DTC RF channels
• Directed retry channels
Make note of all selected channels. They will be entered as system parameters during installation
(Volume 1, Section 4). DCCH channel parameters are listed under the DCCH Channels Menu, shown
here with all available selections. Refer to this menu for sections 2.5.1 through 2.5.5.
(NOTE: SETTING OF THE BOOSTED DCCH HAS BEEN MOVED FROM THIS MENU TO THE RF BOARDS MENU.
SHOULDN’T THE DONOR AND BOOSTED DCCH CHANNEL ASSGINEMENTS BE IN THE SAME MENU?)
2.5.1 Identifying the Donor DCCH Channel
The donor DCCH channel (selection I, Control Channels Menu) is the control channel of the
primary cell site with which the EAC-2100 will communicate.
• When the booster is adjacent to a single cell site, the DCCH channel of that cell site is
the donor DCCH channel.
• When the booster is adjacent to several cell sites, the DCCH channel of the cell site with
the most unused channels should be chosen. (This cell is then referred to as the primary
donor cell.) Signals from multiple (primary and secondary) donors must be balanced at the
EAC-2100 donor antenna be to within the handoff hysteresis window that is programmed
into the donor cells. Otherwise, unwanted hand-offs by the cellular system may occur,
thereby causing dropped calls.
