4. Setting Up for Initial Operation

EAC-2100 Manual: (Draft, 02/01) Page 4-22

4.6.8 Programming Alarms and Thresholds (Continued)

Critical alarms will cause the EAC-2100 to automatically dial an alarm

telephone number when the Auto-Dial feature is enabled. Log only

alarms will be counted and displayed in the ALA screen, but will not

cause the EAC-2100 to dial its programmed alarm number.

The default values shown below will be adequate for most installations.

To change an alarm, type the letter of that alarm and <CR>.

To alternate between the two Critical Alarms Menu displays, type Z

<CR>.

8. Type O <CR> at the Alarms Menu to review the RSSI Alarms Menu.

B Donor DCCH Channel RSSI - Low Alarm Point is the most critical

of these alarm thresholds. This threshold should be set lower (within a

range of -85 to -95 dBm), to ensure continued operation, under the

following circumstances:

• If the booster is being operated at a minimum (-75 dBm) donor signal

level and some fading exists on the donor-to-booster path.

A and C, Donor DCCH/DTC Channel RSSI - High Alarm Points, may

be set at a level 10−15 dB higher than the normal signal levels being

received from the donor, if desired. This will allow the EAC-2100 to log

alarms in the event of IF board failures with their RSSI measuring circuits.
