This will reduce power requirements and ex— ing a radio‘s parameters can be performed at the tend battery life, further reducing trips to remote sites. remote site or "Over—the—Air" via the remote‘s master station. Available Alligator Interface modules allow connection by telephone line or microwave link to the The Model 1888‘s "Over—the—Air" adjustment capability master station. It is possible to monitor and reconfigure greatly reduces trips to remote radio sites, saving you an entire network of Alligator radios from your office or time and money. any location with land line or cellular telephone services. Changing frequencies, alarm limits, power levels, deviation, sleep timers, and operating para— meters can all be performed without dispatching a Event Counters technician to the remote site. The Model 1888 radio also has a set of event coun— ters. These counters keep track of several different Alarm Limits events such as PTT keying, receiver squelch, and transmit time out. Tracking these variables helps pin Also available on the Model 1888 is a group of user point the source of nagging data errors. programmable alarm limits. These limits monitor the performance of several diagnostic parameters and generate an alarm condition should any parameter Radio Upgrade by Telephone exceed its limits. With the RTU monitoring the alarm status output of the radio, alarm conditions can be Any optional features or future enhancements can be quickly noted and corrective action taken to prevent upgraded without sending the remote radio back to the further degradation of radio performance. With early factory. An Alligator technician can dial—up and access detection and Alligator‘s "Over—the—Air" capabilities, the radio through its associated master station and most corrections can be performed without visiting the upload the selected features directly to the remote. remote site. Simple Loopback Test Remote Frequency Fine Tune Every Model 1888 radio is equipped with loopback test The Model 1888 is also available with a frequency fine capabilities. Performing a loopback test requires a tune feature. With this feature installed, the user can handset equipped with a touch—tone pad connected to fine tune the remote‘s frequency offset to account for the master station orderwire. Use the handset to key in the unavoidable long term crystal aging. Like all other the loopback code and the address of the remote of features, frequency offset tuning can be performed interest. The remote will then respond with either a "Over—the—Air". Yearly visits to all remote sites for steady three second tone or three short beeps. A frequency calibrations are a thing of the past. steady tone indicates all is well. Three short beeps Alligator Model 1800
