Davicom MAC - Monitoring, Alarm and Control for your remote sites
The Davicom MAC is designed to meet the requirements of the broadcasting and wireless telecommunications industries. These best-in-class, stand-alone monitoring and control units interface easily with virtually any type of remote site equipment and sensors, which ensures maximum flexibility and expandability. Reliable and comprehensive remote monitoring and control technology is essential for stations with remote transmitter sites. Although having a main street studio and a mountaintop transmitter can help improve both the coverage and public profile of a station, these benefits come at a price. When a problem occurs at the transmitter site, personnel must often travel there without knowing the nature of the problem nor for example, which spare parts to bring. A comprehensive remote monitoring system can tell them exactly what has happened and save valuable time.

MAC units have been designed and tested to withstand harsh RF environments. Immediate access to real-time site information, like transmitter status, antenna VSWR, audio/video levels and presence, mains and auxiliary power levels, temperature, tower lighting, fire alarm and building security status can be just a mouse click away.
In order to ensure transmission sites are continuously up-and-running, Davicom MAC systems provide automation with decision-making features and commands that go well beyond conventional telemetry systems. They can automatically perform AM antenna day/night pattern changes, program chain switching, transmitter changes, generator exercising, battery testing, etc.
|
Upon an RF failure, they can place the standby transmitter on-air to restore the signal, and alert on-call personnel. Engineering staff can then diagnose the problem from the event history log and, using remote measurements, decide on the appropriate course of action.
Multilevel alarms can be sent by the MAC to the Network Operations Centre (NOC) and other resources by e-mail, phone (voice or SMS), pager, SNMP traps, fax, modem, or to the MacNet multi-site alarm management software. The MAC's voice response system can also talk to personnel over the phone or voice pager. Multiple alarm-call lists allow the MAC to contact different groups depending on the event, or the day and time. Individual signal and status conditions can be qualified by time delays and hysteresis to prevent annoyance alarms.
MAC units can be interrogated by PC using the MacComm software, with a Web browser or SNMP manager, or by telephone to check signals and status, monitor live audio feeds and execute commands. Blackberry®, iPhone® and other smart phones and devices can also be used to monitor and control a site over the mobile Internet and from WiFi hotspots. The MAC's reach-through serial ports can be used to access and control other on-site ancillary equipment. The MAC can even ping site equipment through its local IP port and monitor for dial tone on the telephone line.
MAC units are FCC, Industry Canada and CE certified. They are also
RoHS/WEEE compliant. The management system governing the manufacture of this product is ISO9001:2000 certified.
