AN
Series:
IP Based
Communication
System
System Description (Back to top)
 |
Single exchange can connect any combination of door and master stations up to sixteen units |
|
Up to 80 exchanges can be included on a system for a total of 1280 communication devices |
|
IP Direct master station (AN-8500MS ) and vandal resistant door station (AN-8540DS), connect directly to a LAN/WAN and do not require an exchange unit |
|
Efficient method of communicating over local or wide area network using existing infrastructure |
|
Full compliment of PC Programmable functions and features including Redial, Recall, Auto-dialing, Group Call, Group Searching, Absence transfer, Call Forwarding, Call Hold, and Scan Monitor. |
|
Automatic echo canceller prevents clipping and ghosting during hands-free simultaneous conversation |
|
Stations incorporate a built-in speaker to allow paging through the units |
|
Paging through overhead speaker network using an external amplifier with total broadcast capabilities of up to 160-zones with paging and all-call paging |
|
Total system maintenance can be performed off-site using a personal computer with provided software |
|
7kHz communication frequency provides better clarity than most telephones (Network status may cause audio quality to temporarily deteriorate to 3.4 kHz) |
|
System occupies a very low amount of bandwidth |
