SpectraLink Corporation Installation and Operation
Link WTS – Link 150 M3 MCU
SpectraLink offers an analog MCU that works with telephone systems (CO, PBX or
Key Systems) with analog (loop start) ports. We also offer digital MCUs that work
with the most common brands of telephone systems’ (PBX or key systems) digital
ports.
Base Stations
Act as a radio transceiver to provide the communications signal between the handset
and the MCU. Base Stations are slightly larger than a smoke detector and are
typically mounted on the ceiling, in strategic locations throughout the facility. A
single Base Station can provide radio coverage for an area of 5,000 to 50,000 square
feet depending on building obstructions. Base Stations may be located up to 2,200
cable feet from the MCU.
When a handset user makes or receives a call, the handset and Base Station establish
a digital radio communication link. As the user moves around the coverage area, calls
are “handed off” to the Base Station that is able to provide the best radio signal
(typically the closest Base Station). These handoffs involve the handset establishing a
communication link with another Base Station and dropping the previous link.
Link Wireless Telephones
Communicate with the Base Station using digital spread spectrum transmission at
902-928 MHz. Employees can carry handsets to keep in contact as they move
throughout the building. The handsets use on-premises wireless technology; they are
not cellular or satellite phones. They are connected to the facility’s existing telephone
system and, just like wired telephones, can receive calls directly, receive transferred
calls, transfer calls to other extensions, and make outside and long distance calls
(subject to the restrictions applied in your facility.)
