NetLink Wireless Telephones
– Employees can carry Wireless Telephones to make
and receive calls as they move throughout the building. The Wireless Telephones are
to be used on-premises; they are not cellular or satellite phones. They are connected
to the facility's existing telephone system and to the NetLink Telephony Gateway.
Just like wired telephones, they 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.)
Wireless Telephones use spread spectrum radio technology, which comes in two
variations, frequency hopping (FH) and direct sequence (DS). Although the outward
appearance and operation of the two Wireless Telephones is identical for both
varieties, some installations may find better radio performance with one or the other,
depending on local conditions affecting radio wave propagation or interference. The
spread spectrum technique used by the Wireless Telephones must match that used by
the access points. Discuss the choice of spread spectrum technology with your access
point provider. NetLink Wireless Telephones can operate at up to 11 Mb/s in a DSSS
(Direct Sequence Spread Spectrum) system.

NetLink Telephony Gateway
– serves as the connecting point, or gateway, between
the LAN and the existing telephone system. One or more NetLink Telephony
Gateways are typically installed in the telephone equipment room. Each NetLink
Telephony Gateway supports up to 16 telephone lines and Wireless Telephones. Up
to 40 NetLink Telephony Gateways can be connected to the LAN to support
additional telephone lines. If five or more NetLink Telephony Gateways are
connected to the LAN, a NetLink SVP Server must be installed to handle the
increased call volume.
SpectraLink offers digital NetLink Telephony Gateways that work with the digital
ports on most common brands of telephone systems (PBX or key systems). We also
offer an analog NetLink Telephony Gateway that works with telephone systems (CO,
PBX, or Key Systems) with analog (loop start) ports.

Access Points
– supplied by third party vendors, access points provide the
connection between the wired Ethernet LAN and the wireless (802.11) LAN. Access
points (AP) must be positioned in all areas where Wireless Telephones will be used.
The number and placement of access points will affect the coverage area and capacity
of the wireless system. Typically, the requirements for use of NetLink Wireless
Telephones are similar to that of wireless data devices. Contact SpectraLink, or a
certified SpectraLink distributor, for specific information about your facility’s needs.
The NetLink system must connect to access points that utilize SpectraLink Voice
Protocol (SVP). Contact SpectraLink, or a certified SpectraLink distributor, to verify
that your AP and its software version are supported.
