• Access Points
Supplied by Avaya or third party vendors, access points provide the connection between the
wired Ethernet LAN and the wireless LAN. The access points used must support the SVP QoS
applied to 3600 Series voice traffic by the AVPP. For a complete list of access points supported,
go to: www.spectralink.com/consumer/resources/wifi_compatibility.jsp.
• Access points must be positioned in all areas where wireless phones will be used. The
number and placement of access points will affect the coverage area and capacity of the
wireless system. Typically, the requirements are similar to those of wireless data devices.
• IP Office Control Unit
Use of 3600 Series phones via an AVPP is supported on all types of IP Office control unit. The IP
Office is the telephony switch and each 3600 Series phone must be configured as a user and an
extension on the IP Office.
• The IP Office control unit must be fitted with voice compression channels. The number of
available channels at any time may restrict the number of calls between 3600 Series
phones and other non-IP phones and lines. The method by which voice compression
channels are fitted to an IP Office control unit will depend on the control unit type. Refer to
the IP Office Installation manual for details. which may have to be fitted as an additional
component.
• Note that whilst the Small Office Edition control unit is able to support a built-in wireless
access point, that access point does not provide support the SVP protocol required for
Quality of Service (QoS).
• Ethernet Switch
Interconnects the multiple network devices, including the AVPP, IP Office and the access points.
For small site the IP Office control unit may act as the switch, however for larger sites a
dedicated switch is recommended.
• Although a single Ethernet switch network is recommended, the wireless phones and the
AVPP can operate in larger, more complex networks, including networks with multiple
Ethernet switches, routers, VLANs and/or multiple subnets. However, in such networks, it
is possible for the Quality of Service (QoS) features of the AVPP to be compromised and
voice quality may suffer. Any network that consists of more than a single Ethernet switch
should be thoroughly tested to ensure any quality issues are detected.
•
The 3600 series wireless phones cannot "roam" from one subnet to another. If routers
and multiple subnets are in use, the wireless phones must only use access points
attached to a single subnet, or be powered off and back on to switch to a different subnet.
• IP multicast addresses are used by the 3626 and 3645 wireless phones. This requires
that multicasting be enabled on the subnet used for the wireless phones and AVPP
servers. Routers are typically configured with filters to prevent multicast traffic from
flowing outside of specific domains. The wireless LAN can be placed on a separate VLAN
or subnet to reduce the effects of broadcast and multicast traffic from devices in other
network segments.
• Administrative Computer
A computer is required for setup and maintenance of the AVPP. This computer can be
temporarily connected directly to the component or to the network, a dedicated computer is not
required. Some installations use a laptop to configure and maintain system components.
• TFTP Server
A TFTP server is required in the system to distribute software to the wireless phones and the
AVPP. The AVPP units do not support the IP Office internal TFTP server. To download Avaya's
free TFTP server, go to www.avaya.com/support.
•
DHCP Server (Optional)
The AVPP requires a static IP address. However the 3600 Series phones can use either static
addresses or they can use a DHCP server to obtain their addresses.
