Avaya IP Office 3600 Series Installation Manual page 8

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
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.
