Installation Guide
The following table shows maximum users per AP based on the AP’s ability to handle simultaneous calls:
User Calling Intensity Light Moderate Heavy
Erlangs per User 0.10 0.15 0.20
Max Active Calls per AP
Users Supported per AP
(1% Blocking Probability)
1 1 1 1

3 4 3 3
4 8 6 4
5 13 9 7
6 19 13 10

Users Supported per Access Point
Areas where heavier wireless telephone usage is expected, such as cafeterias and auditoriums, can
obtain higher call capacity and handle more users by installing additional APs. For most enterprise
applications however, the table above should be sufficient in demonstrating the number of wireless
handsets supported within each AP’s coverage area.
3.0 Network Infrastructure Considerations
3.1 Physical Connections
Avaya wireless telephone infrastructure components must connect to a facility’s LAN using Ethernet
switches rather than Ethernet hubs in order to provide adequate bandwidth and limit traffic collisions and
bottlenecks.
Ethernet switches should be configured to negotiate the connection requirements automatically. AVPPs
can be set to automatically negotiate the Ethernet connection however 100Base-T, full-duplex
transmission is required to support the maximum simultaneous voice calls and optimal system
performance.
Network wiring is an important component of any Ethernet-based system and is subject to local and
state building code specifications. Cat 5 or better, 4-pair 10/100 Base-T Ethernet cabling should be used
for Avaya wireless telephone infrastructure equipment.
3.2 Assigning IP Addresses
Avaya wireless telephones operate as LAN client devices and therefore require IP addresses to operate
in the network. IP addresses can be assigned statically through the configuration menus on the handsets
