Placement guidelines for the WLAN IP Telephony Manager 2245 59
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.
Placement guidelines for the WLAN IP Telephony Manager 2245
To reduce the impact that jitter, delay and packet loss has on voice quality,
proper placement of the WLAN IP Telephony Manager 2245 is critical.
See Figure 10 "Maximum delay, jitter and packet loss" (page 59). The
WLAN IP Telephony Manager 2245 provides three critical functions to help
achieve exceptional voice quality over WLAN:
•
Timing
• Quality of Service (QoS)
•
Connection Admission Control
Before adding the WLAN IP Telephony Manager 2245 to the network:
•
Ensure that the APs used in the network are Voice Interoperability
for Enterprise Wireless (VIEW) certified. For more information, go to

ww.spectralink.com/consumer/partners/view_certification.jsp.
•
Ensure that the handsets are running Nortel Phase II software (97.070
or greater).
