Anleitung Zusammenfassung


The compact and el- egant design of VM1188T allows users to make VoIP calls at work, home, and on campus with POTS like voice quality The modulation of VM1188T is based on the WiFi standard; it is compatible with almost all standard 802.11b/g access points. With the VM1188T, users can access to both PSTN and SIP networks as long as there is a trunking gateway available at the CO side. With the easy startup, users don’t have to remember the SSID or security key of each AP, the VM1188T stores these configurations and will connect to the access points automatically when boot up. Paired up with the cradle access point CAP2316A, users can enjoy the benefit of interference free wireless environment through the implementation of MSSID. With Accton’s VM1188T, users can enjoy the benefit of cost reduction with SIP, mobility with 802.11b/g WLAN, and hassle free installation with easy startup. The VM1188T is pact with user friendly features all in a single device. The VM1188T VoWiFi phone is compliant with IEEE 802.11b/g wireless standard, and sup- ports SIP for voice applications. VM1188T allows users to make or receive VoIP phone calls as long as users are in the coverage of wireless LAN. Users can enjoy the convenience of wire- less mobility and the cost savings of VoIP without powering on the PC. Features and Benefits Advanced Security Open Standard SIP v2 Support The call control protocol of the VM1188T is based on SIP v2 (Session Initiation Protocol version 2, RFC 3261) open standard, which is interoperable with major SIP-based call serv- ers, IP-PBXs, and other standard SIP-based client devices. The VM1188T will support WiFi Protected Access (WPA) and WPA2 with pre-shared keys (PSK). WPA supports TKIP while WPA2, supports AES encryption. WPA, and WPA2 address some of the security risks inherent in the legacy Wired Equivalent Privacy (WEP) protocol. Specifically, they provide stronger authentication and encryption than WEP. Enhanced Power Saving Design for Extended Standby and Talk Time With an improved power-saving design, the VM1188T can be used for a relatively long pe- riod of standby and talk time. With an extended life for each recharge cycle, the VM1188T is available where and when you need it. Roaming between APs The VM1188T supports 802.11f Inter Access Point Protocol (IAPP) to provide STAs with constant IP-connectivity when users moving around in the environment of multi access points. The VM1188T uses L2 Mobility to allow Stations to roam between APs inside their Home IP Network. Industry-standard 802.11b/g Network Compatibility The VM1188T allows customers to achieve cost-saving efficiency with convergence of voice and data over a single wireless network. With the support of 802.11g and backward compatible with 802.11b, the VM1188T will not slow down network throughput while running in a pure 802.11g wireless environment Exceptional Voice Quality The QoS function of VM1188T will maintain exceptional quality in a shared wireless voice and data network by prioritizing voice to have higher priority then data packets. The WMM(802.11e) provides optimum Quality of Service (QoS) by delivering real time applica- tion packet with higher priority. The WMM will recognize the Types of Service (TOS) field of the IP frame to assign the priority for the IP frames. The QoS function of VM1188T will also look up 802.1p tag when VLAN is ena- bled. By providing preference to voice packets over data packets on the wireless LAN, this prioritization of packets helps increase the probability that all voice packets will be trans- mitted efficiently.
