PRODUCT OVERVIEW
The ascom VoWiFi system provides a reliable Voice Over IP communication solution that combines the
open standard for wireless radio networks and SIP telephony technologies. Utilizing the IEEE 802.11n
standard for wireless LAN (WLAN) communications, the ascom VoWiFi system provides the benefits of
increased speed, improved reliability and extended range of wireless transmissions.
The ascom VoWiFi system allows 2-way voice communications with residents via the Advent XT2 warden
call system and between staff, both internally and externally if required.
When the Advent XT2 is operating in onsite mode all alarm calls are reported via the VoWiFi system.
When the phone rings the caller will be identified on the display (provided the phone book memory is
programmed), when answered a voice message will announce the call type and channel ID before a speech
link is opened.
The ascom VoWiFi system comprises of 2 elements;
1.
a bundled package including a Matrix IP-
PBX, 2 x i62 VoWiFi handsets c/w chargers and PSU’s
2.
a maximum of 8 x Draytek Vigor AP 903 Mesh Access Points
The Matrix IP-PBX is preconfigured so both CO analogue trunks ring all SLT and IP extensions, it also has its
DHCP server enabled. Both ascom i62 handsets have their WiFi settings and SIP credentials preconfigured
as extensions 151 and 152. A maximum of 5 IP extensions (151 to 155 are possible). The Matrix IP-PBX
allows the VoWiFi handsets to integrate with the Advent XT2 warden call system, it also allows access to an
outside line to make/receive external telephone calls and VoWiFi handset-handset calling.
One Mesh Access Point (known as the Mesh Root) is always hardwired to the Matrix IP-PBX Ethernet port
via a standard UTP Cat5e patch lead, max length 100 metres. Up to a maximum of 7 more Mesh Access
Points (known as Mesh Nodes) can be deployed wirelessly around the building to achieve site-wide WiFi
coverage. Each Mesh Access Point requires connection to a local mains supply using the plug-top mains
adapter supplied.
If it’s not possible to power the Mesh Access Points from
a local mains supply then they
can be powered from an auxiliary 12V DC power supply, but additional site wiring will be required. The
Mesh Root supports PoE on LAN Port A1, but an additional PoE switch or PoE injector will be required.
The size/complexity of the building will determine the total number of Mesh Access Points needed to
achieve site-wide coverage. The exact positioning of the Mesh Access Points will be determined by a site
survey prior to commencing the installation. A free Draytek Wireless App is available to simplify the setup
of the mesh network;
