System Description
Ascom VoWiFi System
Handset Administration gives the possibility to list all VoWiFi Handsets and search for
VoWiFi Handsets that are registered in the system, and to see and/or change the absent
status of the VoWiFi Handset.
The Network Time Protocol (NTP) built-in server makes it possible to synchronise the time in
the whole system.
The Open Access Protocol (OAP) enables exchange of data between systems and makes
messaging from customised applications possible.
Messaging Groups is used when one message should be sent to several VoWiFi Handsets.
There are 30 groups with up to 15 users in each group and 1 group with up to 50 users. A
more advanced group handling requires an ESS module.
System 900 Interface connects directly to the system bus in System 900 and can control
the communication on the bus. If no messages are sent on the system bus, the central unit
in system 900 can be excluded.
LAN Interface is the connection to the Ethernet.
Every IMS3 supports from start (depending on the chosen licenses):
• Basic one-way messaging
• Messages with delivery receipt (automatic acknowledge)
• Messages with manual acknowledge
• Interactive messaging
• Erasure of sent messages
• Mobile data from VoWiFi Handsets
• Short Messaging Service (SMS) between VoWiFi Handsets
• Personal alarm from VoWiFi Handsets
• Central phonebook
• Alarm handling
• Fault logging
• Remote management
The following functions are achieved (license-dependent) by adding an ESS module:
• System survey
• Fault handling
• Shared phones with individual passwords
The Unite platform makes it possible to connect other Unite modules, thereby enabling
enhanced system functions, see System Description, Unite, TD 92243GB.
