2 Pre-Installation
Before installing Ascom i62 handsets in a VoWiFi system, make sure that all equipment is
available. It is recommended to set up chargers and charge the handset batteries before
installation, and to have a number plan available for the handsets. Also be sure that the IP
addressing plan is set up to support the amount of handsets to be deployed.
We assume that the VoWiFi system is installed including some or all of the following
components (depending on system configuration):
• VoIP Gateway. This is the gateway for ISDN primary rate interfaces (PRI) in the Ascom
VoWiFi. It serves as a link between traditional telephony and VoWiFi telephony.
• DHCP Server. A DHCP server allows devices to request and obtain an IP address from a
server which has a list of addresses available for assignment. If the WLAN does not have
access to a DHCP server, a list of static IP addresses is necessary.
• Portable Device Manager (PDM) (Windows version). The WinPDM is used for
administration and programming of the i62 VoWiFi handsets. All settings and updates
are in this case done via the DP1 Desktop Programmer cradle connected over USB.
• IMS2. The IMS2 handles all communication between the WLAN and its built-in Device
Manager. Before installing the handset make sure the IMS2 IP address is available.
For effective administration of a VoWiFi system with several handsets, it is required to have
both a WinPDM and a Device Manager included in the IMS2. In this case, the WinPDM is only
used to allow the handset to access the WLAN system. All other settings and updates are
done with the Device Manager in the IMS2.
