The IP1200 is an IP DECT gateway that integrates DECT-compatible subscribers in the innovaphone PBX. It enables very complex DECT systems to be set up. With the multicell capability of the IP1200 base station, several devices can be installed, between which roaming and automatic handover operate. A base station supports up to 12 channels in parallel.

The innovaphone homepage (http://www.innovaphone.com) contains all current service packs, boot codes, hot fixes, firmware updates, manuals, datasheets, etc. It is also possible to request the innovaphone newsletter to stay up to date with current innovaphone news. In future, it will be possible to make complaints online via the innovaphone homepage.
It is possible to update the firmware and configuration of a large number of innovaphone devices in a distributed environment by automated means. This is done by storing the configuration and firmware information on a standard Web server, which in turn is called up the individual devices.
If the URL happens to end with a ‘/’, then a standard file name based on the product description is used. If, for example, the URL is http://1.2.3.4/ configs/ , then it is extended in the case of an IP1200 as follows: http:// 1.2.3.4/configs/update-ip1200.htm . The product name is specified in the first line in chapter “Configuration/General/Info”.

This example demonstrates how the configuration of a device is stored on a Web server; all IP1200 devices are then instructed to load/update the firware version 04-5679 in the time period 23:00 hrs to 04:59 hrs. New devices are updated after a restart and after the specified six minutes have elapsed.
Any Windows server can operate as the NTP server. Equally, there are various NTP software packages for Windows and Unix/Linux platforms. The innovaphone VoIP devices also work simultaneously as NTP servers. If several devices are being used, one device can synchronise with a time server (external if need be), and all other devices, in turn, can synchronise with this one device.

DECT radio on-site measurement. This is ultimately the only way to determine how many locations must be equipped with DECT base stations and repeaters. innovaphone AG provides a mobile DECT installation tool for carrying out this measurement without the prior installation of a DECT environment. This tool can be lent or leased, and is thus a cost-effective way to bring a professional DECT environment into operation.

For DECT radios to be able to communicate, they must be synchronised with one another. In an IP1500 system, synchronisation is obtained using the 2- wire interface of the CCFP. In an IP1200 system, it is obtained via the air, however. Therefore, an IP1200 configured as a DECT radio must be created within the coverage of another DECT radio, from which synchronisation can be obtained.
