We used to have two ISDN lines into the lab but dropped them a few years ago due to their prohibitively high operating costs.Īlong with an integral ADSL2/2+ modem, the router provides the standard quad of Fast Ethernet LAN ports. We’re not convinced this is a big selling point as ISDN in the UK is in decline with some businesses using it mainly as a backup connection to their broadband link.

Another feature that makes this router stand out is support for ISDN as well as its S0 bus, which allows ISDN telephones and PBXs to be connected via a dedicated port. It also supports 125Mbps g++ which the company reckons is around 35 per cent faster that 11g speeds.Īs with its predecessor, the 7170 functions as a two-port PBX enabling phone calls to be made over the Internet and landlines as well. AVM has never been tempted to enter the draft 802.11n fray so you’ll find the router incorporates a standard 802.11b/g access point.

We rather liked its Fon WLAN 7140 for its sophisticated SIP functions and the latest 7170 brings even more features to the table.ĪVM offers two new models and your choice will be determined primarily on whether you want wireless services as well as only the 7170 is endowed with these – the 5124 is aimed at basic Internet and VoIP services only. AVM has traditionally focussed on delivering extensive VoIP services with its unforgettably named Fritz!Box routers.
