Modem was intended as a substitute for "dying" Arcor speed modem 200. The Allnet modem connected and immediately (!) Was doing well again, and Internet telephony. Supplied power cord have passed. Better and convenience at its best !! Who wants to replace its Arcor modem will be well served here !! Addendum: DSL port on the modem Allnet has different socket than the Arcor modem. Was a short moment of shock for me: but there is a cable that fits perfectly as a link to the Arcor starter!
