FRITZ!Box 7340 Service - Knowledge Base
Can the FRITZ!Box be used as a DSL modem?
The FRITZ!Box cannot be used as a DSL modem because the majority of the FRITZ!Box functions could not be used then. It would also no longer be possible to use the telephony functions and television service included in Internet packages offered with many DSL lines. Therefore, configure the FRITZ!Box for operation as a DSL router.
