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 then the majority of the FRITZ!Box functions could not be used. In addition, the telephony functions and television service included in your Internet package could no longer be used with many DSL lines. Therefore, configure the FRITZ!Box for operation as a DSL router.
