Can I use any modem with my DSLExtreme DSL service?
No. For ATM circuits you must have an ADSL modem that supports rfc1483 bridge mode. SDSL modems are not compatible. Frame relay circuits will only work with Fujitsu DSL modems. Regular 56k dial-up modems will not work as a DSL modem. If you want to use a modem from another source, please check with us first to determine compatibility.
