The RF102 units support Multilink PPP over dial-up connections to the Internet. Does this require that both analog modems are dialing the same ISP, with the same login credentials and have a Multilink enabled account at the ISP?

MLPPP requires both links to dial into the same ISP and the ISP must support MLPPP. Typically, the ISP will provide you one dial-in number and one username and password. All you need to do is enter the same information on both links during your setup of the RF102S.

The RF102S can be setup to dial two different ISPs or two different accounts using Standard PPP; however, the HTTP protocol is the only protocol that can utilize both links without using MLPPP.
