Placing Multilink PPP Calls

Before you place a call, ensure that the Multilink PPP box on the 3C882 ISDN modem Configuration dialog box is checked. Also, the destination you are calling must also support Multilink PPP. For example, if you are trying to dial into the Internet, your Internet service provider must also support Multilink PPP in order to successfully place a Multilink PPP call.

Although this is not generally the case, your Internet Service Provider may require an Endpoint Identifier Class and an Endpoint Identifier. The Endpoint Identifier Class is configured using S register 82. The Endpoint Identifier is configured using S register 83. Refer to Appendix B for acceptable values.
