Configuring Multilink PPP

Multilink PPP is a protocol which provides a method for combining multiple PPP connections. Multilink PPP combines the two ISDN B channels, creating a virtual single digital connection of up to 128 Kbps. Note that the destination you are dialing must also support Multilink PPP, or the dual-channel link will not occur and you will get a single

B channel connection.

By default, Multilink PPP is enabled. To enable or disable Multilink PPP, do the following:

1Click inside the Multilink check box in the PPP area to clear it (disable) or check it (enable).

2Click the Update Configuration button to download the change to your 3C882 ISDN modem’s S register.

Additional configuration may be needed for Multilink PPP. For details refer to S registers 82 and 83 in Appendix B.
