There are no binding standards for ISDN
For TCP/IP connections with the NDIS WAN device driver, you must use
ISDN B channel protocols and PPP variants
Many Internet providers use HDLC or the X.75 protocol on the ISDN B channel. Two protocol variants are used for PPP connections: “PPP over ISDN“, based on RFC 1618 and also known as synchronous PPP; and
Your Internet Service Provider (ISP) can tell you which protocol combinations and authentication procedures you need for ISDN access.
Incorrect protocol settings result in immediate termination of the connection or failure to establish a connection at all, with the
The computer you are dialing in to is not answering.
These settings are fixed in the Microsoft NDIS specification, and cannot be modified by the user. If you require other protocols or PPP variants, use the ISDN CAPI Port Device Driver or cFos.
Connecting computers using remote access service (RAS)
This section provides information on connecting your Windows 95 computer with another computer (Windows 95 or Windows NT) for the purpose of accessing remote files. For assistance with RAS configuration, please refer to the Windows 95 manual or
In this section, “Server” refers to the computer waiting to answer an incoming call, while “Client” refers to the computer that dials up the ISDN connection. The RAS configuration procedures for Windows 95 and Windows NT are different. Windows NT 3.51/4.0 enables you to operate RAS in server mode using the appropriate NDIS WAN CAPI Device Driver for Windows NT.
Remote access service (RAS) in Windows 95
To use RAS, you need the following components:
•An ISDN adapter with current CAPI
•The NDIS WAN CAPI Device Driver for Windows 95
•
•A network protocol (such as NetBEUI) with suitable client software, bound to the
