PPP over ISDN

Status of this Memo

This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited.

Abstract

The Point-to-Point Protocol (PPP) [1] provides a standard method for transporting multi-protocol datagrams over point-to-point links. This document describes the use of PPP over Integrated Services Digital Network (ISDN) switched circuits.

This document is the product of the Point-to-Point Protocol Working Group of the Internet Engineering Task Force (IETF). Comments should be submitted to the ietf-ppp@merit.edu mailing list.

Applicability

This specification is intended for those implementations which desire to use the PPP encapsulation over ISDN point-to-point links. PPP is not designed for multi-point or multi-access environments.

"It is clear that there is never likely to be a single, monolithic, worldwide ISDN." [3] The goal of this document is to describe a few common implementations, chosen from the current wide variety of alternatives, in an effort to promote interoperability.

RFC 1618 PPP over ISDN May 1994

1. Introduction

PPP was designed as a standard method of communicating over point- to-point links. Initial deployment has been over short local lines, leased lines, and plain-old-telephone-service (POTS) using modems. As new packet services and higher speed lines are introduced, PPP is easily deployed in these environments as well.

This specification is primarily concerned with the use of the PPP encapsulation over ISDN links. Since the ISDN B-channel is by definition a point-to-point circuit, PPP is well suited to use over these links.

The ISDN Primary Rate Interface (PRI) may support many concurrent B- channel links. The PPP LCP and NCP mechanisms are particularly useful in this situation in reducing or eliminating hand configuration, and facilitating ease of communication between diverse implementations.

The ISDN D-channel can also be used for sending...
