1. Introduction and background.
-------------------------------
To answer the near-term need for products implementing dial-up
functionality for X.400, both ISOCOR and maXware have recently
introduced off-the-shelf products supporting a dial-up mode.
In the case of ISOCOR's X.400 Lite product, a DOS-based X.400
server can dial into centralized communications hubs and/or
remote sites with a similar configuration.  Travelling users
on notebook computers can dial into ISOCOR's X.400 servers as
well using async as well.  Also supporting X.400 dial-up are
Norwegian Telecom/maXware's products which include Remote User
Agents (RUAs) for dial-up 1988 X.400 Message Store access via
PADs.


2. Charter
----------
The following charter was presented:

APS ALLIANCE CHARTER

- The APS Alliance aims to facilitate the use of X.400-based
  messaging by using dial-up connections to dramatically
  reduce costs and complexity.

- The APS Alliance will:

  - Develop and promote a global standard for OSI
    communication over standard dial-up telephone networks
    (PSTNs), with a particular focus on X.400/X.500.  Both
    client-server and server-server communications to be
    covered by the same stack.

  - Pursue an aggressive development schedule with the near
    term goal of delivering a specification proposal to the
    Internet community and CCITT for formalization.

  - Involve software developers, systems vendors and service
    providers to ensure universal acceptance.


3. Organization
---------------
The following organization was presented:

                 -----------------------

interim editor for the user requirement phase.

An external consultant will be hired to be Editor for the
technical specification.

Members, commitments payment:
Any company can join the Alliance as a member company. The
members will have to pay a membership fee which will be used
to pay an external consultant to be the editor for the
technical specifications. David Knight will distribute a
formal charter and a membership application form to all
interested parties.

The deadline for charter membership commitments is November
20th.

Voting rules:
-------------

   Mar 20                                      Final spec

As you can see from the proposed plan, the time schedule is
very aggressive, and will only hold if all involved parties
are cooperating fully.

The first important deadlines are:
   Nov 13  Deadline for comments to the preliminary user
           requirements.
   Nov 20  Deadline for written commitments from the members.
           (Members joining after this date will not be able
           to vote on the user requirements).
   Dec 1   Deadline for votes on the User Requirements.
   Dec 3-4 Workgroup meeting in London


The procedure will be:
Basic Spec.
        Deliver Spec.
                Build Prototype
                        Start Pilot - Deliver Spec to Standards
                              committee.

5. User Requirements
--------------------
The first draft of a user requirement document was presented.
The second draft, updated with some comments from the audience
is enclosed with this message.

6. Discussion
-------------
The following major limitations to the user requirements where
proposed and endorsed by the audience:

 - The aim is to connect an application to a service (as
   opposed to connecting a computer to a network).
   Connection oriented Transport service, possibly including
   support for multiplexing (TP0 or TP2).

 - It was a general agreement that wireless communication is
   important, but that this consortium does not aim to solve
   problems related to wireless communication.

 - Several persons stated their concern that if this
   consortium should tackle security issues, the proposed time
   schedule will not hold.

(A second phase of specification may be initiated when the
work from the first phase is submitted to the standards bodies
to work on security and wireless).


Comments from induvidual particippants:
- Security is best handled at the application level
  (encryption etc.. ). However, security in the form of
  authentication may be part of this project.
- Security will be needed if the protocol supports multiple
  sessions.
- PPP might be a model to use (Point-to-Point-Protocol for
  TCP/IP)
- Is it possible to handle both TCP/IP and OSI Apps?
- Managability
- Dial-in/Dial-out
- Dial back
- P7 has a high overhead.  We might be better served to look
  at a short stack P7.
  However if we stray from the network layer solution we do
  not have an entry into CCITT.



There was a wish to establish a set of user profiles as a
background for the user requirement work:

USER PROFILES

 - Mobile User to corporate X.400 MS or public MS
                - On telephone line
                - Wireless

 - Office to Office
                - Client to Server
                - Server to Server

 - Smaller office to corporate hub or public MS



7. Where do we go from here
---------------------------
- the formal charter + registration form + partisipant fee
  information will be sent to all interested parties.
- the deadlines mentioned above
  (please discuss this with your end-users)


--------------------------------------------------------------
APS Alliance
Suggested User Requirements


1. Provide means for running OSI-applications in general and
X.400 in particular over dial-up thelephone networks.

2. The solution should be suitable for all industry standard
operating systems and hardware platforms.

3. Support for multiple assosciations over the same physical
connection (e.g. P7 and DAP)

4. Efficiency and simplicity (minimal overhead, high
throughput, small amount of resource consumption, easy to
implement, small memory demands).

5. Require minimal changes to existing implementations

6. provide support for both point-to-point connections and
access PAD and PSDN network.

7. Must support use of any (automatic) modem and any PAD
service.
This means that the protocol cannot rely upon error
correctiondone by the modem. The protocol must support use of
both 7bit and 8bit PAD. The length of the PDU to be sent over
the PAD must be configurable.

8. Provide reliable transfer service by including functions
for error detection and error recovery.

Added requirements since 1st version was distributed:
-----------------------------------------------------

18. Allow for compression

19. Include placeholders for security features (which may be
added as a "phase two".

20. The low-layer protocol should be based on some existing
standard or implementation. (many candidates exist, ppp, z-
modem, X.32bis etc).

Technical user requirements
---------------------------

9. Provide a bit-transparent transfer service

10. Support use of flow control

11. Point-to-point solution should be symmetric (both parties
may take initiative to connect)

12. No restrictions on use of particular transport service.
(preferably provide an X.213 interface, and run higher layer
protocols transparently.

13. Provide the ability to identify calling party (calling
NSAP)

15. Configuration parameters should provide the ability to
optimize throughput and reduce costs, dependent of the
communication line.
Error correction compression on modem should be used if the
modems provide it.

16. Negotiation during connection establishment of possible
options.
(PDU size, windows size etc)

17. Optionally provide the ability to recover from telephone
line break when using application contexts without RTSE (e.g.
by means of TP class 4).

18. Quality of service
    - Residual error rate should be comparable to X.25
