- X-Tel OSI Support Services
- X-Tel provides packages for the following OSI Application Services:
-
- o X.400 - Electronic Mail (PP)
- o X.500 - Directory System (Quipu)
- o FTAM - File Transfer
- o VTP - Virtual Terminal Protocol
-
- All of the packages run on Unix on a variety of hardware platforms and
- utilise the ISODE development package. X-Tel provides a Basic Support
- Service and an Extended Support Service.
-
- A. Basic Support Services
-
- The Basic Support service includes installation, data preparation, data
- reorganisation, upgrading, and phone/network help. These terms are
- defined as follows:
-
- 1. Installation Support
- This covers supplying the tape and printed documentation for the
- required package. Software can be pre-configured for given
- hardware platforms. This support also covers help with installation -
- i.e. written notes and phone/network help with queries and advice.
-
- 2. Upgrades
- This covers supplying new releases of the software and typically
- involves a tape distribution containing update notes (printed versions
- of new manuals can be supplied at extra cost).
-
- 3. Bug Fixes
- This covers patches to the code to allow specific problems to be
- worked around between major releases. These may be distributed as
- source or binary libraries on tape or via a network connection.
-
- 4. On-Line Database
- X-Tel maintains an on-line database which provides records of
- software releases, bug fixes and documentation notes.
-
- 5. Phone/Network Help
- This service provides general help and advice about the package in
- question. Support is via a phone line, and where possible/desired, via
- X.25 to the customer premises.
-
- B. Extended Support Services
- This category of support is available as an option and is not included in the
- Basic Support Service contract.
-
- 1. Data Preparation
- This covers different things for different packages. For the Quipu
- X.500 package this involves initial assistance in setting up the
- database for the particular client directory service. For the PP X.400
- package, this would cover installation of initial routing tables, user
- tables, lists and aliases. This service is not offered for ISODE.
-
- 2. Data Reorganisation
- This covers changing the data associated with the package when
- reconfiguration is required. This might mean help with reconfiguring
- network attachments for ISODE. It would cover changing the
- database structure in Quipu to include new attributes or a different
- tree shape. In PP, it might be bringing up new links or adding new
- users.
-
- 3. On-site Assistance
- This service is only by special arrangement with a client organisation.
- A fixed time and travel charge will be levied.
-
- C. Other Services
- Other areas that X-Tel may offer individual client services in are as follows :
-
- I X.500 Directory
-
- 1. Client registration
- For X.500 to be effective, UK companies and other bodies need to
- register basic addressing information in the upper part of the directory
- tree. Such entries need to be (a) unique and (b) globally visible at all
- times for query navigation. X-Tel will offer a registration service by
- liaising with the primary registration authority on behalf of the client
- organisation.
-
- 2. Client Data registration and maintenance
- If a company wishes to register its organisation in the X.500 directory
- AND maintain data for other directory subscribers that describe its
- internal structure BUT does not wish to operate the necessary DSA,
- X-Tel offers a DSA operation support and data maintenance service.
- That is, the DSA service and the client data integrity would be
- maintained by X-Tel on behalf of the client organisation. Updates to
- the organisational data could be managed by the client or X-Tel.
