What is ISDN, anyway?

ISDN cards and TA's are like modems, but 5 times faster. They require special telephone lines, which cost a little (or a lot, depending on your phone company) more than normal phone lines. For more info:

  Martin writes:
  'cFos' is a DOS FOSSIL driver / BIOS INT 14h Emulator for ISDN. It was written to run FIDO compatible software and other programs using INT 14h to access conventional modems. Its built in AT command set emulator translates AT modem commands to CAPI calls thereby providing easy access to ISDN boards which come with a CAPI driver. If you have an ISDN board with a CAPI driver, all you need to do is: load the CAPI driver, load 'cFos' and you are ready to run your existing application software.

ISDN is a temporary discussion list set up for an Ad Hoc Coalition on Low Cost ISDN tariffs. The list is open and unmoderated. The purpose of the list is to discuss proposed amendments to HR 1555 (Communications Act of 1995) which would require local exchange telephone carriers, which do not face substantial competition, to offer ISDN services at prices which are reasonable, given the cost of providing the service.

ISDN non-RFC standards information

ITU (nee CCITT) Standards
- Series I Recommendations (Lots of ISDN stuff)
- Q-Series Standards
  - Q.931 [EuroISDN low level] - Digital subscriber signalling system No 1 (DSS 1) - ISDN user-network interface layer 3 specification for basic call control
- V-Series Standards
  - V.11 [High speed TA interface] - Electrical characteristics for balanced double ...
  - V.24 [Low speed TA interface?] - List of definitions for interchange circuit...
  - V.25bis [TA Dialling] - Automatic calling and/or answering equipment on the general switched telephone network (GSTN) using the 100-series interchange circuits
  - V.35 [High speed TA Interface] - DTE-DCE interface for T1 speeds
    Obsolete. The name lives on, probably incorrectly. Ken Krechmer writes:
    V.35 has been removed from the ITU-T Recommendations for some 4-5 years. It originally identified a 48,000 bit/s group band modem and was often referenced for the interface (usually incorrectly). Now there is no "V.35" in ITU. There are a number of variations (both electrical and logical) in the market of the high speed digital interface. Users would be advised to consider TIA 530 (which has a mode of operation via cable change to support most of the possible "V.35" variations).
  - V.120 [Asynchronous Emulation] - Support by ISDN of DCE with V-series type interfaces with provision for statistical multiplexing
- X-Series Standards

The ISDN API battlefield

CAPI - the Common API for ISDN - de facto German standard
- version 2.0 (English; zipped MS-Word; 700KB) CAPI 2.0 supports more operating systems and countries than does 1.1.
- version 1.1 (English, plain ASCII), script to add form feeds, Extensions for Fax, Touchtone, V.110, Novell(German)
- CAPI Working Group directory -- replaced by CAPI Assoc. site
- CAPI Assoc. FTP Site
  (Really, it's CAPI e.V., but e.V. kinda means Association.)
- IAIK ISDN ACIVITIES --
NIST's ASI - nearly defunct American standard - used by SGI
- NIST ASI docs
ETSI's PCI aka Appli-Com - yet another complex ISDN API - no known implementations
- German & English docs
WinISDN - simple, US-only?, MS-Windows-only API.
(Not much more complicated than an ethernet driver, according to one developer.)
- current version (Microsoft Word)
- ftp directory
Intel's PII - multiprotocol plug-ins for Winsock (including raw ISDN access)
Windows Telephony Application Programming Interface (for Microsoft environments only)
TAPI An experimental European standard API for accessing ATM networks (Unfortunately named!)
