4.01) Where can I find what all of these acronyms mean? An archive of telecommunication related files are maintained on lcs.mit.edu in the telecom-archives sub directory. There is a glossary of general telecom acronyms, as well as an ISDN specific list. jms@romana.Tymnet.COM (Joe Smith) asks: PMW1@psuvm.psu.edu (Peter M. Weiss) ------------------------------ 4.02) What are the relevant standards? There are numerous ITU-T (formerly CCITT) standards on ISDN.

Information about National ISDN is now available by anonymous FTP (File Transfer Protocol) over the Internet at host "info.bellcore.com". FTP allows the retrieval of formatted documents and software. The rest of this document assumes that you have access to a machine connected to the Internet that supports FTP, and that you have a system that can print both ASCII formatted documents and PostScript formatted documents. The files are available in PostScript through anonymous FTP from "info.bellcore.com" in the /pub/ISDN sub directory. I M P O R T A N T: Many of the files are large, it is essential that you first get the README (the upper case is important) file for detailed information on retrieving various files associated with documents. The following text describes a typical anonymous FTP session: system: ftp info.bellcore.com Connected to info.bellcore.com. 220 info FTP server (SunOS 4.1) ready. Name: anonymous 331 Guest login ok, send ident as password. Password: 230 Guest login ok, access restrictions apply. ftp> cd /pub/ISDN 250 CWD command successful. ftp> mget README mget README? yes 200 PORT command successful. 150 ASCII data connection for README (8758 bytes). 226 ASCII Transfer complete. local: README remote: README 8943 bytes received in 0.19 seconds (46 Kbytes/s) ftp> quit 221 Goodbye. represents pressing the "enter" or "return" key on your computer keyboard. The README file is in ASCII format and may be read with most word processors. The other files in the directory are in PostScript format and may be downloaded as needed by using the "mget" command while in the FTP. You should determine your local procedure for printing PostScript documents. For example, on many UNIX systems, PostScript files may be printed on a PostScript printer by using the "lpr" command. A typical Post Script print command may look like: lpr -P -h -v where: represents printer name accessable to your system, and represents a PostScript file. notes: '-h' corresponds to the option of suppressing the printing of burst page while '-v' corresponds to the option of printing raster image, i.e., PostScript. Please note that the printer must support PostScript imaging model in order to print these files. Some systems are configured to detect PostScript formatted files automatically, so a command to print the documents on that kind of system is: lpr -P If you have problems or you'd like to comment on the information stored at this site or wish to make recommendations for future enhancements, you can send email to: isdn@cc.bellcore.com Or, call the Bellcore's National ISDN Hotline: 1-800-992-ISDN A recent visit to the system revealed the following directories: CATALOG: NIUF (National ISDN User's Forum) catalog: "A Catalog of National ISDN Solutions for Selected NIUF Applications, Second Edition."
