ISDN FAQ 4/5




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.

4.04) Can I get on-line National ISDN information from Bellcore?

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 <enter>
  Connected to info.bellcore.com.
  220 info FTP server (SunOS 4.1) ready.
  Name: anonymous <enter>
  331 Guest login ok, send ident as password.
  Password: <enter your internet login -- example: student@university.edu>
  230 Guest login ok, access restrictions apply.
  ftp> cd /pub/ISDN <enter>
  250 CWD command successful.
  ftp> mget README <enter>
  mget README? yes <enter>
  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 <enter>
  221 Goodbye.

<enter> 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<printer> -h -v <filename.ps>

where:
    <printer> represents printer name accessable to your system, and 
    <filename.ps> 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<printer> <filename.ps>

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
