Dialcodes(4)


NAME

  Dialcodes - Contains the initial digits of telephone numbers used to
  establish remote connections over a telephone line


SYNOPSIS

  /usr/lib/uucp/Dialcodes


DESCRIPTION

  The /usr/lib/uucp/Dialcodes file contains the initial digits of telephone
  numbers used by the uucp program to establish remote connections over a
  telephone line. The Dialcodes file simplifies entries in the
  /usr/lib/uucp/Systems file for sites where a number of device telephone
  numbers have the same prefix. If users at your site communicate regularly
  by way of telephone lines and modems to multiple systems all located at the
  same remote site, or to multiple systems located at different remote sites,
  use dial-code abbreviations in the /usr/lib/uucp/Systems file rather than
  entering the complete telephone number of each remote modem in that file.

  The Dialcodes file contains dial-code abbreviations and partial telephone
  numbers that complete the telephone entries in the /usr/lib/uucp/Systems
  file. Entries in the Dialcodes file contain an alphabetic prefix attached
  to a partial telephone number that may include the following information,
  in the order listed:

   1.  Codes for an outside line.

   2.  Long-distance access codes (1 and the area code, if the modem is out
       of the local area).

   3.  The 3-digit exchange number.  The relevant alphabetic prefix
       (representing the partial telephone number), together with the
       remaining four digits of that number, is then entered in the Phone
       field in the /usr/lib/uucp/Systems file.

  Following is the form of an entry in a Dialcodes file:

       DialCodeAbbreviation  DialingSequence

  The DialCodeAbbreviation part of the entry is an alphabetic prefix
  containing up to eight letters, established when setting up the dial-code
  listing.

  The DialingSequence comprises all the digits in the number that precede the
  actual 4-digit telephone number.

  Note that if your site uses only a relatively small number of telephone
  connections to remote systems, include the complete telephone numbers of
  the remote modems in the /usr/lib/uucp/Systems file rather than using
  dial-code abbreviations.

  Enter each prefix only once in the Dialcodes file.  When you have set up a
  dial-code abbreviation, use that prefix in all relevant entries in the
  /usr/lib/uucp/Systems file.

  Only someone with superuser authority can edit the Dialcodes file, which is
  owned by the uucp program login ID.


EXAMPLES

  The Dialcodes file on system venus contains the following dial-code prefix
  for use with a number in the /usr/lib/uucp/Systems file:

       local  9=555

  The Systems file on system venus contains the following entry for system
  zeus, including a telephone number and a dial-code prefix:

       zeus Any ACU 1200 local1212 in:--in: nuucp word: thunder

  When the uucp program on system venus dials system zeus, it uses the
  expanded telephone number =5551212.
