----------- isn: How to connect across VCS/ISN boundaries. -----------
Holmdel, Crawford Hill, and Short Hills locations have mostly ISN nodes.
Other locations have primarily VCS (Datakit) nodes. In general, ISN nodes
issue the 'DIAL:' prompt, and VCS nodes issue the 'DESTINATION:' prompt.
The following examples should prove helpful in establishing connections across
the above network boundaries. The example destinations are "ih/f/iwlca" on
VCS, and "hod/houxa" on ISN.
ISN to VCS: Type '1/toll' at the 'DIAL:' prompt.
Then type 'ih/f/iwlca' at the 'DESTINATION:' prompt.
VCS to VCS: Type 'ih/f/iwlca' at the 'DESTINATION:' prompt.
VCS to ISN: Type 'ho/toll/isn' at the 'DESTINATION:' prompt.
Then type 'hod/houxa' at the 'DIAL:' prompt.
ISN to ISN: Type 'hod/houxa' at the 'DIAL:' prompt.

-------------------- netdir_doc: Netdir Tutorial. --------------------
WHAT IS NETDIR:
Netdir is an on-line database of essential system information.
Presently, its scope is limited to AT&T systems, both those
connected to the Datkit network, as well as those which are not.
As need arises, the netdir database will be updated periodically
to reflect recent changes and additions.
The information contained in each data base record consists of:
NAME: the name of the system, eg. 'ihuxa'
TYPE: system type, if available, eg. 'vax11/780'
NET ADDRESS: network address as 'area_code/exchange/host'
(note that some hosts are not on the network)
DIALUP: direct dialup numbers, if available
PATH: uucp path; replace '%s' with login name
ORG: name of organization
ADDRESS: mail address
CONTACT: contact(s), system administrator(s), etc.
BASIC USAGE:
When invoked, netdir displays the following prompt:
"PLEASE ENTER SYSTEM NAME: "
The name of the system for which information is being requested
should be entered at this point. Example: 'ihuxm'. AT this point
netdir searches the data base, and displays the retrieved record(s).
If the specified system is not found in the database, an appropriate
message is displayed.
HOW TO USE SPECIAL CHARACTERS:
In order to make the retrieval more flexible and to allow the
retrieval of groups of systems with a single query, netdir supports
a limited regular expression capability. The following special
characters are recognized:
? matches any single character
* matches any string
[] character class. examples: [ayb], [A-Zg-h], [a-z0-9].
There is presently no way to 'escape' the meaning of these special
characters. If any of the above are used, it is recommended that
the search pattern end with '*'.
Examples: ihux*, ihnp[0-7]*, ??uxa, *vax*, i?ux?, etc.
HOW TO SEARCH USING KEYS OTHER THAN SYSTEM NAME:
It is possible to search the netdir database using a key other
than the system name. To do this, enter '~key' at the netdir
prompt. You will be asked to choose a search key, and then to
enter the search pattern.
HOW TO STAT THE VERSION:
Typing '~version' at the netdir prompt will display the version
of the database, as well as the version of the program.
ONLINE COMMAND SUMMARY:
Typing '?', 'help', etc. at the netdir prompt will display a
summary of netdir usage.
DIFFERENT FROM DIRECTORY ASSISTANCE:
Netdir is *not* the same as Datakit VCS Directory Assistance,
hence it does not recognize search strings such as 'k/?',
'ih//?' etc. These are entered at the "DESTINATION: " prompt.
Please consult the Datakit VCS User's Guide for information on
how to use Directory Assistance.
REQUEST FOR COMMENTS:
Please direct comments/suggestions regarding the netdir program
to [ihnp4!]ihnp1!mth.
Please direct comments regarding the netdir database content
to [ihnp4!]ihnp1!action, or the IH Help Desk, x3333.
Thank you.

------------- dug11: [D.U.G.] On-line Trouble Reporting. -------------
An on-line trouble ticket facility for reporting datakit VCS malfunctions
is available.
To help troubleshoot problems, the NODE, MOD, and PORT information for both
ORIGINATE and DESTINATION connections is required on each trouble ticket.
This data can be obtained by entering "display" in the DK command mode
(see infor item 'dug10'.) It is also imperative that the circuit number
be reported on the trouble ticket. This number is stamped on the Datakit
VCS jack that your terminal is connected to.
It is not essential to enter the trouble ticket on your terminal. Any
working terminal can be used.
The trouble ticket entry is menu driven, and guides youn through the
entry process. At the end, your report is assigned a six-digit number.
Save this number for future inquiries.
To enter a new trouble ticket, or inquire on the status of an existing one:
ENTER: "trouble" at the "DESTINATION: " prompt.
Although the above method is preferred, troubles can also be reported to
the Help Desk, x3333.
----------------------------------------------------------------------
------------------ dug10: [D.U.G.] DK Command Mode. ------------------
This mode is used to communicate directly with the Datakit VCS controller.
The mode is identified by a "DKC" prompt on the screen.
Enter the "DKC" mode by depressing the <BREAK> key twice within one second.
This may be done at the "DESTINATION: " prompt, or when logged into a host.
The following are the DK commands. Items tagged with '*' are not currently
in service.
COMMAND ABBREVIATION EXPLANATION
------- ------------ -----------
continue c,cont Returns you to the previous network connection
* c new [tag] New call; hold current call with 'tag'
* c tag1 [tag2] Switch to 'tag1'; hold current call with 'tag2'
disconnect d,disc Drop the current network connection

To access:
ENTER: "netdir" at the destination prompt.
You will then be prompted to enter a system name. Example: "ihuxa".
You may also enter "?" for more information on netdir usage.
