TELENET SCANNING
Telenet is the largest Packet Switching network, that I know of at this
present time, I could waste valuable buffer space explaining what packet
switching is and what its uses are ect...so for more information read
"Packet Switching (tomorrow's communications today) by Roy D. Rosner. It
is quite indepth and one of the books I cherish in my "legal" Telecomm
library.
DEFINITION of GTE TELENET : The packet switching subsidiary of General
Telephone and Electronics. It provides nationwide common user data
communications via packet switching
Information on GTE TELENET :
----------------------------
The GTE Telenet commercial packet switched network was developed as a
commercial venture of many of the same principals who developed ARPANET.
GTE Telenet first became in 1979.
OPERATION :
------------
Telenets network operation and internal protocals evolved from the ARPANET
experience , with additional cababilitys built into each of the switching nods.
The network is mostly a ciruit bases packet switching protocol, that does meet
the requirments of the CCITT X.25 protocol at the user interface. In addition,
Telenet also provides customized user interfaces to meet the need of the
individual users. It also provides emulation interfaces.
USER ACCESS :
-------------
User access to the network is through one of the three clases of telenet
central offices, such as the one in San Fran, support user access speeds up to
56k bps is a Class I. Class II offices, such as the one in Spokane,Wa provide
connection speeds up to 9600 bps. Class III offices support rates up to 1200
bps, such as the one in tucson,arizona. User access can be made to Public
Dialin ports, private dial in ports, or fixed ports dedicated full time for a
single user. Users can implement X.25 compatable software in there host
computer or they can just use the T-net provided interface processors to
provide network service. Terminal Clusters can be accessed to the network very
effciently by use of Telenet access controllers placed at the customers
residece or business,ect..
Telenet Dialups
---------------
To find the local Telenet dialup for your area just call WATS to 800-TEL-ENET
and ask them for it but remember to watch out "Every thing you do on telenet is
saved on Mega tape for up to 5 years, and they have installed number
identification since December 1987,
WATS TELENET DIALUPS....
(800) 424-9494 300/1200 BPS
(800) 238-0631 2400 & MPE
These wats will change in aug. 88 so if you would like the new ones leave my
E-Mail on Lunitics Labs (415) 278-7421
What to do one you have your POTS dialup:
-----------------------------------------
Remember to do any scanning on telenet you need a POTS dialup not a WATS, the
WATS dialup is mainly used for Telemail or GTE MAIL., or SPRINT HP's Call your
local dial up and you should see something that says TELENET 617 18m, or
whatevr...just hit a few times. and you should see something that looks
like this.
@
at the "@" prompt type in NPA XXX..for now just use your area code...
like this....( this is a Network User Address or NUA)
@ 415 333
it will then either connect you, or say "Collect Connection Refused",
because you have not used an NUI, more on NUI's later...
you will see one of the following :
1) call connected ....
2) Remote Procedure Error 11 b6
3) Remote Procedure Error 11 e2
4) Not Reachable 05 e6
5) not reachable 05 db
6) Not operating ....
7) illegal address 03 80
8) Busy 01 00 .....
9) enhanced network services unavalible at this time please try again 05 d8
10) illegal address 03 ba
11) rejecting 00 7e
12) illegal address 03 42
13) remote procedure error 11 31
14) Refused collect connection 19 00 .....
