DSL Service For SLAC Users
Last Update: 25 April 2005
On This Page
DSL
DSL (Digital
Subscriber Line) provides a very fast remote Ethernet-level connection from your home to
the Internet with speeds between 192Kbps and 6.0Mbps. The speeds are dependent on
the type of service chosen and the distance between your home and the phone company
equipment that supports DSL.
The remote user will need a router or bridge unit to
connect his DSL line and workstation to the DSL service and network. There
are no usage charges, just a monthly service fee and a one time charge
that includes the cost of the DSL router and installation. The DSL
connection is "always up".
DSL Service
For SLAC Users
SLAC supports four DSL service choices from SBC
DSL and Stanford DSL.
-
SCCS is the SLAC contact for SBC DSL and Stanford DSL Service.
SCCS will submit installation requests, handle the billing, and provide
limited help when there are questions and problems. The monthly service
charges and any installation cost for your DSL service
will be charged
back to the account number you provide on the DSL Service Request Form.
-
You will be outside of the SLAC network firewall
The DSL
connection is similar to being on the public internet. To access "slaconly"
web pages or other restricted SLAC resources and to appear to be inside the
SLAC network firewall:
- Security concerns
Your workstation is wide open to hacking because of
being on the public network. There is NO absolute way to prevent
hacking if your system is up and has a DSL connection.
- Keep your system well maintained and up-to-date with the latest security
patches
and run the latest virus software. Upgrade to Windows XP if possible.
Requirements
- A SLAC charge number. See your supervisor for
approval and a SLAC charge number.
- An existing SBC phone service in your home (the DSL signal will share
the same wires as the voice signal with no interference).
- A 10BaseT Ethernet interface card
installed in your home computer and
a network cable to connect the interface card to the DSL router that
will be provided by Stanford.
- The ability to configure IP information on
your computer.
If
You Don't Qualify For SBC DSL or Stanford DSL Service
Some suggestions if you don't qualify e.g. your home is
too far from the DSL equipment, you don't have SBC phone service, etc
- Wait. Your DSL request will be resubmitted every 2 or 3
months to see if you qualify. If you do qualify you will be notified and
asked if you still want the DSL service.
- Use the SLAC Dialup Service. This
service is free.
- SCCS has made billing arrangements with one other remote
access vendor:
www.covad.com
Contact them to see if
they can provide any of their services to your home.
- Talk with someone at the company to ensure that their service can actually reach your
home. Give them your phone number or address so they can make a real
measurement to determine if the service is available to you. Don't depend on
web sites that tell you that the service is "available in your area" based on
your phone prefix, etc.
- Once you have found a provider who has guaranteed service to your
home, contact Teri Church, x3176, for help in procurement
processing.
- SLAC credit cards are not acceptable for paying for these types of
services. See:
http://www2.slac.stanford.edu/comp/net/dsl/pcard.htm
-
SCCS will not provide technical support for non Stanford
DSL services, including installation coordination.
General
Information
- Check with your Supervisor/Manager
Check with your Supervisor or Manager to obtain a SLAC charge number to
pay for your DSL service. Work with him to determine which service
to choose based on cost, type of work you'll be doing at home, the bandwidth
and IP addresses needed, etc.
-
Check with your Desktop Admin
Check with your Desktop Admin person before ordering DSL. He
can provide advice and help you with any upgrades/patches, configuration, software, or hardware issues that
might come up.
- Installation information
It normally takes 2-4 weeks to complete an installation. The
time it takes depends on DSL availability to your neighborhood and
home, the backlog of work already scheduled, the manpower available,
etc.
You will be notified by email what your
installation date is and when you need to be home during that time.
- DSL charges may appear on your home phone bill
Check your phone bill
each month to see if any DSL charges appear on it. Do
not pay any of the DSL charges. Just pay your normal part of the phone
bill. If you see any DSL charges on your phone bill send email to:
dsl-admin@slac.stanford.edu
-
Limited support
The amount of support that SCCS can provide for DSL is limited because
these services are not controlled by SCCS. See the DSL
Support statement for more information.
Ordering DSL Service
The SBC Express service is the least expensive
service, a cost savings for SLAC, and is quite adequate for most user's
needs. It is very rare that the higher speeds are needed for everyday internet
use. Also, you may not qualify for the higher speed services depending on how far your home is from the phone
company DSL equipment. If that is the case you will be given the lower speed
service instead.
Some Stanford internet services, such as the Stanford
Library Subscriptions, are available only through Stanford DSL. Care
should be taken when choosing Stanford DSL versus SBC DSL if you will be using
certain Stanford internet services.
Work with your Supervisor/Manager to understand your
requirements. Then choose the type of service you want from the chart below
and complete the DSL
Service Request Form.
See the
SBC Business DSL
and Stanford DSL web
pages for additional information.
Note concerning low advertised prices for DSL:
SLAC's central billing for SBC DSL services (where DSL services are billed
directly to SLAC rather than the charges showing up on the users home phone
bill) requires us to use the SBC Business DSL choices. These may or may not
include promotional prices and are usually higher than the Residential prices
because of how taxes and other charges are dealt with when a vendor deals with
SLAC. Also, many of the very low prices that are advertised may also
include conditions and requirements that the home user must include, and pay
extra for, on his home phone service and may not extend to the SBC Business DSL
choices.

Canceling or changing an Existing Service /
Moving To A New Address
- To cancel an existing DSL service send email to
dsl-admin@slac.stanford.edu
with the date you want your DSL service cancelled. Also return
your DSL router/modem to Ken Martell, Bldg 050 Room 375, x3804.
SBC normally requires that you have your DSL service
cancelled before they will cancel your phone service.
- To change an existing DSL service i.e. you want
to change from the Stanford DSL service to the less expensive SBC
Express service....you will have to first cancel the existing service
and than request a new DSL installation for the new service. There
is no such thing as a simple transfer. Send email to
dsl-admin@slac.stanford.edu
and we will help you with coordinating this change.
- If you are moving to a new address and want DSL service at
the new address you should request a new DSL installation by filling out the
DSL Service Request Form
after your new SBC phone service is up and running. If you send in the
service request before the service is actually up and running the request will
be bounced back and delay the installation date. Don't forget to cancel the DSL
service at your old address.
Reporting Problems
There are two types of DSL service that SLAC supports.
Stanford DSL and SBC DSL.
Users with a DSL IP address beginning with 171.66 have Stanford DSL.
All other users have SBC DSL.
Stanford DSL service
problems should be reported to 650-723-1611
This number is staffed Monday through Friday, 8 to 5. After
hours and holiday trouble calls are answered around the clock by University
Operators who refer system-wide problems to on-call repair technicians
immediately and individual user problems to the Systems Control Center at the
start of the next business day.
Before calling power cycle your DSL router
and see if this solves the problem. If it doesn't, note the condition of
the status lights and write them down. The Power and Status lights should be
solid green after a minute or so. If they are, try your DSL connection
again. If you still can't make a connection
call for service and report the status of the lights
and your IP address information. Ask for a case number and the name of the
person you are talking to. Write this information down for future
reference.
Visit Stanford's Trouble Reporting web page for more info:
http://commserv.stanford.edu/support/assistance.html
SBC DSL (PacBell
DSL) service problems should be reported to SBC Technical Support at
1-877-722-3755 or go to
SBC Online Technical Support.
Before calling for
service reboot your computer and power cycle your
DSL modem and/or router and see if this solves the
problem. If it doesn't, note the condition of the status lights
and write them down.
Call for service and report the status of the lights and your IP address
information. Ask for a case number and the name of the person you are talking
to. Write this information down for future reference. You
will be asked for a 'billing number' or a 'bill to' number which is 650 926
