What is the scope of this FAQ?
This FAQ is an attempt to answer some of the more common questions that
are asked and answered in the LI Cable Modem User's eGroup (lioptonline).
Most of the info presented here was taken from past posts and is
considered to be reliable. I am not as technical as some of the people in
the group, so I will not get too technical here. If you have a question of
a technical nature, please post it to the group, as we have some very
sharp people who are more than happy to help you.
Thanks to all the members of the group for their frequent and informative
posts. You make this group a valuable resource!DISCLAIMER: All info
posted in this FAQ and on the LI Cable Modem User's eGroup is used at the
readers' own risk. While every attempt is made to make sure the
information is reliable, we cannot be held responsible for any use or
misuse of information that you get from these FAQ, or from actual posts.
Is this group only for people on Long Island, or
can anyone join?
Anyone who has an interest in cable modem usage is welcome to join the
group, no matter where you live...even if you don't currently have the
service in your area. The group, however, was primarily created to deal
with the issues of Long Island's Cablevision Optimum
Online (OOL) service. Recently, as OOL becomes available in other
areas (i.e. NJ, CT, etc.) we are seeing members from those areas, which is
not a problem. Also now service is added in parts of Brooklyn. www.optimumonline.com
does not have accurate listings we suggest calling the WIZ directly or
Cablevision.
Why is this a closed group with no
"hotmail", "yahoo", or similar free email accounts
allowed?
Since it is easy for someone to be abusive when they are anonymous, only
people with a traceable email address are allowed to join. Besides your
email address, only the info you supply to egroups is visible to others
when you post.
What kind of people make up this eGroup?
Some members are very
savvy technically. Many of us have a good working knowledge of computers,
Windows, and communication protocols. Others are very knowledgeable in NT,
Linux, and other operating systems. Some of us know very little about
computers. Don't be shy about asking a question, as there is a very good
chance that you're not the only one who doesn't know the answer! This is a
very friendly group, and you will not be "flamed" for asking a
question.
What, if any, are the rules for posting?
The only rule here is to treat other members with respect. Personal,
hurtful attacks will not be tolerated. Please don't get on someone's case
because you perceive they are not as intelligent as you think they should
be. Adult language is OK, but please remember that we are in mixed company
(age, race, sex, etc.), and that everyone has different standards...so
let's not get raunchy.
Some guidelines:
When responding to a post, please try and remember to clip the eGroup ads
from the top of the original post.
Include only the pertinent parts of the message you are responding to.
This makes reading the email and digests much easier.
Take a look thru the posts to see if a question has been asked and
answered recently before posting the same question again.
Does this eGroup have any affiliation with
OOL and are there OOL people here as members?
The moderator of this eGroup has no affiliation with OOL, other than being
a subscriber. From what I hear, OOL people DO subscribe to the group. I
have no way of knowing who they are, but hopefully they use their
affiliation to give us some factual info. We welcome OOL participation, as
that can only lead to a more informed group and a better working system.
(UPDATE: There are now several OOL employees who are group members.
They have been very supportive & are frequently solving problems for
us. In addition, they give us great insight as to the workings of the OOL
network.)
I read about "KB/sec" and
"Kb/sec" and it's very confusing. Is there a difference between
the two?
Yes, there is a difference.
K = Kilo, or 1000*
"B" (Big B) = Bytes
"b" (small b) = bits
8 bits = 1Byte
* NOTE: When speaking in terms of data transfer, 1KB = 1000
Bytes. If you are speaking in terms of data storage, then 1KB is
equal to 1024 Bytes. Here's a better
explaination .
In other words, a download rate of 350 KB/sec is equal to 2800Kb/sec.
As an example, when you are downloading something via the Netscape
browser, a standard 56K modem will typically do it at a rate of about 4 or
5 KB/sec. as displayed in the download box.
Use caution when comparing the speed of DSL to cable, as DSL ISP's usually
quote in Kb/sec, which make them sound faster. When you see such a quote,
you must divide by 8 to get a compatible rate in KB/sec.
How fast can I expect to DL data over the
internet with an OOL connection?
While "mileage may vary", you can expect DL speeds to be between
250 KB/sec and 600 KB/sec, with the average reported speed to be about 400
KB/sec. This translates to about 25 seconds for a 10 meg file. Your actual
speed will depend on the number of people who are using the service in
your area, and general internet traffic. These figures are for the new
DOCSIS compliant modems. This is an increase from what the FAQs had
previously stated. OOL seems to be upgrading it's network to keep pace
with their growing number of subscribers. We thank them, and hope this
trend continues.
Does OOL have a download (DL) or upload (UL) cap
in place?
There is no official word about a DL cap, but OOL does have an UL cap of
128 KB/sec.
How is the cable modem hooked up to my PC?
Typically, the cable modem is an external unit with 3 connections on the
back. One hooks up to a separate "brick" type power supply. The
second is a male "F" connector (like the one on your TV) onto
which you screw the CATV coax. The third is an RJ45 jack which looks like
a large telephone modular connector. You insert a CAT5 patch cord into
this jack (usually supplied with the modem), with the other end going to
the Network Interface card (NIC) in your computer. If you don't have a NIC
card in you computer, you must buy and install one (about $20), or buy an
adapter which connects to one of your USB ports and has an RJ45 jack on
it. The NIC card should be a 10BaseT or a 10/100BaseT card. The 10 refers
to the transfer rate of the card in Mbps (million bits per second) with
10/100 capable of 100Mbps. For use with the cable modem, 10BaseT is
sufficient since 10Mbps exceeds the speed of the modem. The "T"
refers to twisted pair, which is the type of cable that is used with the
RJ45 connector. In my opinion, and from posts I've read, you are better
off with a NIC card rather than the USB adapter as the NIC card seems more
reliable.
Do I have to run a separate CATV cable for the
cable modem?
It is usually best to cut the cable and use a good quality splitter so
that one half feeds the TVs in the house, and the other half goes directly
to the cable modem Use RG6U cable, and do a clean job making up the
connections using good F connectors and a good crimping tool. If it is
very difficult to run a new cable to where the modem will be, I have had
success using a splitter near an existing TV cable and running a new cable
to the modem. Again, results will vary, with the dedicated route being the
better choice.
Will I be able to use my Optimum TV while using the
cable modem?
Yes, use of the cable modem has no effect on the TV, and visa versa.
Can more than one PC/Mac share the same cable
modem?
OOL will tell you that you must get a separate modem for each PC/Mac you
want hooked up to the internet, but many people "share" their
cable modem simultaneously with 2, 3 or more PCs/Macs in their home. There
are several ways in which this can be done, the most simple being to use
the ICS feature of WIN98. You can also use software such as Wingate
or Sygate to
share the connection. Another alternative is to buy a hardware device
called a cable router which plugs into the cable modem, with the PCs
connecting to it. Linksys
, Ugate , and others make
these, and they cost about $150 to $300 depending on what and where you
buy. Whatever method you use, you will need a NIC card or USB adapter for
each computer.
I presently rent a LanCity / Terayon modem
from OOL and have been told that I need to exchange it for a DOCSIS
compliant modem before July 15, 2000. What's that all about?
If you have a LanCity modem, you should have received a letter from OOL
explaining the situation. Basically, OOL is "upgrading" their
system to the DOCSIS standard. Right now they are running more than one
system, one IS DOCSIS compliant, and the others ARE NOT. Evidently, on
July 15th., they plan on decommissioning the old system that is used with
the LanCity, at which point those modems will no longer work. Evidently,
if you have a Terayon TeraPro modem, it will continue to work past July
15, until they phase that one out too. Their goal is to become 100% DOCSIS
compliant.
From past posts, it seems that there are 4 modems available at the WIZ for
outright purchase, or continued rental. The old style 3Com
CMX, the newer 3Com
"Shark Fin" (because of it's looks), the the
Motorola SurfBoard, and the Terayon
TeraJet. Each costs the same, and from what is reported in the group,
there seems to be no clear cut winner in terms of performance or
reliability among the three. In other word, one will work as well as
another. All 3 of these modems will probably be slower than what you are
used to with the LanCity or the old TeraPro, but you will have no choice
other than to use the new ones after July 15th. if you have a LanCity.
In some cases, OOL will deliver a complete package to your home which
contains the modem, splitter, NIC card, RG6U cable, and a cat5 patch cord.
This seems to be the case in areas where the service is first being
offered.
Can I run an FTP, HTTP, or a mail server from
my OOL connected computer?
Technically, it is possible, and is done. OOL
Terms of Service (TOS) has recently been ammended (see Sec.32) to
state (in part) that:
"Examples of prohibited uses include, but are not limited to, running
servers for mail, http, ftp, irc and dhcp and multi-user interactive
forums."
Does OOL have a news server?
Yes, OOL has a newserver for OOL subscribers and it's included with your
subscription. It is located at "news.optonline.net". They have
about 35,000 newsgroups available, DL speed is very good (as would be
expected), and retention time is about a week for the non-binaries groups,
and a couple of days for the binaries groups. Unfortunately, there seem to
be more incomplete posts in the binaries groups lately. IMO, not bad for a
package deal, but they could do better. There are other subscription new
servers (i.e. Altopia , Newsguy
, Supernews , Usenetserver
, Newscene , etc.) which you can
subscribe to (for a fee) if you need a more complete service.
Where can I find more info on setting up a home
network?
Besides past posts from this forum, Tim
Higgins has a great site with lots of info on LANs, sharing, and
security. The Linksys
site also has good info on networking. Of course, you can always do a
web search for more info.
Speaking of security, are there any risks
associated with using a cable modem?
Any time you're connected to the internet, whether thru a regular modem
via your phone line, a cable modem, or DSL, you leave your computer files
vulnerable for others to peek at, alter, copy, or destroy. When you make
use of a service such as cable, or DSL, you can be even more vulnerable
due to the fact that you are connected full time, and the people who are
doing their mischief can do it much faster. There are, however, safeguards
you can take to help secure your computer against most assaults. A basic
understanding of TCP and the various communication protocols will go a
long way toward protecting your files. Programs such as BlackICE
Defender, Zone Alarm (free for
private use!), and Norton
Personal Firewall 2000 will help . Hardware firewalls can also shore
up your protection. Actual configuration techniques are beyond the scope
of this FAQ, but there are sites such as
Gibson Research "Shields Up" and Secure-Me
that will evaluate your computer setup and let you know how you rate in
the security department. Again, Tim
Higgin's security section has lots of good info, and there is a wealth
of knowledge from some very technical people in pasts posts to the eGroup.
