Quick question for all you ADSL users out there - does the ADSL connection work similarly to an ISDN connection, in that when the modem is active one can still use the telephone?

Yes, I is a n00bl3t when it comes to ADSL.
 
Yes ... the voice part of your line is seperated from the data portion.
 
Thanks tibby.dude - much appreciated.

A few pointers concerning ADSL

a) Don't sign a 24 month telkom contract
b) Telkom supplied Marconi modems are the devil's hind t i t.
c) USB modems are also the devil's hind t i t.
d) Netgear/Dlink/Billion and Planet gear is recommended
e) Telkom takes two bussiness days to activate your account and they stick religiously to it.
f) Buy ADSL microfilters beforehand from your local Telkom chopshop as they don't supply it or the technician does not have any with him when he comes to install it.
g) Be physically present during the installation and don't depend on your girlfriend or mother or grannie to actually verify that the technician actually tested the link.
g) 3GB is not enough

That about covers it.

Well, with ISDN you have two lines, so if you use the one for dail-up the other one is open to voice. But then if you dual connect you cant call and when your not connected you can use both lines for calls. ADSL is always on (well with telkom its mostly), and you always have 1 telephone line. So if you are connected or not you can call.
 
Thanks tibby - I've learn't my lesson with contracts (Sentech - *shudder*).

As for the gear you mention, I am looking for an ADSL modem that will work with either Smoothwall or IPCop. I've used both, I have the machine and would prefer to carry on with such a setup as both of them have some very nice bandwidth meter mods.

What budget are you looking at ???.

Personally I use a Netgear DG834 (modem/router with 4 port 100Mbps) (the non-WiFi model) and it has always worked very well for me (no mysterious funny stuff when Telkom changes their line settings).

It runs embedded Linux and uses iptables and Zebra so it is rock solid from that point of view except that the case looks rather boring in stock appliance white.

There are cheaper stuff out there but if you look at the Taiwanese or Chinese makes they have a product refresh every 3 months and orphan the old stuff far too quickly for my tastes.

I use the same (cept the wifi one) must say its probably one of the best I have used (compared to the planets, telkomcrap etc)
 
Best way out of a Telkom 24 month contract is don't pay. They disconnect you and then you need to settle the bill, pay R500 deposit and get a new line, sell the Marconi modem and get a real one.
 
I have had a lot of disconnections on my ADSL line and realised it was because I calls were being made. When they installed the line they assured me that I did not need a microfilter but now it is clear that I do. I live in Pretoria but don't know where I would be able to buy microfilters. I also want to know if I need one for both the telephone and ADSL or only for the phone.(They are in different rooms)

Thanx

as far as I know everything but the DSL must get the filter, phones, fax, alarm etc.
 
can anyone tell me where in pretoria I can buy the microfilter?
 
This may seem a stupid question, but do u have to call in to an ISP like with dial-up? As far as I know you have to, but will it have to be a local number? I live in Worcester, so I wouldnt want to have to call Cape Town for my ISP.

In ADSL your connection is to the nearest exchange (via your telephone cable) and from there it goes to SAIX and then to your ISP.

There is no telephone number you dial as your connection is always on and you only provide a login name and password when you ADSL modem or Windows "dialer" initiates the connection.

You only pay a flat fee depending on the package (192K,384K or 512K) and not how long you have been on.
