Hi,

I'm searching for an external ISDN modem.
It must be connected to a SeeHawk
http://www.darvision.com/products/seehawk/seehawk.html
I have to be able to dial in on the machine both with an ISDN as an analogue
modem.

This is what I read on the USR website:

The Courier™ I-modem™ brings ISDN connectivity and analog compatibility
together in a single device. It is the ideal desktop solution for high-speed
corporate LAN connections, graphic-intensive Internet access, data-intensive
file transfers and access to online services. With its built-in V.90 56K
modem, Courier I-modem makes an ideal choice for small offices that want to
offer employees 56K* remote access. I-modem functions as an inexpensive 56K
x2 or V.90 digital host (required for 56K remote access, as well as for 128K
ISDN remote access.)

Courier I-modem
SKU# Description
000698 ISDN with x2/V.90, Analog Device Port and NT1, External
001102 ISDN with x2/V.90, S/T, External
002215 ISDN with x2/V.90, Analog Device Port, V.35 Interface and NT1,
External

What model of external ISDN modem that USR sells is the best solution for my
problem?


Sincere greets,
Maarten.

Firstly, the seahawk surveillance system have it's *OWN* 33.6Kbps modem. But it can also be plugged to an external ISDN modem for faster transferring of data.

What you intend to do is to dial into your camera using Courier I-modem is possible. But you only get to receive the still images from the seahawk cams. If you need to browse your corporate lan, then you must plug the seahawk *TO* your lan, and have your servers provide a way for you to access the seahawk images/videos.

By plugging the seahawk directly to the courier I-modem will not allow you to browse your lan. As you will be dialing to the seahawk surveillance system. Your PC or portable PC acts only as a client. You can save the images etc. But what about the continuous monitoring of your premises? In this case, you must plug your seahawk to your corporate LAN, and you in turn can dial into your corporate computers and access the seahawk from there. This is more feasible and practical.

If you currently don't have a remote access server, then you can get the Courier I-Modem and dial in using it to access your company's computers which not only provides access to your company computers but to seahawk as well. Plug your seahawk surveillance or have it online using the seahawks INTERNAL 33.6Kbps modem on your company's computers (under this setup your company's computers acts as the OPERATOR PC), and you can call your company computers and access everything.

But in my honest opinion, you don't need a Courier I-Modem... the courier I-Modem provides 56K v90 access, true. But in order for it to provide callers with a v90 capability, your telephone lines must be E1R2 lines. Get the 3Com/USR Courier VEverything Corporate Modem (External) instead, so that you can dial in to your company and hook your seahawk surveillance system using *IT'S* internal modem.

You can directly CALL the SEAHAWK, or it can be configured to CALL your PC.

In anycase, sku#s 000698 or 002215 would be a good choice.

This is what I want.. (faster transfers etc..)
So the ISDN modem MUST be plugged to the SeeHawk

....
What are E1R2 lines?

This is the situation:
On the camera site there is an ISDN line, camera's and the SeeHawk.

I want to see the images from anywhere else with the fastest datatransfer as possible (this is why we chose ISDN)

now my problem is:
I want to be able to dialin on the SeeHawk module from anywhere, using both an ISDN as an analogue modem.
So is it possible to log in with a 56k modem aswell as with an ISDN modem on the courier ISDN? and what model ?

An E1R2 line is a kind of leased line deployed here in Asia, Europe, and Latin America. It is a channelized E1 Line running on an r2 protocol. An e1 line is channelized to provide 30 channels. Thus allowing 30 remote users.

I forgot we were talking about ISDN and I assume that you're in the US... so e1r2 doesn't matter to you.

Anyways, all the models of Courier I-Modem can be used. Depending on what country you're in. SKU #001102 is using S/T Interface which is intended for countries outside of the US.

So in short, as I have cited in my answer, if you're in the US, you can go for the two models 002215, 000698... But to be sure, you must give 3com/USR your country of origin or if possible, exact location.

And yes you can connect to your Courier I-Modem using ISDN or v90.

I adviced you get the 002215/000698 models coz I assume that you have an NT-1 Device...

In this part of the deployment, you must consult your particular telco as to the specifics of your ISDN line.

If you don't have ISDN line as of this time, here are the steps you need to do to install your I-Modem:

1. Subscribe to ISDN service;
2. Your telephone company will install a BRI line at your site;
3. Install the I-Modem;
4. Purchase and Install an NT-1 device (if necessary) and connect the cables;
5. Run the modem Config Manager.

Oh I forgot, S/T Interface are also used in US although countries outside the US commonly connect the I-Modem using the S/T interface. . It really depends on your telco...

I'm in Belgium
there allready is an ISDN line

what is the difference between the 3 models ?
0
femson7Commented:
If you want the IN-DEPTH discussion as to their differences, you must contact 3com site in your area.

In summary, there are only two versions of the I-Modem, the U interface and the ST-Interface. The U-Interface has a builtin NT1 device which enables it to be plugged directly to an ISDN jack. While the S/T Interface needs an external NT1 device so that you can plug it in to the ISDN jack.

Can you tell me the specifics of your ISDN line??

As I'd like to further discuss the technicalities with you, my *ANSWERS* to your OTHER questions would be limited as I don't have the specifics of the lines and equipments you currently have in your site.

the Sportster ISDN TA could be a better solution
but I'm, again, not sure wether I can dial in on it both with an isdn modem as an analogue (V90)

I don't think it provides v90 remote access service... otherwise it should have been mentioned
