That is adsl over isdn. Thought to only COMMON flavours were adsl async up/down and sdsl sync up/down freq ranges.
SEEMS YOU CAN USE A BRI WIC!!!!!!! >>>>>>>>>>>>>>>>>>>>>>>>> Developed by Ascend Communications (acquired by Lucent Technologies), ISDN Digital Subscriber Line (IDSL) transmits data digitally across existing ISDN lines, at a rate of 128 Kbps. The benefits of IDSL over ISDN are that the former service offers always-on connections, transmits data via a data network rather than the phone companybs voice network, and avoids per-call fees by being billed at a flat-rate. http://www.cisco.com/en/US/partner/tech/tk175/tk349/technologies_q_and_a_ite m09186a00800946d3.shtml Q. What is IDSL? IDSL is a cross between ISDN and xDSL. As with ISDN, it uses a single wire pair to transmit full-duplex data at 128 Kbps and at distances of up to the Revised Resistance Distance range of 15,000 to 18,000 feet. IDSL also uses a 2B1Q line code to enable transparent operation through the ISDN "U" interface. IDSL is essentially a leased line ISDN Basic Rate Interface (BRI), or an ISDN BRI that is not switched and does not contain signaling (a D channel). IDSL and ISDN BRI use the same 2B1Q line modulation. On the router, this equates to putting the BRI interface in a leased line configuration. The line can be configured for a speed of 64 Kbps, 128 Kbps, or 144 Kbps. The frames that are going across the wire are standard High-Level Data Link Control (HDLC) frames. IDSL can be configured with Point-to-Point Protocol (PPP) or Frame Relay encapsulation for the leased line BRI interface. The easiest way to think about it is as if the BRI interface was a slow speed synchronous serial port. Also, existing Customer Premises Equipment (CPE) (ISDN BRI terminal adapters, bridges, and routers) can be used to connect to the central office.

No. The Cisco 2500 series does not support IDSL because its BRI hardware does not support channel aggregation. Q. Does the Cisco 2600 support IDSL? Yes. IDSL is currently supported with the ISDN WAN Interface Cards (WICs) and network modules when they are configured in leased line mode. Q. What routers support IDSL? The following routers support IDSL: 800 b Cisco 801-805 ISDN, Serial, and IDSL Routers 1600 b Cisco 1600 Series Routers and WAN Interface Cards 1720 b Cisco 1720 Modular Access Router 1750 b Cisco 1750 Modular Access Router 2600 b Connecting WAN and Voice Interface Cards to a Network Martijn -----Oorspronkelijk bericht----- Van: Ryan Finnesey [mailto:[EMAIL PROTECTED] Verzonden: woensdag 13 augustus 2003 7:53 Aan: Jansen, M; [EMAIL PROTECTED] Onderwerp: RE: VPN Best Hardware to use?

[7:73793] You are right it is a service offering. Right now, we are using ISDN dial-up and would like to move to a full time connection. We would not be using the customerbs connection but will be installing a 144K IDSL or 192K SDSL line. What I am going to do on Friday in the lab ( If we get the lines from Covad on time) is use a 7200 at the head end and a 1700 on the other end run the IPSec and NAT on the 1700 and see how that goes. The only problem is I cannot find an IDSL WIC on CCO I only see an ADSL and SDSL. Ryan Message----- From: [EMAIL PROTECTED] on behalf of Reimer, Fred Sent: Mon 8/11/2003 10:02 AM To: [EMAIL PROTECTED] Cc: Subject: RE: VPN Best Hardware to use? [7:73793] I would certainly hope that the remotes wouldn't use different platforms. I don't know the business model, but it sounds to me like it's some kind of service offering or something. Maybe they have a 2000 site Frame Relay network used to offer a service or something, and they want to switch to something more economical. Instead of paying monthly circuit fees, pay a one-time hardware cost (assuming they don't own the FR routers at the customer end) and use the customer's Internet connection. Why in the world would you want different hardware at each customer site in that situation? Standardize on one hardware platform, and build the cost of that hardware into the business model... If that's the case then the cost of a 3005 can be justified in a small number of months, depending on your FR cost. Certainly you would recoup your cost and start making more money, due to less operating cost, relatively quickly. Now, if this is something else, like a company with 2000 offices throughout the world, then I can see your point and you may end up with different requirements. But, that's not how it sounds so far.

[7:73793] Despite all hw issues, you really need to - describe the business req's first - translate to technical req's (you are talking 2000+ sites) And you will see that you'll need more than one platform for de Remotes. Dependig on your hierarchy concerning - messaging - authentication - client-server - webapps - desktop/register maintenance/management - security man You will need to or may want to build an hierarchical design. Keep in mind that differen platfroms use different (HQ) fail-over or 2nd ip techniques. Martijn -----Oorspronkelijk bericht----- Van: Ryan Finnesey [mailto:[EMAIL PROTECTED] Verzonden: zondag 10 augustus 2003 4:36 Aan: [EMAIL PROTECTED] Onderwerp: VPN Best Hardware to use? [7:73793] I need to setup VPNs to about 2000 sites. Each site will have an IDSL line installed that will be used to connect to monitor network devices and servers. Some of the remote networks will be using the same network block. I am looking to know what the best hardware to use on each end is. On my end, would it be better to use a PIX or a 3030? On the remote end, I was looking at a PIX 501, SOHO 91 or the 831?
