Re: A great sign...
said by RedSurf  :In order to use ISDN, the local phone company has to provision the line for ISDN. This is not a regular POTS line as you imply but needs dedicated equipment at the local CO for ISDN. So it is not possible to just get an ISDN modem and dial up an ISDN supported ISP. Without the phone company provisioning the line for ISDN you have no ISDN. Sorry, I wish it was that simple. IDSN is a phone line, you can dial anyone you want and have a voice conversation with them, therefore you need to have local/long distence/etc on it, even if all you do is call one number (the ISP). IDSL is similar to IDSN, but it isn't a phone line, there is no concept of phone numbers, the only thing it can do is put you on the internet. IDSL would be a phone line, that when you pick it up, it is a direct connection to your ISP, you can't prevent or change the number that is dialed. IDSN is like a normal phone line, except its digital, and you get the benifit of having 2 lines. | |

It is a phone line, but it is a special phone line and therefore requires special equipment.
ISDN uses the same copper pair that already goes to your house. The equipment at either end (phone company and you) is different. When we talk about routers, most have the ability to do dialup for internet as well as convert the ISDN into two POTS (plain old telephone system) so that you can plug your regular phones into it and use them for voice. | |

IDSN is like a normal phone line, except its digital, and you get the benifit of having 2 lines. IDSL is DSLAM based service using 2B1Q ISDN technology vs. DMT to transport the data between the DSLAM and end users modem. IDSL does not require a NT1 or router as it is an always on point to point connection.
ISDN is a switch based technology that requires a NT1 or router to set up the call over the D channel with transport over one or both B channels.
Both technologies are compatable with standard SLC system remote terminals allowing CLEC's to offer DSL like service out of a ILEC RT without having to place a remote DSLAM.
