Re: ISDN is the future
said by patcat88  :So whatever happened to ISDN?  It’s very common in the business environment to find 3 BRI ISDN’s being used for teleconferencing. BRI ISDN is also used extensively as a backup for the leased sub-rate data lines used by ATM machines.

said by belushi :Virtually all decent sized comapnies use ISDN PRIs for their bigger voice trunks instead of T1s. Actually the current trend is to drop the PRI’s and migrate to DS1's into channel banks be they an external CB or part of the subs switch or to VoIP over DS1’s DS3’s or Metro-Ethernet.
Heck simply going from a PRI to a T gains one 64K as the D channel is no longer needed and that bandwidth can now be rolled into the overall pipe.

True... of course, when this Ad came out, the internet was still more of a concept and experimentation. They probably weren't even considering it for use as it is sometimes used today.
Though, I heard that digital phone line service has a great quality in using it for voice data. (I'd rather have ISDN or a T1/Partial T1 than satellite for the latency... and the fact that I wouldn't get in trouble for downloading or having multiple people view webpages at the same time. -.-) |

ISDN is alive and well in the United States and abroad. Maybe not ISDN BRIs so much but ISDN PRIs are an integral part of voice/data communications. Virtually all decent sized comapnies use ISDN PRIs for their bigger voice trunks instead of T1s. ISDN is going no where and is here to stay for a while.
Just because it isn't used in the home for Internet connectivity doesn't mean it's not widely used in other consumer spaces. |

Wow. It's always fun to see some of the old advertisements in old magazines. (That thing's older than I am!)
What happened? Cable was seen as a viable way to have an internet connection, as well as having the ADSL system with phone lines.
T-1 happened as well, and now there's T-3 and even more.
Isn't interesting how things change in like, a little over 20 years? xD |
