In the late 1990s, when many of these networks were built, they weren’t expected to carry e-mail traffic or support rich applications. When the only traffic on the wire consisted of terminal sessions to an AS/400, maybe 128Kbps really did fit the bill. Now, of course, the playing field is much different, but the prices are not. Today, it’s not uncommon to find a frame-relay network of reasonable size and geographic spread priced at $30,000 per month. For overseas sites, the prices increase exponentially.
