These are generally remote access servers. Some call them RAS, some call
them NAS (network AS) but they're all the same thing for the most part. In
short, they provide access to the LAN via dial-up technology. These boxes
usually have digital modem cards (the better ones do anyway), which provides
high port density and support for 56k analog dial-up since there is one less
digital-to-analog conversion as a result of the modems being of the digital
variety.
The AS5300, just a fantastic box, has the T1 controllers built right in so
you don't need a DSU. Just plug the T!(s) into the controller ports and
away you go. With this technology, you can get either 23 or 24 dial-up
circuits per T1 depending on whether the T1 is channelized (CAS=in-band
signaling for 24-56k connections) or Primary Rate Interface (PRI=out-of-band
signaling for 23-64k connections such as BRI ISDN).
Hope this helps!

Subject: access servers? [7:10449]
I went to the Cisco homepage and looked at the list of products.
I saw Cisco Access Servers. What kind of hardware are those?
