Except that the ISDN solution won't work when traveling. Most of my
dial in happens from out of town. Another option might be to contract
with a private network, e.g., Compuserve, and establish a connection
from their net to the company LAN. This addresses the out of town
situation, but (usually) without the bandwidth provided by ISDN.
On a few occasions we've actually intalled an ISDN line for a one day
demo. It actually worked! (I was afraid the telco wouldn't get the
switch configuration right.)
Another option, appropriate in some situations, is to establish a
server connected to the Internet completely separate from the company's
internal LAN. This can support some needs, such as demonstrations, but
probably won't suffice for checking email. An "outdial" capability on
such a system, configured to use a hard wired connection, could enable
terminal sessions.
