What's the role of ISDN in telecommuting?
ISDN (Integrated Services Digital Network) is a kind of phone service
offered by most local telephone companies. It has many benefits, but most
important is the ability to carry one voice and two high-speed data or
video communications channels over existing copper wire in the home. This
generally means there's no need to install new phone lines to give
telecommuters the separate voice and data lines they often need. The cost
of ISDN service is generally less than the equivalent number of separate
lines. However, ISDN is not universally available in the US and other
countries; thus, telecommuters and their employers can't always get access
to it when needed. Also, there are one-time equipment costs for the
special phones and for the devices needed to connect PCs to ISDN lines. On
balance, it's a technology that should be considered but may not always be
available, or cost-effective even if it is available.
