This and many other DDS features directly affect what sort of response
time you get at a remote location... Email on this subject would get
VERY long, but any programming slips in design that do not consider
remote sites, will cause response time to really lag... Local and remote
response times can be very different since the local response can appear
to be very quick, but this is "masked" by the blinding speed of a local
controller vs large complex screens wandering down a telephone link...

Communications tuning takes a good bit of experience and knowledge of
equipment, as well as some system tuning to help the situation...
Program design has a heavy bearing on how well the remotes work.
