[comp.dcom.telecom] ATT ISDN Set Question

clark@ssc-vax.boeing.com (Roger Clark Swann) (11/01/90)

Here at the Big 'B' most all of the secretarial stations are equipped
with an ATT ISDN 7505 set. That's the one with the multifuction
display. Behind these sets are 5ESS switches, everything being
purchased from and integrated by ATT.  One of the functions of the
display on the 7505 is a clock/calendar. The recent change from
daylight time back to standard time brings the following question:

  Why isn't the clock display in the station set slaved off the real
  time clock on the switch (5ESS) such that the stations are updated
  at least once every 24 hours? 

These sets are powered from the local 120V outlet through a transformer 
and when there is a power outage, the local clock/calendar gets
trashed, the result being that someone must set the clock manually at
each station. I would like to see a *clock sync* data packet sent out
over the ISDN interface to each station that would set the local clock
at regular intervals. Perhaps someone would comment on this.
