RE:  Campus Phone System Privacy Consideration

In May 1999, Communications Resources will be making changes to the campus
telephone system to keep it current with the public telephone network. Campus
telephone subscribers will be affected by the changes in that when placing
off-campus telephone calls, their UC Davis phone numbers may be displayed to
call recipients. Display of a caller's phone number depends on whether or not
the call recipient's phone company offers Caller Identification (Caller ID). 

Changes Related to Outgoing Calls
Prior to implementation of the changes, the Federal Communications Commission
(FCC) requires that Communications Resources offer its customers the option of
blocking Caller ID from outgoing calls. This can be done either by blocking
Caller ID on all outgoing calls or by blocking on a per-call basis.  

A decision to block Caller ID means that phone numbers will be blocked to both
on-campus and off-campus call recipients. Since most calls processed by the
campus switch remain internal to the campus, normal calling patterns should be
considered when assessing the need for privacy.

Please note that individuals who do not choose to block Caller ID on all
outgoing calls will be able to invoke blocking on a call-by-call basis by
using a special code, *67, prior to dialing the destination telephone number.
Also, individuals who choose to have Caller ID blocked on all calls will still
be able to invoke unblocking on a call-by-call basis by dialing *82 prior to
dialing the destination phone number. 

Changes Related to Incoming Calls
Campus telephone customers with multi-line sets will also see some changes on
the display for incoming calls. Currently, they receive Caller ID when the
calling party is located on our telephone system. The telephone system changes
will expand Caller ID on multi-line sets to include all incoming calls, on or
off campus, that do not have Caller ID blocked. Customers with multi-line sets
will notice that the display generated from off-campus callers will change
from general information, such as "DIDV" to the caller's telephone number,
including the area code. If the caller has Caller ID blocked, however, the
message displayed will be "BLOCKED" or "PRIVATE".  Caller ID is still relatively
new, and long distance telephone companies have not been consistent with the
implementation of this feature.  Therefore, the information displayed on each
call may vary.  Campus multi-line customers will also notice the same changes
for campus callers. Campus telephone numbers will no longer be automatically
displayed because campus callers will now be given the option of blocking
their Caller ID information.

Action Required
Communications Resources is requesting that campus departments consider the
needs of their faculty and staff to determine whether they want to have their
numbers blocked on all outgoing calls. Department Area Telephone
Representatives (ATR) have been notified of these impending changes. No action
on your part will indicate that your department's telephone numbers will be
displayed to the called party.  Should any of your staff choose to have their
telephone numbers blocked at implementation, please forward your departmental
list of those individual telephone numbers to your ATR by May 7, 1999.

Service Charges
Communications Resources will honor the initial choices that are made by May
7, 1999, at no charge.  Departments that wish to have numbers blocked or
unblocked after May 7,1999, will be able to do so through the normal service
order process for which there is a reconfiguration service charge of $21 per
subscriber line.

For further information please call your Communications Resources Customer
Service Representative. If you are not sure who your designated Customer
Service Representative is, please call the Communications Resources office at
530-752-4603.
