SYSTEM DESCRIPTION CENERAL The Nuclear Regulatory Corsission's Health Physics Network (HPN) connects all Nuclear Power Plants ana Fuel Facilities to NRC Regional Of fices and to NRC Headquarters Operatians Center. Its primary purpose is to support the Health Physics operation during a nuclear incident by providing voice coo,rdination between the affected site, the Regional Office and NRC Headquarters Opera-tions Center.
Daily administrative and facsimile traffic will also be sent f
over the network.
f-The NRC Headquarters Operations Center, tne Regional Office, Power Plants and Fuel Facilities on each circuit are connected on a type of " party line" (see Exhibit on following page). Calling may either be Station to Station, Group, or Broadcast to all stations.
SYSTEM FEATURES The HPN provides the following features:
Station to Station Calling - A location may be
" called" on an individual basis by dia:ing the assigned two-digit station code.

O NRC SECTION I
\\r Group Calling - a predetermined group on a circuit may be called by dialing the assigned two-digit code.
The HPN's group code signals all Resident Inspector telephones on that circuit.
Broadcast - a universal two-digit code which when dialed simultaneously sig-nals all stations on a circuit.
This network has a separate code for voice and facaimile broadcast.
Conferencing - the calling party may " conference" stations anytime during the conversation by simply dialing the appropriate code (s).
Any numbe,r of sta-tions may be added in this manner.
Privacy - This feature is achieved automatically as the desired station code is dialed. It permits only those stations selected by the originator to be F.
included on the call. All other stations are " locked out" and will hear a steady high pitched tone if they lift their receiver. Privacy is maintained until the originator hangs up.
Circuit Busy Lagg - The Resident Inspector's telephone will be equipped with this lamp to provide a visual indication of circuit availability. The circuit buttons on the telephone at Regional Offices and NRC Headquarters Operations i
t Center will serve the same function.

~
Privaev Override - NRC Headquarters and Regional Offices may seipe a circuit
- by pushing the non-locking privacy override button on their telephone. Oper-ation of the override button places a short burst of high level tone on the circuit, removes the station busy tones and darkens all busy lamps.
The overriding party may then place the call. If the overridden parties have not hung up, they are disconnected as the overriding party begins to dial.
INTE R-C ircu i t Switching The ability to dial from one circuit to another is provided by this feature.
Th is is acccmplished by dialing the appropriate interconnect code. An inter-connect code is a unique two digit code associated with each circuit, used to gain access to that circuit from other circuits.
Specific dialing instruc-([
- tions for this and all other types of calls are explained in Systems Operations. The particular interconnect code for each circuit can be found in the Directories section of this manual.
Error Correction - The HPN includes an error ccrrection feature. A complete explanation of this feature is explained under Systems Operations.
FACSIMILE Transmission - Customer provided facsimile (FAX) machines are lo-cated at NRC Headquarters Operations Center, Regional Offices and each Resident Inspector's Office.
A switch will be provided allowing the FAX machine to be used on the HPN circuit or commercial circuit.

SYSTEM OPERATION General As soon as the telephone receiver is lif ted, the calling party may dial. NO DIAL TONE IS HEARD.
.I l
The calling party does not hear an audible ringing signal after dialing the l
desired code (s).
Ringing is heard at the called station to indicate an i
i incoming call. This ringing stops when the telephone is answered or at the end of thirty seconds. Even though the called telephone stops ringing, it can still be answered since the calling party may be waiting on the c ccuit. The calling party may, however, dial again if the call has not been answered in
(*
approximately 30 seconds.
s Many locations have more than one telephone associated with a station code.
In these cases af ter one of the telephones is answered, ringing will continue the others until they are answered or the ringing times out.
There is no at privacy between telephones sharing the same code.
To insure the circuit is no: in use, challenge phrase such as " Circuit busy?" may be required if a
ycur telephone has no visual busy indication.
An automatic time-out period of six seconds is provided on the HPN to prevent a tie-up if only one digit has been dialed. This means that the desired code must be dialed within six seconds or the call will not complete.
