Abstract How to use your telephone.
FCC Requirements
The Federal Communications Commission (FCC) regulates the connection of terminal equipment to the public telephone network. These regulations are defined by the FCC Rules and Regulations, Part 68. The regulations place the following requirements on users of this equipment:
1. you must notify your telephone utility as follows before connecting the CSL-8308 to the telephone network.
Intention to install an FCC Part 68-registered device:
Name of Manufacturer: Xerox Corporation
Equipment Model Number: Xerox CSL-8308 Voice Terminal
FCC Registration Number: ....
Ringer Equivalence Number: 0.2A
You must also notify the telephone utility when the device is disconnected from the telphone network and will not be reconnected.
2. Connection of this equipment to party lines or to coin telephone service is prohibited.
3. Under certain other circumstances the telephone company may make changes in its facilities and services which may affect the operation of the CSL-8308 voice terminal. The telephone company will notify you in writing before making such changes.
4. If trouble occurs, disconnect this equipment from the telephone line by removing the modular plug from the telphone company modular jeck. You can determine whether the trouble is with the CSL-8308 or with the telephone network by reconnecting your regular phone. If the regular phone works properly, then the trouble is with the CSL-8308 and you should take steps to to get it repaired (see below). If on reconnection, your regular phone does not work , then there is a problem with your line. You should notify the telephone company that they have a problem and request prompt repair service. If the CSL-8308 causes harm to the telephone network, the telephone company may temporarily discontinue service until the problem is corrected.
5. The user may not under any circumnstances attempt any service or repairs on the CSL-8308. It must be returned to the service organization for all repairs (see below).
Description
The CSL-8308 voice terminal is a multi-purpose, CPU-assisted telephone ancillary device, intended for applications in office systems research. Its functions include a number of simple telephone control capabilities.
The CSL-8308 voice terminal is assembled as a research vehicle by the Computer Science Laboratory at the Xerox Palo Alto Research Center. Although it is in full compliance with the FCC regulations that would permit manufacture and sale, the CSL-8308 voice terminal is intended for use only in limited numbers, on the premises of and under the supervision of the manufacturing organization. The instructions in this manual are based on those assumptions.
Installation
The CSL-8308 voice terminal will in all cases be delivered, unpacked, and initially installed by a representative of manufacturing organization. Subsequent disconnection, relocation, reinstallation are simple actions that may be done by the user. No special precautions are required when relocating the equipment.
The CSL-8308 voice terminal comprises the following equipment:
CSL-8308 unit.
Telephone instrument (ITT model 2500M)
Loudspeaker assembly (control unit, loudspeaker, connecting cable).
Loudspeaker interface cable. Plugs on both ends are keyed (see below.)
Telephone instrument interface cable. Plugs are not keyed (see below.)
Telephone line interface cable.
Microphone with attached cable and stand.
AC Power cord.
Ethernet cable, RS232 cable (optional)
The telephone line interface cable is designed to mate the CSL-8308 unit with an RJ12C or RJ13C voice jack, supplied by the telephone company.
The other interface cables are identical except that the plug on both ends of the loudspeaker interface cable includes a key, or projection, on one side that matches slot in the "Speaker box" jack on the CSL-8308 unit and a corresponding jack in the loudspeaker control unit. This cable will not fit in the "Telephone" jack.
The CSL-8308 unit also includes audio jacks to permit conventional audio equipment to be connected either for input or output.
Installation Steps
1. Connect the loudspeaker control unit, containing the volume control, to the loudspeaker by means of the supplied connecting cable.
2. Connect the loudspeaker assembly to the CSL-8308 unit by means of the keyed cable. Plug the keyed end of the cable into the keyed jack, labelled "Speaker Box", on the CSL-8308 chassis. Plug the other end into the loudspeaker control unit.
3. Connect the telephone instrument to the CSL-8308 unit by means of the unkeyed cable. Connect either end of the cable to the telephone instrument. Connect the other end to the jack labelled "Telephone" on the CSL-8308 unit.
4. Connect the CSL-8308 to the telephone network (RJ12C or RJ13C voice jack) using the telephone line interface cable. Use the CSL-8308 jack labelled "Telewall".
5. Connect the Ethernet cable and/or RS232 cable, as needed, depending on the application.
5. Connect the AC Power cable to the CSL-8308 unit. Plug the unit into a grounded wall receptacle (110V, 60 Hz.)
Operation
To operate the CSL-8308 unit, turn on the power switch. Then use the pushbuttons on the attached telephone instrument to perform the following functions. All of these commands should be performed with the telephone handset removed from its cradle. Replacing the handset releases any connections and cancels any of the switching arrangements described below.
Voice from the outside line is always directed to the Line Out A jack as well as to the telephone set receiver. Signals from the handset, microphone, or Line In jacks (when they are connected as described below) are normally directed to the telephone line, to the loudspeaker, and to the Line Out B jack.
When the power switch is turned off, the telephone set will operate as a standard telephone.
Commands
Push "1" to pick up the attached telephone line. If the line was idle, you should now hear the telephone company dial tone. If there was an incoming call ("ringing" is indicated by a flashing red light on the loudspeaker control unit), this action will answer the call.
Push "2" to release the attached telephone line. This will abandon any call in progress.
Push "3" to signal the beginning of a telephone number to be dialed. Then push any sequence of up to 18 digits, ending with the "#" button. The CSL-8308 voice terminal will not immediately dial this number, but will remember it until you invoke the dialing operation.
Push "4" to dial the remembered number. For this to work properly, you must previously have picked up the attached telephone line and obtained a dial tone.
Push "0" to connect the handset transmitter to the outside line, disconnecting any other inputs. After picking up the line (using "1") and possibly dialing a number (using "4"), you must do this in order to converse with the other party.
Push "6" to connect the microphone to the telephone line, disconnecting any other inputs. The microphone now be used in place of the handset transmitter.
Push "7" to connect the "Line In A" audio connection to the telephone line, disconnecting any other inputs.
Push "8" to connect the "Line In B" audio connection to the telephone line, disconnecting any other inputs.
Push "9" to cancel any special switching, pick up the outside line, and connect the telephone handset transmitter and (DTMF) pushbutton signal generator to the telephone line. The telephone will now perform in most respects as a conventional telephone. Replace the handset in the cradle to release any calls and cancel this configuration.
Push "*" to connect the outside telephone line (instead of the local input) to the loudspeaker.
Trouble Shooting and Maintenance
The CSL-8308 voice terminal is supplied to its users by the manufacturing organization for the purposes of evaluation only. It may removed for any reason by the manufacturing organization, which also agrees to remove it at the user's request. This equipment contains no facilities for user testing, maintenance, or adjustment; there are no user-serviceable components inside.
In case of difficulty, the user should consult a representative of the manufacturing organization with any questions or problems. Direct inquiries to the following location:
