Abbreviated Dialing. Enter the Abbreviated Dialing number digits While system This may be for users do not have direct access to outside lines from their phones; These procedures are just as simple to perform as basic call handling. The hold system allows you to deal with situations like this. A caller can remain connected to the console, connected to you leaving To retrieve a call from Hold Press the chosen HOLD key with the red lamp steadily lit The red lamp goes out and the held caller returns to the console.
The access codes are programmable. If, for instance, you have a caller wants to speak to Janet Young, If absolutely necessary, can override intrude into this conversation and talk to the extension user. To use the Paging System Press and hold Attendant Functions To Enter an Abbreviated Dialing The system has deleted the number from its memory. This feature particular application in Hotels Motels. A blocked extension only dial unblocked extensions, the operator, or external numbers.
You cannot change the list of blocked extensions, but you can turn the feature Dial 0 to clear the meter and have it start numbering again from zero. Outside calls that normally ring at console then ring at an alternate answering point. The alternate destination could be an extension, a hunt group, ring group Or you may need to be away from the console for a short time. Overflow lets deal with both these situations by temporarily diverting all calls See Attendant Function Codes in Chapter following types printout When system is first started, the date always Maintenance personnel might ask you for this information.
Since the procedure disconnects callers on the trunk, it should used with caution. It does not release a busied-out trunk.
If the call is not answered, the system tries again twice, at five minute intervals. Fill in these lists so that you will have the information when you need it. As this software level is backward compatible with all previous TSX50 systems. The SX50 is an Integrated Communications System using an innovative, compact modular design which allows easy system expansion, fault finding and card replacement. SX50 is a digital electronic system, using stored program control and advanced digital architecture.
SX50 can be adapted by data changes to match a wide range of public exchanges. Although cost-effective as a basic telephony switch, the SX50 has been designed as an integrated voice and data switch.
This means that it can be adapted to handle future communications applications including voice, data, text and image.
Main Components The main components of an SX50 system are as follows Cables connecting the power supply unit to the wall socket, between the equipment cabinet and the console, and connecting the Extension and Trunk Cards to the Test Jack Frame. Installation The Backplate for the SX50 equipment cabinet is fixed to a wall. The Card frame is attached to the Backplate. The Motherboard is inserted, followed by the power supply unit which is clipped to the side of the frame. Finally the Generic Module is clipped to the right hand side of the frame and connected to the Motherboard.
The printed circuit cards can now be inserted. After this the cables are installed from the equipment cabinet to the mains socket and to the Exchange Lines and extensions, via the Test Jack Frame. The cable to the console can be connected through the Test Jack Frame or directly to the Control Card. Telephones SX50 can be used with loop disconnect dial, MF4 keypad and self contained Decadic keypad telephones in any combination. Customer Data Entry After installation, the installation engineer powers up the system and carries out customer data entry from the console.
This data defines the various features required by the customer and matches the system to the local Exchange Lines. The configuration of an SX50 system can be altered by redefining some of the data. The customer is allowed to change some of the data if required. A security code prevents unauthorised access to the system. Traffic Considerations The digital switching matrix in the SX50 is totally non-blocking for the maximum configuration of 32 Exchange Lines or extensions.
Maintenance Every five years the small lithium battery in the Generic Module must be replaced. Apart from that, no routine maintenance is required or recommended. Diagnostics and Fault Correction The SX50 uses comprehensive automatic diagnostic procedures which run continuously and indicate, on the console, any faults that may be detected. In general, if a non urgent fault is detected, the system isolates and busies out the faulty circuit and continues operation though possibly with reduced performance.
Detailed diagnosis of faults can be carried out at the console. Site work is limited to changing specific plug-in modules or boards and the modular design makes this quick and simple.
Background diagnostics can also be run on demand. Emergency Switching If SX50 suffers a power failure, the system automatically goes over to Emergency Switching Mode, in which up to 10 Exchange Lines can be mechanically switched to selected extensions. These extensions are then powered from the local exchange, enabling some external communication from the system. When power is restored, normal operation resumes.
Customer data is held during power failure by the Lithium battery in the Generic Module. Environmental Characteristics Briefly, SX50 requires an office environment which remains within the limits:. SX50 is resistant to electro-magnetic interference expected in ordinary conditions and does not emit electro-magnetic radiation likely to affect most users. There is no fan and acoustic noise is well below accepted limits.
The SX50 Cabinet must be wall mounted. It is an enclosed circuit board containing the system memory and a Lithium battery which protects the memory from loss of data for up to 10, hours if the mains power supply fails.
The W unit provides extra capability by allowing a larger system configuration to be used. The Power Supply Unit is clipped to the left side of the Card frame and can be readily removed. The W Power Supply Unit requires approximately 1 amp at volts and provides a continuous output of Watts.
Both Power Supply Units are protected by fuses. The Control Card carries The Peripheral Cards all plug into the Control Card, perpendicular to the wall, so that their front edges are exposed. It is possible to withdraw the Peripheral Cards sufficiently to allow the Control Card to be removed and replaced, without having to remove the front connectors on the Peripheral Cards.
