- Page 2 APPROVALS ___________________________________________________________________________ This product conforms to the requirements of EMC DIRECTIVE 89/336/EEC Emissions StandardsEN 50081-1 Immunity StandardsEN 50082-1 ___________________________________________________________________________ BABT APPROVAL REQUIREMENTS FOR THE UNITED KINGDOM This device incorporates a Dataflex Design ISDN Basic Rate Module which has been approved by the British Approvals Board for Telecommunication (BABT) for connection to the Integrated Services Digital Network (ISDN).
- Page 3 GENERAL INFORMATION The GSGC4 and GSGC5 units are very similar. The GSGC4 being a cut down version of the GSGC5 primarily for use by a reporter, while the GSGC5 has more channels and would normally be used where more than 1 person is contributing . Both units are designed to make it very easy to send a programme to an ISDN line.
- Page 4 INSTALLATION INFORMATION ISDN INSTALLATION To install this equipment refer to drawing A2-12812. It is only necessary to:- Plug in the ISDN cable (RJ45) from the mixer to the BT ISDN point. Plug in the Mains PSU (if required) from the rear of the mixer to a standard 13amp mains socket.
- Page 5 OPERATING INSTRUCTIONS POWER This equipment is usually powered from its own internal D Cells. These must be alkaline cells, such as 'DURACELL DB2' This equipment can also be powered from an external DC supply. There is a 3 position switch on the rear panel marked 'EXT-OFF-BATT' .
- Page 6 LAST NUMBER REDIAL A momentary press of the "REDIAL" button will redial the last number dialed. This button is inoperative if the ISDN light is on. That is if a call is already in progress. If the unit is switched off the last number dialed will be forgotten. MEMORY REDIAL It is possible to save up to 12 frequently used numbers in non volatile memory.
- Page 7 SOFTWARE CONFIGURATIONS Several functions in this equipment can be set to meet your exact needs. These setups are held in non volatile RAM and will be remembered until changed. These functions are all set by turning the box off by the 'EXT-OFF-BATT switch on the rear panel and then turning it back on while holding a particular combination of buttons.
- Page 8 4) CHANNELS TO BE FORCED OFF WHEN A CONNECTION IS MADE :- Factory default forces no channels off. When a connection is made, regardless of if the box is manually answered, auto answered or originates a successful call, it is possible to ensure that any channels can be forced off despite their current state.
- Page 9 7) SET DTMF RINGER MODE :- Factory Default is sounder on. When a call has been established an incoming DTMF tone can be made to operate the front panel sounder. Switch on while holding "HANG-UP" & "6". "POWER" LED lights immediately to confirm set-up operation. Release "HANG-UP"...
- Page 10 11) SET SUB-ADDRESS MODE:- Factory Default will not affect the sub-address. It is possible to allocate a sub address to the box. If the network presents a sub address and the box has a sub address set, the box will only ring if these sub addresses match. Switch on while holding "ANSWER"...
- Page 11 HARDWARE CONFIGURATIONS HEADPHONES This equipment is usually supplied with 'split ear' headphone connections. That is cue programme is wired to only the left ear and mixer output is wired only to the right ear. This will produce sensible results with either mono or stereo headphones. Provision has been made however to mix either or both sources into either or both ears.
- Page 12 MPEG NOTES If the unit is fitted with our MPEG layer II codec some extra facilities become available. MODE OF OPERATION Our MPEG codec will try to establish lock with the codec at the other end of the ISDN line. It will attempt communication in MPEG at 16, 24, 32 or 48KHz sampling as well as G722.
