Page 4: General Information
GENERAL INFORMATION GSGC6 This unit is a 1U subrack designed to provide ISDN facilities in a studio, it contains a terminal adapter, a mains power supply, some control electronics and space for 1 or 2 codec type cards. The terminal. adapter is a 'Dataflex' IM90 module. This is a twin unit capable of dealing with both B channels of an ISDN 2 circuit at the same time. - Page 7 GSGC6 INSTALLATION GENERAL The GSGC6 is a 1U subrack designed to be fitted in an equipment rack or apparatus room. Although there are some indicators and 3 controls on the front panel, it is not necessary to access these. MAINS An IEC mains connector with a retaining clip is provided on the rear panel.

- Page 12 GSGC6 Command Language The AT Command Set A Hayes type AT command/response interface is used to communicate with the GSGC6 internal Terminal adapter. Data sent to the TA are treated as commands and data received from the TA are treated as responses (eg result codes). All command lines must begin with the characters AT and must be entered in a single case.
- Page 13 AT / AD Command Set Attention This is the prefix for all AT commands. Typing AT by itself (followed by a carriage return) will result in the "OK" message being displayed and no other action being performed. It is good practice to use this command to check that your terminal software is communicating correctly.
- Page 14 Hang Up This command can be used to "hang up" the Terminal Adaptor. Identify Parameters: Returns information about the Terminal Adaptor. Quiet (Message Control) Default: Switches result messages on or off. ATQ0 Result messages will be displayed. ATQ1 Result messages will not be displayed. Set or Read S Registers Parameters: r=n,r?

AT&W Save TA Configuration in NV-RAM This command will save the current configuration of the Terminal Adaptor. AT&Z Store Telephone Number Parameters: x=nnnnnnnnnn This command is used to store a telephone number into the Terminal Adaptor's directory.

Page 18: Result Codes
RESULT CODES When a command is issued, the GSGC6 responds with a result code (either OK or ERROR) to indicate whether it understands and can act on the instructions. Result Codes also report the progress of a connection.

These are the identities of local terminal and also information contained in both incoming and outgoing messages to the network. S100 Terminal primary adddress Default: None...
- Page 21 S104 Incoming called party number This will contain the Number of the called party for the last call received. This will only be so if the network passed the information across with the incoming call. This will be present when multiple subscriber numbering (MSN) is being used. S105 Incoming called party sub-address This will contain the Sub-address of the called party for the last call received.
- Page 22 S120 Call termination cause This register will contain the cause value as presented by or to the national network when a call is cleared. Common Causes: 3 - no route to destination 16 - normal call clearing 17 - user busy 18 - no user responding 19 - no answer from user 21 - call rejected...
- Page 23 S122 Primary B channel incoming This allows the user to select the channel or channels for which an incoming call will be presented. This will be the first element of an incoming call that will be checked . If the check fails the call will be ignored otherwise the call will be passed to the nest filtering section.

Page 25: Installation Information
INSTALLATION INFORMATION GENERAL This unit is designed to control our GSGC6 ISDN 1U subracks. It consists of a small plastic case with and LCD display and keypad. In addition 4 other switches and 2 LEDS are provided. It is usual to have one GSGC7 controller for each codec fitted in the GSGC6 subrack, then the circuits can be used entirely independently. - Page 27 GSGC7 OPERATING INSTRUCTIONS GENERAL This unit has a standard keypad and 4 additional buttons. It also has a 2 line by 16 character LCD display. The display is used to prompt the user and to show various actions. KEYPAD Each of the 0 to 9 keys has 3 or 2 letters of the alphabet printed next to them. In some uses of these keys it is possible to use them to enter a particular letter.
- Page 28 TO ANSWER AN INCOMING CALL It is possible (see engineering set-ups) to set this equipment to automatically answer an incoming call. If this has been done no action is required by the operator. If set for manual answer simply press the 'DIAL' button to answer the call. CALLING NUMBER IDENTIFICATION (CLI) If your ISDN circuit has CLI enabled on it, the display will indicate the calling party.
- Page 29 TO MODIFY SET-UP DURING A CALL These facilities are codec dependent. Not all options are meaningful with all codecs. If an unavailable selection is made, the equipment will try to revert to an available mode. When a call has been successfully connected and the RED LED is on, it is possible to force the codec parameters.

Page 30: Engineering Set Ups
ENGINEERING SET UPS The GSGC7 can be used to programme the set ups in the GSGC6 1U subrack. In general the 'Grey' (MENU) key is used to proceed to the next stage. First press the 'Grey' key. At this stage anybody can set the viewing angle of the display. When a suitable viewing angle has been set enter it by pressing the 'Grey' key. -
Page 31: Display Message
