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. This viewing angle is
not yet stored for future use but will remain fixed until the equipment is switched off.
After setting the viewing angle you will be asked for a password before any engineering set ups
can be altered. After entering the correct password you will be led through the available set
ups. These are as follows:-
AUTO ANSWER2-9 Specifies number of rings to answer by.
0 = Manual Answer
OUTGOING B CHANNELCan be B1, B2 or either
INCOMING B CHANNELCan be B1, B2 or either
MULTIPLE SUB NO.This should be all digits including the area code
SUB ADDRESSUp to 4 alphanumeric characters
NEW EXT SWITCH NUMBERThis is the ISDN number that will be
automatically dialled when the DC loop is closed
on the rear panel of the GSGC6
ENCODE MODEForces the Encoder mode
SAMPLE RATEForces the Encoder sample rate
DATA RATEMake call at 56/64 KBits/Sec data rate
DTMF DURATIONSpecified in hundredths of a second duration of
each DTMF digit.
DTMF DC-LOOPSpecifies DTMF code sent when DC loop made
on rear panel of GSGC6
DTMF DETECTSets the DTMF code required to close the relay
loop on the rear panel of the GSGC6 and to
operate the GSGC7 sounder and lamps
if enabled
DTMF KEY PADEnables the GSGC7 key pad to send the DTMF
code corresponding to the key pressed.
DTMF LAMPMakes the ISDN lamp flash on valid DTMF
DTMF SOUNDERMakes the sounder operate on valid DTMF
ISDN SOUNDERMakes the sounder operate with incoming call
After the above parameters have been set they must be stored in the NVR (Non Volatile Ram).
This is achieved by pressing the 'Green' key when asked. If the 'Red' key is pressed the above
set-ups are aborted. This action of pressing the 'Green' key also stores the view angle that was
entered before the password.
The set up is independent for each port on the GSGC6. If 2 codecs are fitted to the GSGC6 it is
essential to repeat the set up using the second port.
It is possible to reset the microprocessor in the GSGC7. A reset switch has been fitted adjacent
to the 15pin D connector. This can be accessed by sliding off the plastic cover marked 'OPEN'
on the rear of the unit.
