Standalone G-Converter
TECHNICAL: 0118 931 2233
Operating Mode 3
G.703 Interface, data rate configurable between 0bps and 1984kbps
Remove the cover of the unit, locate Internal Switch 4 and set as follows:
SW4,1 SW4,2 SW4,3 SW4,4 SW4,5 SW4,6 SW4,7 SW4,8

When converters are to be set up as a pair, one unit MUST be configured as a Local unit
(SW4, 1 = Off) and the other a Remote unit (SW4, 1=On)
The external Loop switch (front panel) should be set as Normal.
In this mode, data rates may be selected between 0bps and 1984kbps in 64kbps steps. A
proprietary framing scheme is used to control the value of N.
Use this mode if you are sure you will not want to use N = 32 (i.e. 2048kbps).
When operating in this mode, a fault condition on the G.703 link will force the DCE clock to
operate at 0kbps and display “Er” on the display.
Operating Mode 4
G.704 Interface, data rate configurable between 0bps and 1984kbps
Remove the cover of the unit, locate Internal Switch 4 and set as follows:
SW4,1 SW4,2 SW4,3 SW4,4 SW4,5 SW4,6 SW4,7 SW4,8

When converters are to be set up as a pair, one unit MUST be configured as a Local unit
(SW4, 1 = Off) and the other a Remote unit (SW4, 1=On)
The external Loop switch (front panel) should be set as Normal.
In this mode, all speeds are possible between 0bps and 1984kbps in 64kbps steps. A
proprietary framing scheme is used to control the value of N.
Operating Mode 4 would be used if you were connected to a G.704 network. In this mode, a
fault condition on the G.704 link could force the DCE clock to operate at 0kbps and flash
“Er” on the display.
