Page 7: Introduction
Standalone G-Converter Introduction This manual provides information covering installation and set-up procedures of the converter. A full set of cable pin-outs and a PCB layout (showing the location of switches and link settings) are included in the appendices. The G-Converter is an interface adapter that will convert between a G.703/G.704 link and an X.21/V.11 or V.35 interface. -
Page 8: Operating Modes
Standalone G-Converter Operating Modes The equipment has four operating modes: Refer to the Switch and link location diagram in Appendix D -Location Of Switches and Links. Operating Mode 1 G.703 Transparent interface converter, data rate fixed at 2048kbps, Remove the cover of the unit, locate Internal Switch 4 and set as follows: SW4,1 SW4,2 SW4,3... -
Page 9: Operating Mode 3
Standalone G-Converter 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 N.B. NR = Not Relevant. 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. -
Page 10: Interface Presentation
Standalone G-Converter G.703 Interface Presentation The converter may be configured to operate on either a 120 ohm balanced circuit impedance, presented on an RJ45 connector or with a 75 ohm unbalanced impedance, presented on two BNC connectors. Selection of the interface is made by link settings – refer to Appendix D -Location Of Switches and Links for the location diagram and use in conjunction with the tables below. -
Page 11: Selection And Configuration Of Dce Interface
Standalone G-Converter Selection and Configuration Of DCE Interface The DCE port of the G-Converter can be presented as either X.21/V.11 or V.35 Choice of interface is made by link setting. The X.21/V.11 interface is presented on a 15-way D type connector in accordance with ISO 4903. -
Page 12: Configuration Of V.35 Control Flags
Standalone G-Converter The G-Converters support one input flag and two output flags. It is up to the user which of the signals is to be implemented. RTS would normally be the definition for Flag 1 I/P (although is does not have to be) as this is the only I/P called up by the V.35 spec. The two output flags, Flag 2 O/P and Flag 3 O/P can be assigned to either CTS, DSR or DCD, the choice is at the discretion of the user. -
Page 13: Remote Loopback Function
Standalone G-Converter Remote Loopback Function If the stand-alone G-Converter has SW5, 1 to off, the Manager card located in the card cage may select a remote loopback. Once this state has been entered, it will remain in loopback for approximately 3 minutes. Whilst in loop back, the LED display will flash “rL”, the data and clock being outputted through the DCE port will be suppressed and the data arriving at the X.21/V.35 drivers/receivers will be looped back to the central site. -
Page 14: External Clock
Standalone G-Converter External Clock The G-Converters have the ability to use as its clock source a clock supplied from the connected DTE. An external clock is supplied externally to the converter via the EXT clock pins, of the 15 way D type connector (pins 7 and 14). Whenever an external clock is used, the rightmost decimal point of the seven-segment display is illuminated. -
Page 15: Configuration
Standalone G-Converter Configuration Configuration of the G-Converters is achieved in two simple stages involving internal and external switches, and setting of some internal links. Refer to Appendix D -Location Of Switches and Links for details of Internal Switch and link locations. Selection of internal links permit the converters to operate either as a Local or Remote unit. -
Page 16: Dil Switch Settings
Standalone G-Converter DIL switch settings The mode of operation is set up using the DIL switches SW4 and SW5. SW POSITION FUNCTION SETTING SW4, 1 Selects either remote Off = local operation or local operation On = remote SW4, 2 Selects interface type Off = G.703 On = G.704... -
Page 17: Default Unit Set-Up
Standalone G-Converter Notes: Only allow unframed operation if a DCE speed of 2048Kbps will not “harm” the DTE. Use this mode if no in-band management is required and the link is required to run a permanent 2048Kbps. Also, use this mode if interfacing to another manufacturers G.703/X.21 interface converter. -

Page 19: Diagnostics
Standalone G-Converter Diagnostics Front Panel LEDs On the front panel, only the CARRIER LED and POWER should normally be illuminated. When the G-Converter is disconnected from the network or has lost carrier the CARRIER LED will extinguish. Seven Segment Display The seven segment LED display can reveal the state of the G-Converter. - Page 20 Standalone G-Converter A BERT tester configured, as a DTE capable of generating test patterns should be connected to the “DCE” port of the G-Converter. With the link interface disconnected, the LOOP switch on the energised G-Converter set to Local, the BERT tester will detect the clock being generated by the G-Converter and if the unit is operating correctly the looped back data should be error free.

Page 21: Installation
Standalone G-Converter Installation Before installation, please refer to the safety warnings, approvals requirements and EMC requirements in the appendices. Supply Voltage and Connection 240V AC. The Converter is AC powered by a “plug in” switched mode power supply that is provided with the unit. -
Page 22: Back-To-Back Demonstration Connection
Standalone G-Converter Back-To-Back Demonstration Connection For a simple demonstration, or local network use, two converters may be connected ‘back to back’, using a cross over cable arrangement, one unit will automatically adopt the role of clock master the other clock slave. 75 ohms BNC to PD7024 interfaces For UK interfaces a pair of 75 Ohm BNC cables should be used, connecting TX on one unit to RX on the other and visa versa. -
Page 23: Appendix A - Warnings
Standalone G-Converter Appendix A - Warnings WARNING: THIS EQUIPMENT MUST BE EARTHED/ GROUNDED VIA THE SCREEN OF THE X.21 DTE LEAD This equipment relies on the EARTH/GROUND connection to ensure EMC compliance.
