Introduction
This manual provides information covering installation and set-up procedures of the G-
Converter Channel Card, types G-Converter Nx64 and G-Converter Nx64 (M)
These cards are designed to be used in conjunction with a G-Converter Chassis System for
which there is a separate manual.
G-Converter Nx64 (M) Channel Cards are interface adapters that will convert between a
G.703/G.704 link and an X.21/V.11 interface or optionally V.35.
The intended use of these units is to terminate G.703/704 links. These units have the ability
to operate at DCE rates between zero and 2048Kbps in 64k steps. Selection of these DCE
rates is conveyed across the G.703/G.704 link from the central site management unit by a
proprietary in-band-signalling scheme.
Two variants of the G-Converter Nx64 Channel Cards are available: G-Converter Nx64 and
G-Converter Nx64 (M).
G-Converter Nx64
The G-Converter Nx64 is configured and managed via the Manager Card housed in the G-
Converter Chassis .The G-Converter Nx64 Channel Card has a tri-coloured LED mounted on
the front panel, this indicates the card status, additional information is available from the
Management System.
G-Converter Nx64 (M)
The G-Converter Nx64 (M) incorporates two rotary switches accessible through the front
panel. In addition to the tri-coloured LED there is also a dual seven-segment LED display on
the front panel. peration of the rotary switches permits the G-Converter Nx64 (M) Channel
Cards to be operated without a Manager Card. If preferred the G-Converter Nx64 (M) may
be managed by the Manager Card, this is achieved by selection of onboard DIL switches.
Functional Overview
G-Converter Channel Cards provide interface and rate conversion between G.703 data stream
and X.21/V.11 or optionally V.35 interface.
The E1 connection is via either an RJ45 connector offering a120- hm balanced impedance
or two BNC connectors offering an unbalanced 75- hm impedance. The N x
64Kbps,X.21/V.11 connection is via a 15 way D type connector. V.35 connection is also
available on a 15 way D type connector, a conversion cable providing MRAC connection is
available as an option.

Typical applications
Typically the G-Converters are used to connect a router with an X.21/V.11 or V.35 interface
to an E1 circuit with G.703 interface. Additionally both versions offer the ability to reduce
the data rate of the X.21 or V.11/V.35 interfaced connection in 64Kbps steps.

Configuration and Use - G-Converter Nx64
There are no switches or configuration links on the G-Converter Nx64 Channel Card. All
the management and configuration is performed through the G-Converter Chassis Manager
Card. This allows the G-Converter Nx64 Channel Card to be configured either by SNMP,
data terminal (VT100) via the supervisor port or Telnet.
Use of these management media are covered in the G-Converter Chassis user manual and
repeated below.
This manual will cover the specific configuration and management of the G-Converter Nx64
Channel Card.

This RS232 option is presented on a female 9 Way-D connector. It can support VT52,
VT100, ADDSVP, ADM3A, H1500, N8009, and TVI920 terminal emulation modes.
Selection of the required option is made on the power up screen.
Supervisor Terminal Requirements
The terminal should be configured as follows:
8 bits per character, no parity, one stop bit, speed 19.2 Kbps.
A ‘modem’ or ‘straight’ serial cable is suitable for connection of the Supervisor port (the
Supervisor port pin-out out is described in Appendix C).
Supervisor Terminal Emulation
The Manager Card supports several terminal emulations. When connection is made between the
terminal and the RS232 Supervisor port, the following screen will appear:
The terminal type or emulation in use should be selected by pressing the relevant number key on
the PC or terminal. The terminal will then show the basic configuration screen for the chassis’s
set-up.
You may return to this screen at any time by pressing ‘CTRL’ and ‘E’ at the same time.

0 Base-T Port (Telnet Management)
This method uses the 10 Base-T RJ45 (Ethernet) port. When a Telnet compatible PC is
connected to this port a management platform identical to that available via the Supervisor
Port is supported.
Before Telnet or SNMP management is used, it is essential that the notes relating to
Supervisor Port Management be studied. (See pages13-16).
To enable SNMP or Telnet management, information must be added to the Manager Card via
the Supervisor Port. The user must first set up various parameters namely IP address, Subnet
Mask and Gateway.
The information required is:
System Name
A text field to identify the system. May be up to 32 characters.
Location
A text field to identify the location of the system. May be up to 32 characters.
IP Address
The IP address of the system. This must be set from the supervisor port to enable SNMP or
Telnet access.
Subnet Mask
The Subnet mask of the local network. This must be set from the supervisor port before
SNMP and Telnet access is required.
Gateway
The IP address of the default gateway from the local network.
To assist the process of adding this information, the relating to Supervisor port management
is detailed below.
