The modems provide synchronous communications at user data rates between 64kbps and
2048kbps over a single fibre. The equipment has modular user interfaces, which allows the
equipment to be configured to meet many different installation requirements. Both rack and
desktop versions of all units are available. Desktop units are AM2048A and rack mount units
are AM2048B. This manual covers the desktop units.
The AM2048A OS provides full duplex transmission at 2.048Mbps over a single single-mode
optical fibre.
The AM2048A OM provides full duplex transmission at 2.048Mbps over a single multi-mode
optical fibre.
Separate interface modules can also be purchased in order to modify the units for operation
with a different terminal interface at a later date.
The AM2048 can easily be configured via a VT100 dumb terminal. It is recommended to use a
VT100 terminal emulation program running on a notebook or palmtop PC (see FAQs for
details about obtaining a VT100 emulator program). Using the menu system with on-line help
should reduce the need to refer to the handbook. The VT100 Management User Guide gives a
full description of the menu system.
Once configured, the operation of the AM2048 is totally automatic. In the event of line
disturbances or power failure, the data link is restored without operator intervention.
Chapter 4 (Installation) describes the basic set up procedure and this should be read prior to
setting up any link.
Modifications to line cords and power supply leads are available for country specific
requirements. In such cases, the line cord pin-out may be different.
