The LL2100 is a selectable baud-rate in multiples of 64 or 19.2 KILOBAUD X.21 optical interface unit which is designed to extend a CCITT V11 data and control signal to be communicated between DTE and DCE or DTE and DTE equipment over fibre. The unit is especially designed for SYNC operation at 64 or 19.2 kBaud. The data rate extends to 2048 and 614,4 kBaud. The unit is housed in a small metal enclosure.SPECIAL FEATURES
The unit is modular in design and thus can be upgraded with different optics or power supplies. The distance over which the system can operate is determined by the fibre interface used. The options are limited to 3.5, 12, 16, 36, 50 and 70 Kilometres. The power supply module is removable and can be interchanged with either 220 VAC, 110 VAC or 48 VDC units. Other voltages can be supplied on request. The unit is compact and can fit two aside on a ?19? rack? shelf with a height of 1U. The system uses the latest technology in line driving integrated circuits and is therefore complies fully with the stringent CCITT standards. Baud rate is selectable between multiples of 64 and 19,2 kBaud up to 2048 kBaud.
