Descriptions
Primary multiplexer МХЕ1-11 is designed for multiplexing channels from various analog and digital interfaces into standard stream E1for transmission to higher level multiplexers. The type and number of such channels is determined by a set of the expansion cards. The multiplexer supports the work of 11 expansion cards. The multiplexer is installed at the terminating point and is designed to work as a part of the equipment OVG-21.
Scopes
- Multiplexing of VF, RS-232/485, FXS, FXO channels;
- Easy addition and replacement of expansion cards;
- Synchronization selecting and tracking;
- Monitoring the operation of all unit interfaces;
- PC control and diagnostics;
- Easy maintenance.
