Siemens LTUCX Q2166 for Hicom 300

Description

The line trunk unit control extended (LTUCX) board has twice the number of speech highways as in the former LTUCE board. It is supported for a standard LTU shelf by adding new 2x4x2 MB highways to the already existing 2x4x2 megabit highways. As an LTU shelf is devided into two shelf halfs, each shelf half supports 128TSL of bundle A and 128TSL of bundle F.

The additional speech highways can only be used by boards which support this feature (for example the DIU-N2 and DIU-N4 boards). Within the board configuration it is determined if the board uses the standard speech highways or the additional ones. Simultaneous use of all highways is not supported with this feature.

You can now use a few new boards (to access additional highways; reservation of many TSLs for every board; for example, DIU-N4 = 128 TSL) with a greater number of old boards (only access to the standard highways; reservation of few TSLs per board) together in the same shelf in a non blocking configuration.
