Siemens S5-135U/155U appendix Standard Connect- ing Cables of the V.24 Submodule

CPUs, Memory Cards, Memory Submodules, Interface Submodules

With jumper J6, you can set all V.24 receivers so that you only require positive-going signals (positive voltage region).

J6		All received signals must be at
		V.24 signal level.
		All received signals can be in the
		positive voltage region.

With the submodule 0AA23, bridge 6 has no function; all signals can lie in the positive range (corresponds to bridge setting 2-3).

With jumper J9, CTS can be set permanently to quiescent potential, i.e. switched through from the front connector.
