The card is ideally suited for the fax program CapiFax S2M and for the voice mailbox CapiCall S2M. A special crossbar logic significantly reduces echo effects in speech applications. The card can be combined with a 1/2/4 S0 card if required.

Pinout of the S2M cable
The S2M line of Telecoms do not always have the same pinout. Some have an RJ45 port, others are for direct wiring. The table on the right shows two common layouts. Note that this is typically not the same as for a standard S0/T0 port! The colours are the ones of the supplied Primux cable. When looking on the blank contacts of the RJ45 plug and the cable is at the bottom, Pin 1 is leftmost and Pin 8 is rightmost.
