Data Sheet NSA-PL Line card for SOS Line interconnection in 6 wire technique Functional description: Voice transmission between the call station and DVS-21 is carried out as SOS Line with additional transmission of control and monitoring signals and power feed in 6wire technology. The audio channel is shared with all SOS Line users. Each NSA-PL line is secured both by a PTC and a fuse on the front panel.

Data Sheet NSA-PL Line card for SOS Line interconnection in 6 wire technique In SOS Line (PL) Application, the overall number of call station depends on the characteristic of the transmission medium, the spacing between the call stations and the operation mode. Typical values are as follows: No. of WPS-PL (Active / Idle) 8 (1 / 7) 15 (1 / 14) 26 (1 / 25) 26 (1 / 25) Spacing [m] 500 500 500 500 Wire diameter [mm] 0.9 0.9 0.9 1.2 No. Of wires 3x2 4x2 3x4 4x2 Max.
