The EGSC is a GSC unit integrated with an embedded PC. The PC is packaged in the GSC enclosure into a single unit: it is connected to the GSC board via an internal communications cable and to an external power supply.

The EGSC offers station installation, which includes a PC, in an enclosure that is installed in the ceiling, eliminating the need for a desktop PC. This solution is suitable for stations where it is unfeasible or uneconomical to install a PC.

The EGSC is externally identical to a standard GSC.
