Overview
The GS-1 Loop Start to Ground Start Converter allows equipment designed for connection to standard loop start telephone circuits to operate with ground start telephone
circuits.
Two versions are available. The GS-1-8 provides eight circuits of loop start to ground start conversion. The GS-1-12 provides 12 circuits of loop start to ground start conversion.
Both units require no external power source for operation they are powered by the ground start trunks. Installation is easy; simply connect the GS-1 between the loop start equipment and the ground start trunks.
Both units are completely self-contained in a wall-mounted cabinet. Interconnections are made using a 25-pair plug. The GS-1 is FCC registered and UL
LISTED.
