Product Details

Model GLS-12 is designed to allow up to 12 standard telephone sets, multi-line key systems or other loop start equipment to be connected to and operate on two-wire ground start CO trunk lines. The GLS-12 provides the CO ground start line with the signalling required to draw dial tone when the loop start equipment goes off-hook. Incoming calls are not affected by the GLS-12 and ring directly to the loop start devices.


Applications

  • Allows PABX and key systems configured for loop start trunks, as well as standard telephones to be connected to C.O. ground start trunks
