ST-TC1 Telco Line Simulator

The ST-TC1 is a device that simulates a telephone company (telco) line for connection to a telephone switching unit (KSU). The ST-TC1 becomes the provider of an inbound line to your switch, so when any of your instruments pick up the line provided by the ST-TC1, a contact closure is provided and bi-directional audio is available through the module. In this manner, audio can be routed through the telephone coupler to or from the telephone equipment. This connection can be used to add paging zones to a phone switch, or control communications radios. Because the ST-TC1 simulates a phone line, it can also connect directly to a telephone instrument for constructing private intercom systems.
