Cermetek telephone line interface modules provide a complete telephone interface within a single component. They can be used for a variety of communication applications including, modems, DTMF signaling and voice.
Cermetek offers telephone line interface modules with a wide range of features. Most Cermetek telephone line interface products are FCC compliant but do not include FCC Part 68 Registration. The CH1840 and XE0068DT models provide the billing delay, transmit level control, and lightening protection required for FCC Part 68 Registration.
Like Cermetek modem products, the FCC Registration on these units is transferable to Cermetek customers.
