With universal compatibility and "best in class" performance, every Teo ISDN phone provides easy installation, automatic setup, and user friendly operation. Just select the interface type, style, and number of buttons that best meets your needs for both commercial and government applications.
Teo also manufactures a complete line of NT1 ISDN Network Terminations for connecting digital voice and data equipment to the ISDN network. NT1 models include desktop, wall mount, and open card versions, with several powering options. Racks and battery backup are available for multiline configurations.
From the ergonomically designed handset to simplified labeling, the 8600 Series shows a thoughtful evolution from our industry-standard 6200 Series. Automatic set-up capabilities and simple programming make the phones quick to install and easy to use. Reliable and never obsolete, new feature enhancements and upgrades can be added easily.
The NT1B-300TC is a compact ISDN Network Termination suitable for standalone or rack configurations. Terminal equipment (typically ISDN telephones) can be powered through the NT1. Power is provided by an in-line desktop power supply or by the rack.
The NT1B-300TC-TSG is a specially designed version of the Teo NT1B-300TC compact ISDN Network Termination. This model has been certified by the National Telecommunications Security Working Group (NTSWG) for use in standalone applications with TSG-6 approved S/T interface ISDN terminals, such as the L-3 Communication Systems STE, or the Teo TSG-6 ISDN Phone 6220T-TSG, where the NT1 is collocated within the SCIF (Sensitive Compartmented Information Facility) area.
