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 6220T-TSG-DD and 6220U-TSG-DD are on-hook secure versions of the 6220 ISDN Telephone. These models meet the requirements for TSG-6 certification set by the National Telecommunications Security Working Group. All appropriate electronic circuitry has been modified to ensure the 6220-TSG models meet TSG-6 on-hook security measures.
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.
