| NT1B-300TC-TSG ISDN Network Termination for Secure Areas | |
|
The
NT1B-300TC-TSG
is a specially designed version of the Tone Commander
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 Tone Commander 6220T-TSG, where the NT1 is collocated within the
SCIF (Sensitive Compartmented Information Facility) or SAPF (Special Access
Program Facility) area.
Complete metallic disconnection of the U interface on the ISDN Line jack is provided when the NT1 is not powered, and the design ensures that unintentional microphonic audio signals are not detectable on external wiring. Only two pins (4 and 5) are used on the U Line modular connector; all other contacts have no connection. Both point-to-point and multipoint ISDN terminal equipment configurations are supported. A local power supply is
included. CNSS Number: CNSS-A-02-2009 Made in USA |
