Teo NT1B-300TC-TSG - Manual

The Tone Commander
NT1B-300TC-TSG converts
an ANSI standard 2B1Q
ISDN U-interface from the
telco Central Office to an
S/T interface to connect to
local customer terminal
equipment. Both
point-to-point and multipoint
ISDN terminal equipment
configurations are
supported.
The NT1B-300TC-TSG is
intended for use in
standalone applications
with TSG-6 approved S/T
interface ISDN terminals,
such as the L3
Communication Systems
STE, or the Tone
Commander 6220T-TSG,
where the NT1 is collocated
within the SCIF area.
This model complies with ANSI T1.601-1992 and T1.605-1991
interface standards, including MLT (Mechanized Loop Testing)
requirements, and is compatible with National-1 and National-2
ISDN standards. The NT1B-300TC-TSG is a modified version
of the Tone Commander NT1B-300TC, with special hardware
modifications to support TSG security requirements.
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.
