General Features _____________________________________________
Tone Commander 6220-TSG-DD ISDN Telephones are easy to use multiline terminals with advanced
automatic setup capabilities. These models have been TSG-6 certified by the National Telecommunications
Security Working Group (NTSWG) to ensure on-hook security measures. In addition, the speakerphone
circuitry has been removed and all automatic call origination and answering functions have been disabled.
The phones do not provide voice encryption on an active call.
S/T and U interface models are available with 20 call appearances. An external NT1 Network Termination,
such as the Tone Commander NT1B-300TC, is required for S/T models. The phones support Lucent 5ESS
Custom ISDN and National ISDN on a variety of network platforms (see page 44).

Models/Options ______________________________________________
Two telephone models are available; they differ in the type of ISDN connection.
Models are identified on
the bar code/serial number label on the bottom of the phone.
The
6220T-TSG-DD
model requires an external NT1 Network Termination, such as the Tone Commander
NT1B-300TC. Two S/T telephones can share a single ISDN line in a multi-point arrangement.
The
6220U-TSG-DD
model includes a built-in NT1, allowing direct connection to the ISDN line without an
external NT1.
Options include the
6030X Button Expansion Module
, which adds 30 multifunction keys, and the
6002TA
Analog Port Terminal Adapter
for interfacing with an analog telephone device, such as an STU-III
telephone.
Both models are supplied with the
TSG-DD1 Disconnect Device
, which completely disconnects the ISDN
line from the phone when power is not applied, and a
-PWR1 Desktop Power Supply
.
