   UT620U                Single NT1 - Discontinued - replaced by NT3 and NT4.

The UT620U terminates and converts the two-wire U-Interface that comes from the telephone company to a four-wired S/T-Interface to provide ISDN telephones, Video Conferencing Systems or other ISDN CPE devices access to BRI ISDN services.

The NT1 comes with just a single power supply option - i.e. the universal full range 9.8W IEC Switching Power Supply (SP62040) (110-240V, 50/60Hz), with appropriate IEC cord.

The UT620U used to be offered with 2 different power options depending on your need to power your CPE (Customer Premise Equipment).  The 2W Power Supply (AM9200) provides power to the UT620U only and is ideal for video conferencing applications. The universal full range 9.8W IEC Switching Power Supply (SP62040) (110-240V, 50/60Hz), with appropriate IEC cord, provides not only power to the UT620U, but also provides ITU Standard Power Source 2 (PS2) power through the S/T-Interface to the ISDN CPE and is ideal for ISDN telephone applications.
The UT620U conforms to industry standard 2B1Q line code for the U-Interface; ANSI T1.601-1992.  The S/T-Interface conforms to ANSI T1.605-1991; ITU/CCITT I.430 standards; and is a FCC, DOC, ETL/CETL approved device.  Its reliable design protects against lightning and power surges.
