Chapter 1. About the NT1 Type 400
POWERING TEs FROM THE NT1
The ADTRAN NT1 Type 400 can be used to provide power for cus-
tomer TEs. If the NT1 T400 circuit pack is used, a total of 12 watts is
available. If the NT1 Type 400 Standalone unit is used, a total of seven
watts is available. This power can be provided by Power Source 1
(PS1), which provides power over the transmit and receive wire pairs
used by the S/T interface and requires no additional wire pairs; and
by Power Source 2 (PS2), which provides power over an additional
wire pair.

The NT1 Type 400 Standalone rear panel contains three RJ45 connec-
tors, as illustrated in Figure 1-1. A single connector, labeled NET-
WORK, is used to connect to the ISDN network. The remaining two
connectors, labeled CUSTOMER 1 and CUSTOMER 2, are used to in-
terface to the customer's TEs. These connectors are wired in parallel,
and can be used to connect multiple TEs in a passive bus arrangement.
