NOTE
• Copper ground lug (P1) must beconnected
to a known approved ground location.
Ensure metal to metal contact on all
connections and verify ground circuit
continuity.
• TheRJ48connectorcanbewiredfor2,4,or
6-wiretechnologies. Anyexcesswireshould
be clipped.
The label inside the housing (see Figure 2) depicts
various technologies that can be accommodated
These technologies include DDS, HDSL, HDSL2,
Fractional T1, ADTRAN’s Total Reach ISDN, and
Total Reach DDS
Power
The T400 Housing is designed for both a
loop-powered or locally-powered circuit card The
terminal strip provides for connecting an external -48
Vdc supply to the circuit card These connections are
made to the -48V and -48VR on TS1 Connections
from the terminal strips to the edge connector are
described in Table 2
