1.Be sure the power jumper is set to the LINE position.
2.Connect a ground wire to either the Power terminal plug (Post 4) or to the frame ground stud on the
rear of the CSU. (Do not use both at once) This is the only connection needed for the Line Power
Option.

The 
Tl Digital Trunk Card kit contains a power transformer to convert AC power to the 48 volt DC
power supply required for the CSU. Using 20 gauge leads or larger, wire power to the six-post terminal
plug and install the plug in to the rear panel. Connect Pin 
l- Battery Return (V+) and Pin 3- Battery (v-)
to the transformer.

4.CONNECTING THE CSU TO THE Tl CIRCUIT
When the options have been set and the TI type and Line fype have been programmed for each Tl channel, slidethe stand-alone card into the card guides of the mounting shell. Secure the card in position with the screws
provided. Connect the system to the Tl circuit.
1.Connect the CSU to the Network interface through the NETWORK connecto$ (P2). Plug the 15pin
connector on the cable provided into the P2 connector on the CSU board. Plug the 8-pin RJ-48X Connector
on the other end of this cable to connect to the 
Tl line.L
2.Connect the CSU to the infinite DVX illDigital System using the Equipment connector (J4) on the rear of
the CSU.
If all connections have been made, and the 
Tl trunk is active, check the front panel of the Tl trunk card. The Test
Mode LED should flash at a one second rate. The Receive Carrier Loss LCD (DS2) should be off.

Line BuiI&Out Options
Set the Line Build-out switches to compensate for loss between the last repeater and the CSU. The five-position
switch on the front of the CSU selects Line Build Out (LBO) Separate 
LBOs set the transmit levels for the Network
and CPE sides of the CSU. Receivers on both sides of the CSU contain Automatic Line Build Out circuitry to
compensate for loss of signal (LOS) from the network. Set the Line Build-out switches using the following tables:

Step 2. Comection to the Network and Customer Premise Equ@ment (CPE)
Two RJ48 modular connectors are located on the bottom of the CSU.First connect modular connector labeled
“NET” to the Network using the Network cable. Then connect the 
“CPE” from the CSU to the Tl in the
DVX

Step 3. Powerhg Options
The ADTRAN CSU kit contains an external power adaptor. Always use this adaptor in all ipstallations.The power
connection is located on the bottom of the CSU.
