PUSHBUTTON LOOPBACK FUNCTIONS (LBK)
♦
LOC : Initiates bidirectional loopback of HTU-R toward the network and customer
♦
: Initiates loopback at the HTU-C toward the customer
REM
DS1 MONITORING (BANTAM) JACK (MON)
The front panel of the HTU-R contains a metallic bantam jack for DS1 test access.
Monitor
If the DS1 test set is optioned for MONITORING, the monitor jack provides a non-
intrusive tap onto the signal line.
♦
: Monitors the data stream being transmitted to the network from the customer
TX
♦
: Monitors the data stream that would be received from the network to the customer

Yellow DS1 provisioned for B8ZS line coding
Off Unit not in loopback or armed state
Green Active remote loopback from the HTU-C toward the cus-
tomer and/or network
2

124x004L6).
4. Span Power is an option that is only valid for the HTU-C and will not display on the HTU-
R user interface.
OPTION JUMPER
P3 sets the DS1 NIU 60 mA Current Setting as follows:
♦
Off disables the constant current source for the DS1 NIU.
♦
On Enables the 60 mA constant current source for the DS1 NIU.
INSTALLATION AND TURN-UP
After unpacking the unit, inspect it for damage. If damage is noted, file a claim with the
carrier and then contact ADTRAN. Refer to Warranty.
NOTE: This unit can be provisioned via the RS-232 port or remotely via inband codes.
1. Set the option jumper according to the specific circuit design.
2. Install the HTU-C and HTU-R.
