ADC HIGAIN H2TU-R-402 LIST 7G Original operating instructions

THE H2TU-R-402 LIST 7G/LIST 7H
The H2TU-R-402 List 7G/List 7H (H2TU-R) functions as the remote end of a
repeaterless T1 transmission system when connected toa HiGain®, Wideband System
3190, or Soneplex®HDSL2 line unit (H2TU-C). The H2TU-R-402 List 7G is line
powered and the H2TU-R-402 List 7H is locally powered. Setting new standards for
interoperability and efficiency, HiGain HDSL2 modules transmit 1.544 Mbps T1
payload on one unconditioned copper pair over the full Carrier Service Area (CSA)
range.

VERIFICATION
Once installed, verify that the H2TU-R is operating properly by monitoring the Status
LEDs on the front panel.
LOGGING ON TO THE MAIN MENU
The H2TU-R supports local and remote logon through a maintenance terminal (ASCII
terminal or a PC running terminal emulation software) connected to the craft port on the
H2TU-R front panel.
Logging on creates menus and screens for the H2TU-R that are replicationsof those viewed
at the H2TU-C. Once logged on, you can view system settings and inventory, initiate
loopbacks, monitor performance, and configure the circuit.
To log on using a maintenance terminal:
1Press + to refresh the Logon screen, if necessary.
2Press the first letter of the desired menu. Use the to cycle through menu
selections, and press to change a setting or to display a menu.
LOOPBACK TESTING
Initiate loopback testing from the maintenance menus, H2TU-R front-panel pushbutton,
H2TU-C front-panel pushbuttons, or with inband codes sent by a test set (see table below).
For more information about loopback testing, refer to the H2TU-C line unit user manual.

Craft port provisioning
To access all system maintenance, provisioning,
and performance screens, connect a standard
9-pin terminal cable between the serial port on a
PC and the H2TU-R craft port.
Loopback control pushbuttons
Press the pushbutton for 5 seconds to activate a dual loopback
at the network (RLB) or at the customer (LLB).
The unit can be looped down by pressing either
control pushbutton again for 5 seconds, by the standard
loopdown inband messages, or by the maintenance terminal.
Any existing loopback is terminated before these loopbacks
are activated.

Use to remove the
H2TU-R-402 from

VERIFICATION
Once installed, verify that the H2TU-R is operating properly by monitoring the Status
LEDs on the front panel.
LOGGING ON TO THE MAIN MENU
The H2TU-R supports local and remote logon through a maintenance terminal (ASCII
terminal or a PC running terminal emulation software) connected to the craft port on the
H2TU-R front panel.
Logging on creates menus and screens for the H2TU-R that are replicationsof those viewed
at the H2TU-C. Once logged on, you can view system settings and inventory, initiate
loopbacks, monitor performance, and configure the circuit.
To log on using a maintenance terminal:
1Press + to refresh the Logon screen, if necessary.
2Press the first letter of the desired menu. Use the to cycle through menu
selections, and press to change a setting or to display a menu.
LOOPBACK TESTING
Initiate loopback testing from the maintenance menus, H2TU-R front-panel pushbutton,
H2TU-C front-panel pushbuttons, or with inband codes sent by a test set (see table below).
For more information about loopback testing, refer to the H2TU-C line unit user manual.
