THE H2TU-C-319 LIST 6
The H2TU-C-319 is the Central Office (CO) side of a repeaterless T1 transmission
system. The system provides 1.544 Mbps transmission on one unconditioned copper pair
over the full Carrier Service Area (CSA) range. Enhanced firmware also allows the
H2TU-C-319 to be deployed in Soneplex
®
Wideband 3190 protection switching
applications. These applications must meet the following requirements: HiGain
multiplexers (HXU-358s) using software version 1.04 or higher, an HMU-319 List 7A or
List 7C using software version 3.06 or higher, an HRE-206 remote enclosure equipped
with a PSC-606 List 1 protection switching controller, and an H2TU-R-402 List 6 remote
unit.

INSTALLATION
Align the H2TU-C-319 with the enclosure slot guides, then slide the unit in until it
touches the backplane card-edge connector. Push the H2TU-C into the slot guides
until properly seated in the card-edge connector.
POWER-UP SEQUENCE
When the H2TU-C powers up, the four-character display illuminates and reports
status messages.
If the H2TU-C is unable to communicate with the H2TU-R, it displays various alarm
and status messages. If the H2TU-C is able to communicate with the H2TU-R, the
following occurs:
1The Status LED flashes red while acquiring each device in the system, and turns
a steady green when the entire system is operating without any alarms. (The DS1
signal must be present.)
2The four-character display reports margin (SNR) readings (shouldbe ≥6 dB) and
loop attenuation (should be <35 dB @196 KHz).
3After the system powers up, any alarm conditions that exist are reported on the
display. (The H2TU-C reports alarms if no DS1 signal is applied.)
PROVISIONING
After installing the H2TU-C-319, perform these basic provisioning tasks by accessing
the logon screen. Refer to the onscreen Help menu for navigational aids or use the
(to cycle through selections), (to activate the current setting,
choice, or to display a menu), or (to return to the parent menu), or
directional arrow keys (to navigate to a menu or item).
1Connect a maintenance terminal to the craft port (see front-panel illustration
inside), then press + to refresh the logon screen, if necessary.
2Select the Config menu, Date and Time, then type the date and time.
3Select the Inventory menu, then type in the unit ID numbers.
4Change the settings of any system parameters, if necessary, by selecting the
Config menu, Standard Options or ADC Options. (Configuration options can
also be set from the front panel using the MODE and SEL pushbuttons. See the
“Front-Panel Configuration Options Using MODE and SEL”table inside.)
5Once the H2TU-C-319 is successfully installed and provisioned, access the
Monitor or Performance menus to clear the Performance, Alarm History, or
Event Log screens, or use Master Clear in the Config menu.

Four-character display
Displays status, provisioning, and
alarm messages. See tables below
for a list of message descriptions.
Reports the following conditions:
Use MODE and SEL to manually modify user options,
initiate loopbacks, and display DSX-1 line parameters.
Connect standard test equipment.
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-C craft port.
1Press the MODE pushbutton for 1 second and release.
The front panel alternately displays the first system
parameter and its current setting.
2Press SEL to step through all possible settings for
the displayed parameter.
3Press MODE to update the parameter and advance
to the next parameter.
4After scrolling through all the parameters, press SEL
to confirm changes when prompted with a CONF NO
message, or press MODE to cancel all changes.

THE H2TU-C-319 LIST 6
The H2TU-C-319 is the Central Office (CO) side of a repeaterless T1 transmission
system. The system provides 1.544 Mbps transmission on one unconditioned copper pair
over the full Carrier Service Area (CSA) range. Enhanced firmware also allows the
H2TU-C-319 to be deployed in Soneplex
®
Wideband 3190 protection switching
applications. These applications must meet the following requirements: HiGain
multiplexers (HXU-358s) using software version 1.04 or higher, an HMU-319 List 7A or
List 7C using software version 3.06 or higher, an HRE-206 remote enclosure equipped
with a PSC-606 List 1 protection switching controller, and an H2TU-R-402 List 6 remote
unit.

INSTALLATION
Align the H2TU-C-319 with the enclosure slot guides, then slide the unit in until it
touches the backplane card-edge connector. Push the H2TU-C into the slot guides
until properly seated in the card-edge connector.
POWER-UP SEQUENCE
When the H2TU-C powers up, the four-character display illuminates and reports
status messages.
If the H2TU-C is unable to communicate with the H2TU-R, it displays various alarm
and status messages. If the H2TU-C is able to communicate with the H2TU-R, the
following occurs:
1The Status LED flashes red while acquiring each device in the system, and turns
a steady green when the entire system is operating without any alarms. (The DS1
signal must be present.)
2The four-character display reports margin (SNR) readings (shouldbe ≥6 dB) and
loop attenuation (should be <35 dB @196 KHz).
3After the system powers up, any alarm conditions that exist are reported on the
display. (The H2TU-C reports alarms if no DS1 signal is applied.)
PROVISIONING
After installing the H2TU-C-319, perform these basic provisioning tasks by accessing
the logon screen. Refer to the onscreen Help menu for navigational aids or use the
(to cycle through selections), (to activate the current setting,
choice, or to display a menu), or (to return to the parent menu), or
directional arrow keys (to navigate to a menu or item).
1Connect a maintenance terminal to the craft port (see front-panel illustration
inside), then press + to refresh the logon screen, if necessary.
2Select the Config menu, Date and Time, then type the date and time.
3Select the Inventory menu, then type in the unit ID numbers.
4Change the settings of any system parameters, if necessary, by selecting the
Config menu, Standard Options or ADC Options. (Configuration options can
also be set from the front panel using the MODE and SEL pushbuttons. See the
“Front-Panel Configuration Options Using MODE and SEL”table inside.)
5Once the H2TU-C-319 is successfully installed and provisioned, access the
Monitor or Performance menus to clear the Performance, Alarm History, or
Event Log screens, or use Master Clear in the Config menu.
