The H2TU-C-319 List 7 line unit is the Central Office (CO) side of a T1 transmission
system. The H2TU-C, when used with an H2TU-R remote unit, transmits a
1.544 Mbps payload on one unconditioned copper pair over the full Carrier Service
Area (CSA) range. The H2TU-C-319 List 7 is designed to mount in 3192
mechanics shelves.

EQUENCE
When the H2TU-C powers up, the four-character display illuminates and displays
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:
•
The Status LED flashes red while acquiring the H2TU-R and then turns a steady
green when the entire system is operating with no alarms. (The DS1 signal must
be present.)
•
The front-panel display reports signal-to-noise ratio (SNR) margin readings
(should be
≥
6 dB) and loop attenuation (should be < 28 dB).
After the system powers up, existing alarm conditions are reported on the display.
(The H2TU-C reports alarms if no DS1 signal is applied.)

ROVISIONING
Perform these basic provisioning tasks:
1 Connect a maintenance terminal to the craft port (see front-panel illustration
inside) and log on. (If logging on through the management unit, the default
password is public.) Press
+ to refresh the logon screen, if necessary.
Refer to the onscreen Help menu for navigational aids or use the (to
cycle through selections), (to activate the current setting or selection, or
to display a menu), or
(
to return to the parent menu), or directional
arrow keys (to navigate to a menu or item).
2 Select Config, Date and Time, then type the date and time.
3 Select Inventory, then type the circuit ID, H2TU-R ID and circuit notes.
4 Change the settings of any system parameters, if necessary, by selecting Config,
then Standard Options or ADC Options. (Configuration options can also be set
from the front panel using the MODE and SEL pushbuttons. See
Table 2 inside.)
Once the H2TU-C is successfully installed and provisioned, access the Monitor,
Performance, or Event Log menus to clear the Performance, Alarm History, or Event
Log screens, or use Master Clear in the Config menu.
