Status Description
Off No sync between the HTU-C and HTU-R on Loop 1/Loop 2
Green Signal quality is good (4 to 9)
Yellow Signal quality is marginal (1 to 3)
Red Signal quality is poor (0)
Flashing Error at HTU-C or HTU-R; Loop signal quality indicated by
color of flashing LED
Off DSX signal is not detected or is of a format that does not
match the provisioning of the HDSL circuit
Green DSX signal is present and synchronized with the HTU-C's
interface
Flashing Bipolar violation (BPV), frame bit error (SF mode) or CRC
error (ESF mode) detected on received DSX signal
Off No alarm conditions exist
Yellow Remote alarm condition (HTU-R) detected
Red Alarm condition detected either locally (HTU-C) or locally
and remotely (HTU-C and HTU-R)
Off Unit is receiving unframed
Green Unit is currently receiving SF data
Yellow Unit is currently receiving ESF data
Green Unit is receiving AMI line code
Yellow Unit is receiving B8ZS line code
Off Unit is not armed or in loopback
Yellow Unit is in loopback toward the network.

Used to access performance monitoring data, perform loopbacks, and provision units
via VT100 emulation applications, such as HyperTerminal–Private Edition. There are
two terminal emulation modes: Manual Update and Real-Time Update.

screen. Print screen and log files commands are available in this mode.
♦
Real-Time Mode: The default mode. Print screen and log file commands not
available. Cursor placement and screen highlighting are enabled.
Terminal Port
Provision the terminal port for VT100 as follows:
♦
Data Rate = 9.6 kbps, 19.2 kbps
♦
Asynchronous Data Format = eight data bits; no parity (none); one stop bit.
When using a PC with terminal emulation software, be sure to disable any power
saving programs.

COMPLIANCE
Refer to the 3192 HTU-C Compliance Notice (P/N 61247004L1-17)
for detailed compliance information.
INSTALLATION
After unpacking the unit, inspect it for damage. If damage is noted, file a claim with
the carrier and then contact ADTRAN. For more information, refer to the warranty.
