POWERING MODES
This T200 H2TU-R is locally powered only. If a span powered H2TU-R is required,
order P/N 1223026L2.
RS-232 DB-9 CONNECTOR
Used to access performance monitoring data, perform loopbacks, and provision units
via VT100 emulation applications, such as HyperTerminal - Private Edition.
♦
There are two types of terminal emulation modes:
♦
Manual Emulation Mode
: Press the spacebar three times to manually update the
screen. Print screen and log file commands are available in this mode.
♦
Real-Time Emulation Mode
: The default mode. Print screen and log file
commands are not available in this mode. Cursor placement and screen
highlighting are enabled.
Use
C
TRL
+T
to toggle between the two terminal emulation modes.
♦
Provision terminal port for VT100 as follows:
♦
Data Rate:
1.2 to 19.2 kbps
♦
Asynchronous Data Format:
Eight data bits, no parity (none), one stop bit
♦
When using a PC with terminal software, disable any power saving programs.
PUSHBUTTON LOOPBACK FUNCTIONS
♦
LOC
-
Initiates a bidirectional loopback of the H2TU-R toward the network and
customer
♦
REM
-
Initiates a bidirectional loopback at the H2TU-C toward the network and
customer
DS1 BRIDGING (BANTAM) JACKS
If the DS1 test set is optioned for
MONITOR
, the monitor jacks provide a nonintrusive
tap onto the signal line.
♦
TX
-
Monitors the data stream being received from the customer equipment
♦
RX
-
Monitors the data stream being transmitted to the customer equipment
