Network and customer loopbacks are governed
by the loopback time out option (defaulted to
120 minutes).

Control Port Terminal Access
The H2TU-R provides a front panel mounted DB-9
connector that supplies an RS-232 interface for
connection to a controlling terminal. The pinout of the
DB-9 is illustrated in Figure 4

Figure 4. RS-232 (DB-9) Pin Assignments
The terminal interface operates at data rates from
1.2 kbps to 19.2 kbps. The asynchronous data format is
fixed at 8 data bits, no parity, and 1 stop bit. The
supported terminal type is dumb terminal, VT100 or
compatible. The line wrap feature of emulation
programs should also be disabled.
NOTE
If you are using a personal computer with
terminal emulation capability, be sure to
d i s a b l e a n y p o w e r s a v i n g p r o g r a m s .
Otherwise, communication between the PC
and the HDSL2 unit may be disrupted,
resulting in misplaced characters or screen
timeouts.
A terminal session is initiated by entering multiple
spacebar characters, which are used by the H2TU-R to
determine the speed of the terminal. Once the speed has
been determined, an HDSL2 Main Menu is presented,
which will be detailed in the
HDSL2 section.

5. PROVISIONING

Through management access via the front panel DB-9
connector, the provisioning settings can be viewed and
manipulated, as detailed in the
HDSL2 section.
Table 7 lists the available provisioning options and the
factory default settings.
