Restoring test defaults
76 T-BERD/MTS 5800 Getting Started Manual
Restoring test defaults
You can restore test settings to the factory defaults at any
time.
To restore test defaults
– On the Main screen, select Tools > Reset Test to
Defaults.
The default settings are restored for the currently running test
(or the currently selected one if multiple tests are running).
VT-100 emulation
If your instrument is optioned to do so, you can use it to
emulate a VT-100 terminal, and then connect it to a network
element (such as an HTU-R, HTU-C, HRE, or SmartJack
(NIU)) via a serial interface to gather information about the
element. When emulating a VT-100 terminal, data from the
network element appears on the T-BERD ⁄ MTS 5800 screen.
You can save this information to an ASCII file, print it, or
export it. Information gathered typically includes loss, margin,
synchronization, performance (SES, ES, UAS, etc.), and
alarm information.
During a VT100 session, you can also configure and provision
the accessed network element from the T-BERD ⁄ MTS 5800.
When using VT-100 emulation, you must connect the optional
USB keyboard to the instrument to issue queries and
commands.
Establishing a
serial
connection
When you order the VT-100 Emulation option, JDSU ships a
RJ-45 cable with the instrument or option. This cable has
been tested for use with the T-BERD ⁄ MTS 5800, and should
be used whenever you connect the T-BERD ⁄ MTS 5800 to a
network element for VT-100 communication. An RJ-45 to DB9
adapter is also required.
