| > Features and Benefits |
|
 We
have paid special attention to the optical connectivity by including most
connectors and wavelengths. Thanks to its dual transmitter, any combination
of 1550 and 1310nm is available in one instrument.
-
Functions, the Macros enable automatic, measurements with the press
of a button. The Autoconfiguration detects signal structure. Fastscan explores
the alarms and errors in the synchronous tributaries.
-
Touch&Play ©, the simple syntax and the touch screen offer
you the most natural and efficient user interface on the market.
-
A rugged hand-held, Victoria is fitted with a rubber boot
to provide the best protection possible. Its small size and light weight
makes Victoria a handy instrument, especially suited for field and factory
work.
-
SoftLEDs ©, with 10 tricolor LEDs identified on screen, up
to 100 events can be displayed simultaneously.

| > Applications |
|
| Powerful and easy to handle, Victoria is the ideal tool
for work in both exchange and central office environments, and also out
in the field.
Testing Network Elements
Before they are connected, multiplexers must pass mux/demux tributary
tests and M/N stress tests that activate the generation of errors and alarms.
Their behaviour when faced with offsets, G.783 pointer sequences and a
change in the reference clock must also be studied.
Stressing ADM multiplexers by means of frequency offset
Victoria can generate frequency offset on the tributary side in order
to check pointer adjustment mechanisms on multiplexers.
Commissioning
Next, the network elements and transmission media are connected together
to form the topology of the transmission network.. This is done by means
of a series of tests, such as BER test in VCs, RTD, transparency tests
for all RSOH, MSOH, POH bytes and trail trace in J0, J1 and J2.
Service Level Agreement (SLA)
Operators must guarantee their customers a certain level of quality
for the services they offer, both in terms of performance (G.821, G.826,
M.2100 and M.2101) and unavailable time when faced with a breakdown that
provokes APS.
Internetworking
Applications that make use of several networks in tandemare becoming
common. When a breakdown occurs or there is a deterioration in quality,
the cause must be identified using TCM
Preventive maintenance
Centres with groups of experts perform long-term ISM measurements.
With Victoria they will have specialized screens, graphs and traces at
their disposal showing all the alarms, errors and pointer movements that
occur.
Synchronization Network
The Victoria frequency deviation function allows to stress clocking
systems to quickly identify deficiencies in the synchronization network.
Most of the problems during maintenance are due to lack of synchronization.
