We provided the customer with a committed testing
team for extended periods to help maintain the
installations.
This included equivalence testing, regression
for previous releases of the switch and standardization
testing, as well as proving compliance to benchmarks
set by large network operators. Protocols included
SS7 (ISUP and TCAP), BRI/PRI (Q.931), X.25, X.75
and proprietary standards defining interconnection
between remote switching units.
Our team of 12 engineers has tested the product
over seven software releases in the last three
years to the satisfaction of the customer. This
has allowed the customer to greatly reduce product
defects before reaching the field.
The customer benefits greatly with each passing
year as the team maturity increases, thus revealing
increasing number of product defects before reaching
the field.
