Lucent Technologies
Link Layer connectivity for Argentina's cell phone system
In 1993, when Lucent Technologies installed
a cellular telephone system in Argentina,
they chose an analog system because the
newer digital technology was too costly.
They needed a communications link to connect
the analog cell site equipment to the
telephone switch in the central office.
Gcom® was the only company to provide
a solution, offering customized LAPB and
LAPD protocol for the control of telephone
circuits.
The project was an unprecedented success
not only for Gcom, but also for Lucent,
which was able to deploy the entire system
in only 60 days. Despite the extremely
fast rollout time, the cellular phone
network has proven stable from the outset,
largely due to the reliability of the
Gcom protocols used to manage the network
infrastructure. In fact, the success of
this project led to the selection of Lucent
to deploy Argentina's next-generation
digital cellular network. |
