Dealing with PSTN migration
As an incumbent service provider in an increasingly
saturated fixed voice market, you face the declining
profitability of your PSTN. With severe competition,
the average price per minute of voice calls is decreasing;
moreover, cable operators are offering attractive service
bundles; alternative VoIP providers are offering low tariffs
using third-party access networks, and some customers are
abandoning fixed voice lines in favor of mobile phones.
At the same time, your operational costs are flat at best,
with a trend to increase as the TDM network becomes
older and obsolete. In fact, the eventual cost of running
the network will no longer be justified by the revenue
the network generates.
To meet these challenges, you are looking to migrate your
PSTN to an IP network. Remaining competitive means
optimizing the delivery of traditional voice services while
creating an all-IP network capable of delivering new voice
and multimedia services. This dual-pronged strategy makes
sense. As broadband penetration continues to grow, you
can combine your investment in the modernization of the
PSTN with the building out of IPTV and high-speed
Internet access networks — two areas currently undergoing
substantial growth. Adopting an IP- and Ethernet-based
platform with the flexibility of bringing fiber as close as
economically possible to the end user, will also let you
achieve your goal of converged voice and data access
networks, with minimum cost of ownership.
As part of their strategic initiative,
service providers should re-evaluate
current service offerings and product
lifecycles, and prioritize services to
be migrated onto next-generation
network architecture. It’s not efficient
to migrate all services to the next-
generation network at the same
time — service providers should take
a step-by-step approach for network
optimization. Network optimization
should be based on increasing network
capacity and improving operational
efficiency.
