THE SITUATION
Long distance calling rates between North
America and Europe to Africa, Asia, and
Latin America are very expensive. As a
result, a large and lucrative business
has sprung up providing discounted calling
cards using Internet-based PSTN toll by-pass
solutions. However, the next-generation
networking equipment used to enable the
Internet-based solutions cannot connect
to the local telephone networks in Africa,
Asia, and Latin America. The signaling
used in these regions is incompatible with
the softswitches and VoIP gateways manufactured
for the North American and European markets.
THE CHALLENGE
Emergent and incumbent
carriers are looking for a cost effective
way to connect their softswitches and
VoIP gateways into an international exchange
for calls to countries based on R2 and
C7 signaling. They also want to scale
up their networks as the demand for services
increases. And, they want to untie expensive
Class 5 switches from the role of protocol
conversion and allow the ports to be
deployed for higher-revenue generating
customer services.
THE SOLUTION
Encore Networks provides
the pivotal equipment needed to enable
the deployment of softswitches and gateways
in Africa, Asia, and Latin America. Encore’s
SignalPath™ 201 and 230 products are
proven to connect internationally with
a variety of softswitch and VoIP gateway
vendors, and can be scaled to meet the
varying sizes of in-country deployments.
Encores’ SignalPath™ 201 and 230 platforms
provide scalable solutions for bridging
the gap between the North American and
European ISDN and SS7 softswitch and
VoIP gateway interfaces connecting to
foreign PSTN networks based on variants
of R2 and C7. Encore’s SignalPath™ line
of products seamlessly integrates with
products from today’s leading softswitch
vendors, such as Santera, Metaswitch,
Taqua, and Quintum, as well as VoIP gateway
products, such as Lucent’s MAX TNT and
Cisco’s 5300/5400.
The SP201 converts up to four trunks
of ISDN to four trunks of SS7 for handling
call volumes of up to 92 simultaneous
non-blocking sessions. The SP230 scales
from four to 44 trunks, handling call
volumes of up to 1,012 simultaneous non-blocking
voice sessions. These devices provide
a huge operational savings over a central
offi ce-based solution.
Encore Networks supports global signaling
variants for both North American and
international variants of ISDN and SS7,
including R2, C7, R1, ANSI NI 2, and
ETSI (Euro) ISDN
