Data Connection Announces Portable SS7 Software
February 4, 1999
LONDON--(BUSINESS WIRE)Data Connection Limited
(DCL), the world's leading vendor of portable
ATM and SNA communications products,
today announced that it is extending its
highly successful product suite to include
support for carrier class Signalling System 7
(SS7).
The new DC-SS7 product family provides the
OEM market with a flexible source code
solution suitable for use in a full range of
telecom devices from traditional switches
(SSPs), signal transfer points (STPs) and
service control points (SCPs), to more recent
developments such as IP telephony gateways
(VoIP) and the infrastructure for 3rd
generation wireless networks (IMT-2000 and
UMTS). The DC-SS7 product suite runs within
Data Connection's existing portable,
non-blocking, message passing execution
environment. This, combined with an
advanced fault tolerant architecture, provides
the performance, scalability and reliability
required for the most demanding of today's
SS7 applications.
"Today's carriers and enterprises require
99.9999% availability and are looking to
increase both throughput and function of
their networks" said Colin Dancer, Director of
Data Connection's Telecoms Business Unit.
"This requires SS7 software which supports
fast signalling links, both broadband and
narrowband traffic and which can be adapted
to a range of uses. The DC-SS7 architecture
has included these features from day one,
along with fault tolerance, redundancy and
portability. By utilizing our products and
expertise, equipment vendors can reduce
development cost and time to market, while
being confident of meeting their customers'
most stringent quality and reliability
requirements. They also get the benefit of
our continuing product development and an
easy upgrade path to new features."
The initial members of the DC-SS7 product
family implement the Message Transfer Part,
ISDN User Part, Transaction services and Call
Control for both narrowband and broadband
SS7 networks. Support is provided for a wide
range of national and international variants
including those defined by the ITU, ANSI,
ETSI and ATM Forum. Products will become
available during the course of 1999.
The full list of family members and their
functions is as follows.
- DC-ISUP (ISDN User Part)
Supports the protocol to setup, maintain and
drop narrowband
calls across an SS7 network.
- DC-BISUP (Broadband ISDN User Part)
Supports the protocol to setup, maintain and
drop broadband calls
across an SS7/ATM network.
- DC-MTP3 (Message Transfer Part - Level 3)
Provides the traffic, link and route
management for narrow and
broadband signalling networks.
- DC-SAAL (ATM signalling adaptation layer)
Implements reliable data transfer over ATM
signalling links.
- DC-SCCP (Signalling Connection Control
Part)
Provides end-to-end routing and global title
translation.
- DC-TCAP (Transaction Capabilites
Application Part)
Provides access to remote network entities
such as databases and
management applications. TCAP is an integral
part of the
"Intelligent Network" concept.
- Call Control including interworking between
ISDN, ISUP, B-ISUP,
ATM UNI and ATM PNNI is provided by
DC-Gateway, DCL's generic
gateway product.
DC-SS7 integrates seamlessly with DCL's
Asynchronous Transfer Mode (DC-ATM) and
VoIP/Gateway (DC-Gateway) products, and
uses the same proven communications
framework. This framework has been ported
to a large number of operating systems
including VxWorks, pSOS, Chorus, Nucleus,
Solaris, HP-UX and Windows NT, and has
been used on all common processors including
x86, i960, Motorola 860, Sparc, IDT and
MIPS. Proprietary OSs and chipsets can be
supported with minimal effort.
