SS7 OVERVIEW
SS7 Overview
• TDM Telecom landscape littered with protocols
– ISDN, CAS, R2, V5.2, GR-303, … and SS7
• SS7 = Signalling System Number 7
• Deployed in Carriers / Service Providers Networks
• Roots of specifications date back to the 70s
– To counter blue box fraud
• Incumbent Telcos massively deployed in late 80s
• It is the basis for LNP, CNAM, 800/freephone
numbers, GSM wireless networks
• Networks moving to VoIP but there are still a lot
of SS7 networks out there

SS7 Protocol Stack
• SS7 allows for call to be established, monitored,
torn-down, etc.
• Network Nodes are identified with Point Codes
– it is like an IP address for SS7 networks
• SS7 protocol has several layers
– MTP 1, 2, 3 for routing SS7 messages
– ISUP for call set-up and tear-down
– TCAP for database transactions
(800, CNAM, LNP, Mobile)

• TCAP is not a required function for
VoIP Gateways

1 Channel is reserved to
carry the SS7 Protocol
messages for all the T1/E1
in the trunk group
All other channels
carry voice in
TDM format (in

called CIC =
Carrier Interface
Channel, each CIC
has a number)

SS7 VoIP Gateway Explained
• They are required to interconnect legacy PSTN
networks to next generation VoIP Networks
• Hence VoIP Gateways are translators
– They convert TDM Protocols to IP Based Protocols
and vice-versa
– They convert TDM voice to IP based voice and
vice-versa

SANGOMA’S
NETBORDER SS7 GATEWAY
Sangoma’s Involvement in SS7
• Sangoma has offered SS7 solutions to various
degrees over the years
• Started with our own SS7 ISUP stack
– Back then we competed with Open Source
– Our solutions were ‘piece parts’ of boards and pieces
of software – clunky assembly required
– It got our feet wet, developed expertise and allowed
us to continually raise the bar
• We now have NetBorder SS7 Gateway, a full
fledged GW, that integrates a carrier grade
Trillium SS7 stack. The product comes ready to
configure and put in service at the customer site

Current NetBorder SS7 Gateway
features
• Up to 32 E1 per server
• SS7 ISUP Signaling with several national variants
– ITU, ANSI, Bellcore, France, UK, China, India and Russia
• SIP VoIP Signalling
• Wide range of narrowband and wideband codecs
supported
– for any to any codec transcoding
• Flexible XML based routing rules for call control
• For reference, we use a Trillium SS7 stack
– Commercial and carrier grade
– Facilitates conformance testing with various carriers

New Features with NSG Ver 5.0
• Key Features:
Megaco = Media
Gateway Control
Protocol
– SNMP monitoring for T1/E1
– Radius Protocol for Management
– H.323 (legacy VoIP interconnects)
– SIGTRAN M2UA – called Signalling GW or SG
– MEGACO / H.248 signalling – called Media
Gateway or MG
These are the big deal features, next few slides explain why

In this scenario, NSG is a
slave to the softswitch.
Large service providers
want this because it
simplifies their network
deployments. Central
billing, central monitoring,
can install GW everywhere
with the same basic
configurations.

Go After the Bigger Fish
• SS7 to SIP is OK for small networks
– Small Service provider
– Value Added Services
• SIP is too limiting for networks with large
amount of interconnection POPs
– Megaco and M2UA allow for
better distribution of network
– Facilitates integration with large
softswitch vendors that
service providers use

Conformance Testing
• Incumbent Telco often impose lab certification
before a competitive service provider is
allowed to interconnect
• It is not a requirement for vendors, it is a
requirement for Service Providers – our
customers

COMPETITION
Open Source SS7

•
•
•
LibSS7 (Digium) / Chan_ss7
Unstable and difficult to work with
Poor variant coverage and certification record
Most serious carriers are not interested in using
an open source stack and making their own
gateways
• Only a factor in emerging markets where price is
the only decision factor. Sangoma does not
compete in such situations where the buyer only
wants the cheapest/free solution.

Squire Technologies
• UK based, founded approx in 2002, About 25
people, £ 5M run rate annually
• All solutions built from Audiocodes Boards and
APIs – expensive and can only hope to offer the
same features as Audiocodes
• Extensive SS7 solutions (not just gateways)
• Poor channel coverage
• Very present at Service Providers shows
• Actively promoting as replacement to Cisco EOL
products – Cisco PGW and Cisco IPT

Cisco SS7 EOL products
• Cisco PGW:
– it is a softswitch
– Can be configured as a VoIP GW but it does a lot more
– Can recommend our NSG but we are not feature
comparable – only if the PGW is used as a GW, then
we are good
• Cisco ITP:
– It is mostly a Signalling Transfer Point (STP) and a
Signalling Gateway
– With NSG release 5.0, we can replace a Cisco ITP if it is
used as a signalling gateway (we cannot be an STP)

CLOSING
Summary
• The NetBorder SS7 Gateway is a cost effective
and robust solution delivered in a compact 1U
or 2U appliance.
• It offers a good protocol coverage and feature
set at the best price per port of the
commercial market.
• This product is perfectly suited for the carrier
market in emerging markets where CAPEX
budgets are tight.
