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 SS7 parlance 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

Similarities with Enterprise Gateways

• VoIP Gateways are translators– Take legacy PSTN protocols– Convert them to VoIP

• Enterprise Gateways convert End-User to Network protocols– Analog, BRI, PRI

• Carrier Gateways convert Carrier to Carrier protocols– Such as SS7

SANGOMA’SNETBORDER 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


• 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

Current NetBorder SS7 Gateway features


New Features with NSG Ver 5.0

• Key Features:

– 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

Megaco = Media Gateway Control Protocol

SS7 to SIP Gateway (local network intelligence)

1. SS7 traffic arrives at NSG2. TDM Voice arrives at NSG3. SS7 Stack decodes protocol up to ISUP layer4. NSG software translates ISUP to SIP5. NSG software packetizes the voice6. VoIP Packets sent to IP Network

SS7 to SIGTRAN / Megaco Gateway(distributed network intelligence – scales better for service providers)

1. SS7 traffic arrives at NSG

2. TDM Voice arrives at NSG

3. SS7 Stack decodes protocol up to MTP2

4. SS7 Stack converts MTP2 to M2UA (SS7 over IP)

5. Softswitch decodes SS7 protocol

6. Instructions sent to NSG via Megaco from Softswitch

7. NSG software packetizes the voice

8. VoIP Packets sent to IP Network

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.

No need for special licenses

Its just a choice you make when you configure the Gateway – Great flexibility!

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 largesoftswitch vendors thatservice providers use


Services

• SS7 is a complex protocol

– Will offer Certification Training

• Always quote with Services:

– Getting Started Packages – 8 hours of professional services @ $1600 – not discountable

– Annual software support and maintenance packages (s/w upgrades and updates, telephone support)• On appliances: 5% on MSRP

• On software: 20% on Software License price

• Not discountable


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

• The message is:– We are here to support your certifications efforts

– Our Trillium stack provides us with great confidence of compliance

COMPETITION

• 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.

Open Source SS7


• Proprietary H/W design

• TMG800 (1-8 T1/E1) , TMG3200 (8-64 T1/E1)

• Pricing OK, poor channel coverage

• Does not support SPIROU ISUP (FT variant)

• Patton OEMs TMG 3200 under the 10K Series

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

• 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.
