11 Overview of the Dialogic IMG 1010 Integrated Media Gateway Topic Location: Introduction Introduction The IMG 1010 is a unique carrier-grade VoIP gateway solution that offers customer s significant capital and operational savings while simultaneously speeding time to market. The IMG is unique in its ability to serve as an SS7 signaling server and media gateway with media processing capability all in one. With up to 768 channels in a 1U footprint that can be racked and stacked plus software licensing for costeffective in-service growth, the IMG 1010 is the solution for a wide variety service providers media gateway needs. Service providers can use the IMG 1010 to quickly and cost-effectively add new VoIP capacity while enabling long term migration to an all-voip environment. Service providers can rapidly provision and maintain a network of IMG 1010s using the GateControl EMS, a centralized management application with a user-friendly GUI for provisioning, monitoring and maintenance. Routing and translations on the IMG 1010 are significantly more robust than what many Service providers are used to finding in a VoIP gateway. The IMG 1010 comes with Dialogic's patented Programmable Protocol Language for rapidly developing PSTN and IP network signaling variants. This unique capability allows IMG 1010 customers to implement advanced and proprietary SIP interoperability features on their own. Where Flexibility Meets Performance Dialogic s Integrated Media Gateway (IMG) 1010 is a powerful, efficient, carriergrade VoIP media gateway that performs two-way protocol conversion between circuit-switched networks like the Public Switched Telephone Network (PSTN) and packet-switched networks like the Internet. This VoIP media gateway provides service providers and enterprises with unparalleled price performance, reliability, and flexibility. The Integrated Media Gateway reduces the cost and complexity of implementing new services by combining PSTN and packet signaling, SS7 continuity tests, and media (tones and announcements) in a cost-effective, easy-to-manage, compact (1u) shelf. Flexibility and Interoperability You can use the Integrated Media Gateway as a VoIP Gateway, VoIP Transcoder, or back-to-back SIP User Agent. The IMG 1010 ensures interoperability with a wide range of VoIP networks by simultaneously supporting Primary Rate Interface (PRI) and SS7, plus the packet network protocols SIP and H.323. You can implement protocol changes yourself quickly and efficiently, using Dialogic's patented Programmable Protocol Language (PPL). The Integrated Media Gateway supports advanced media capabilities without impacting VoIP channel processing. The IMG has undergone successful inter-operability testing with a wide spectrum of both VoIP and PSTN gateways. Reduced Capital Expenses, Faster Time to Market 1

12 Product Description This VoIP media gateway lowers initial cost because it supports full interoperability between ISDN, SS7, SIP, and H.323 across multiple gateways. So you can roll out new enhanced telecommunication offerings without buying, integrating, or managing third party softswitches, signaling gateways, application servers, FAX servers, media servers, proxy servers, or registration servers. While the Integrated Media Gateway can be configured for cost-effective entry-level requirements, it also allows you to seamlessly scale and gracefully upgrade your networks. And by using a single platform to provide rich application services across multiple networks, you significantly reduce the time, effort, and expense required to develop and deploy new services. Reduced Operational Expenses The Integrated Media Gateway 1010 also directly lowers your ongoing expenses. With signaling and media supported in a single platform, the cost and complexity of implementing new services is reduced, as are training, sparing, OAM&P, environmental, service agreement, and other costs that increase each time a new platform is deployed. And because the Integrated Media Gateway 1010 supports up to 768 channels in a 1U footprint, it can reduce rack space costs by up to 50%. Carrier-Grade Reliability "Carrier-grade" means more than having a hot-swappable fan tray. It means having 1+1 hot standby support for all active components. It means the ability to upgrade systems while they are in service. It means separating transport, signaling, and OAM&P to reduce susceptibility to intruders and to ensure better system performance. Improved Network Performance By integrating multiple network functions into the gateway, the Integrated Media Gateway 1010 improves network performance. It eliminates call hand-offs and redirection from box to box, improving call setup time and accelerating cost-effective integration of enhanced services. Investment Protection Dialogic has a long history of ensuring compatibility between existing systems and new offerings, without forklift upgrades. Whether service providers are concerned with new network protocols, new service offerings, or powerful new chip technologies, they can be sure that the Dialogic equipment they invest in today will be economically viable for many years to come. With the IMGs compact package, integrated SS7, and rich media processing capabilities, you can improve call quality while reducing your costs. New services, improved flexibility, investment protection, and higher quality, all at a lower cost and greater efficiency. Dialogic's Integrated Media Gateway 1010 is the gateway platform of choice for service providers and enterprises worldwide. Dialogic Corporation - IMG Printable WebHelp 2

13 Example IMG 1010 Network Topic Location: Introduction In the example shown below, a wholesale carrier has POPs (Points of Presence) in Los Angeles, New York, and Miami. New York is the Main POP, which houses the NOC (Network Operations Center) and IMG server. The network has two separate SS7 connections, an F-link in Los Angeles to the ILEC and an A-link to Illuminet in New York, which allows them to connect to carriers out of New York and Miami with one point code. The role of the IMG Gateway Controller is to manage all of these connections and allow SS7 calls that come into Miami to be serviced over the New York signaling links. The IMG Gateway Controller will have routing information stored in all of the nodes that will allow calls to be routed between cities seamlessly. Dialogic Corporation - IMG Printable WebHelp 3

17 An Overview of VoIP on the IMG Topic Location: Product Description > VoIP Overview The IMG will perform a two-way conversion between circuit-switched data (TDM) and packet-switched data (VoIP). A conversion is required when going from circuit switched data (TDM) to packetized voice applications such as the Voice over Internet Protocol (VoIP). Circuit-switched voice is converted to IP packets using compression algorithms that can increase capacity toward the IP network side. The IMG can also integrate media resources over IP technology. One of the benefits to the IMG is that it supports modifying the parameters of an individual call while the call is active. This is needed to be able to change the quality of service at any instant without losing the call. Integrated Media Resources Integrating media resources using IP technology provides many advantages. Typically media resources are connected by T1, E1, or J1 interfaces that consume one 64 Kbps port per call. This limits the capacity of the system. The IMG integrates media resources over IP using the standards-based Real-Time Protocol (RTP). Integrating media resources using standards-based technology allows media resources to be shared between the IMG and other network infrastructure. Packet switching to media resources allows the application to benefit from voice compression and increasing capacity on the application. This flexibility allows the IMG and the applications to scale independently and incrementally as needed which eliminates excess hardware. Summary of VoIP Features Supports SIP RFC 3261 Supports SIP RFC 3581 Supports H.323 V2 Supports up to 512 VoIP resources.

19 Supported Codecs Topic Location: Product Description > VoIP Overview In ClientView under the IP Bearer Profiles Object New Vocoder Entries can be defined. Each of these entries can have a different codec configured. Attributes such as payload type and size (preferred, minimum, and maximum) can be configured. When there are multiple vocoder entries configured under the IP Bearer Profile object a priority order can be configured that is used in the H.245 Terminal Capability Exchange for codec negotiation with other network elements. The IMG supports the following codecs: See Table Below CODEC SIP H.323 G.711 alaw/ulaw Yes Yes G kbps Yes Yes G kbps Yes Yes G.729 Yes Yes G.729E/G ( ER2 Yes Not Supported and above) T.38 Yes Yes ilbc 20 ms Yes Yes ilbc 30 ms Yes Not Supported AMR Yes Not Supported EVRC Yes Not Supported G /G.721 Static Yes Not Supported Payload G /G.721 Dynamic Yes Not Supported Payload GSM-FR Static Payload Yes Not Supported GSM-FR Dynamic Payload Yes Not Supported Codec Descriptions G.711 International standard for encoding telephone audio on an 64 kbps channel. It is a pulse code modulation (PCM) scheme Two different variants: A-law and mu-law. A-law is the standard for international circuits. Always used for Fax or Modem Bypass modes (A-law or u-law allowed) G.723 Designed for video conferencing / telephony over standard phone lines, and is optimized for realtime encode and decode. Part of the H.323 standards for video conferencing. G /G.721 G is a speech codec used in both a-law and u-law variants 9

20 Product Description Uses ADPM (Adaptive Differential Pulse Code Modulation) to allow for reduction of bandwidth Converts 64 kb/sec a-law or u-law PCM Channel to a 32kb/sec which is about half the rate of G.721 Primarily used in international trunks Standard Codec used for DECT wireless phone systems Can be negotiated as a Static or Dynamic Payload type Uses Profile 6 or Profile 7 G Kbps encoded bit stream rate Discontinuous transmission support (DTX) using Voice Activity Detection (VAD) and Comfort Noise Generation (CNG) G.729A and G.729A/B supported. G.729 Annex B Support There is a drop down menu where the user can decide whether annexb will be used. The choices are annexb=no, annexb=yes, or annexb=not Used. AnnexB is currently supported only in G.729. When configuring the G.729 codec in ClientView the annexb field is defaulted to "Yes". See Below for more information. This feature is configured using the Vocoder Entry pane. If the user selects "No" in the drop down menu then the media attribute "annexb=no" is sent by the IMG in the SDP portion of the SIP message when enforcing the use of the G.729 payload type. If the user selects "Yes" in the drop down menu then the annexb message will not be displayed in the SDP portion of the SIP message. This value is implied when unspecified in the SDP. If G.729 Codec is not being used then ClientView will disable the AnnexB support field. G.729 E/G ( ER 2 and above) SIP Only Codec defined by the ITU RFCs 3551 & 3555 Provides increased voice quality Uses dynamic payload types ( range), which must be agreed on by both endpoints of a call (using SIP/SDP). G.729E is a higher rate version of G.729 designed to provide higher quality for background noise conditions, music, and tandems. This mode is better for music, and it has greater complexity than the original G.729 coders Mandating a codec in this range provides high quality, low-bandwidth performance for on-net calls and ensures the highest possible performance for applications such as IVR systems. In addition, it provides superior background noise handling, as well as medium quality music carriage. Available in 10, 20 or 30 ms payload sizes Supports all attributes that G.729 supports (silence suppression, RTP redundancy, etc.) Annex G defines the silence suppression characteristics (VAD/CNG) for G.729E. G.729E and G.729E/G are essentially the same. According to RFC 3555 (defines MIME support for codecs), the annexb parameter can be used to enable/disable silence suppression in IP signaling negotiation. 10

21 Supported Codecs An example of the media representation in SDP for describing G.729E/G might be: m=audio 5104 RTP/AVP 96 a=rtpmap:96 G729E/8000 a=fmtp:96 annexb=no a=ptime:30 a=maxptime:60 ilbc (internet Low Bitrate Codec) SIP Only Defined by RFC 3591 and RFC 3592 Available in 13.3 kbps (30 ms encoding frame length) or 15.2 kbps (20 ms encoding frame length) versions Uses dynamic payload types ( range), which must be agreed on by both endpoints of a call. Designed for narrow band speech (64kbps). Decoding algorithm does not depend on previous packets, therefore it is excellent at handling packet loss. Mandatory codec required for the released CableLabs PacketCableTM 1.1 audio/video codec specification for multimedia terminal adapters (MTAs) and media gateways. EVRC (Enhanced Variable Rate Codec) SIP Only Requires Dialogic license. Defined by RFC A CDMA codec defined by 3GPP2. Used in millions of CDMA handsets. Sent in 20 ms output frames of 3 different sizes: Rate 1, Rate ½ or Rate 1/8. Output frame rate is chosen based on analysis of input frames (dynamically). Two payload modes: header-free and interleaved (only header-free in current release). Silence suppression supported internally (not configurable). Uses dynamic payload types ( range) GSM-AMR (Global System for Mobile - Adaptive Multi-Rate) Requires Dialogic licensing. AMR codecs (narrow and wide band) originally defined by ETSI for GSM. Only AMR-NB supported in current IMG release. Mandatory codec for 3G cellular systems. Uses dynamic payload types ( range) Supports eight narrow-band speech encoding modes with bit rates between 4.75 and 12.2 kbps. These rates can be adjusted dynamically during a session. Speech encoding performed in 20 ms frames. Multiple 20 ms frames can be encapsulated into a packet (maxptime in SDP defines max frames per packet). Reception of multiple frames in a packet allowed, but only one frame per packet will be transmitted kbps version of AMR-NB is defined by the GSM-EFR standard. 7.4 kbps version of AMR-NB is defined by the IS-641 codec in TDMA. 6.7 kbps version of AMR-NB is defined by the PDC-EFR standard. Silence suppression supported internally (not configurable). 11

33 An Overview of ISDN on the IMG Topic Location: Product Description > ISDN The IMG supports (ISDN) Integrated Services Digital Network for a complete digital telephone/telecommunications network which will carry voice, data, and video over an existing telephone network. The IMG supports 128 Kbps high-speed and highbandwidth service. ISDN non-compressed (512 Kbps compressed) can also provide on-demand service and can connect up to eight devices simultaneously with each device being call-managed. The basic configuration is 23B+D (Primary Rate Interface) and 30B+D outside of North America. The IMG interfaces to various equipment types supporting the ISDN PRI protocol, including tandem (Class 4) switches and end office (Class 5) switches. The IMG ISDN PRI implementation is based on ITU-T Q.921 and Q.931 specifications. Each implemented variant references the appropriate interface document supplied by the equipment manufacturer. The interface document is usually a variant of the ITU-T recommendations. The IMG supports up to 32 D channels. Each D channel provides the High Data Link Control (HDLC) communications over T1, E1, or DS3 on one timeslot on the span. Each D channel can control up to 19 other spans in addition to the span on which it is located. The IMG supports sending UUI (User to User Information) between called and calling parties during the Setup, Clearing, and Active Phase of the Call. The purpose of the User to User Information support is to pass specific information not pertaining to the call from one user to another. National ISDN PRI NI 2 The IMG supports National ISDN PRI NI 2. National ISDN PRI supports Non-Facility Associated Signaling (NFAS), allowing up to 30 DS1 interfaces and the D channel backup procedure, as well as B channel availability and provisioning. Connection endpoint variants are defined for National ISDN User side and Network side. Depending upon your provisioning requirements, the IMG supports one D channel per span [Facility Associated Signaling (FAS)], or one D channel managing up to 20 spans [Non-Facility Associated Signaling (NFAS)]. The IMG supports controlling a total of 32 spans using all FAS D channels, or controlling up to 20 spans per NFAS D channel (to a maximum of 64 spans per system). You can intermix both FAS and NFAS D channels with each supporting a different variant. Dialogic Corporation - IMG Printable WebHelp 23

35 An Overview of RADIUS on the IMG Topic Location: Product Description > RADIUS Overview The IMG uses Remote Authentication Dial In User Service (RADIUS) protocol for streaming the Call Detail Records (CDR). The implementation is compliant with RFC 2865 and RFC The RADIUS messages are sent to external RADIUS servers. The IMG RADIUS interface generates an ACCESS, a START & a STOP Request for the inbound leg and a START & STOP Request for the outbound leg of the call, as well as data associated with the INVITE, the 200 OK, the BYE and the CANCEL methods for those legs utilizing a SIP protocol. Specifications The IMG implementation of RADIUS is based on the following RADIUS RFCs: RFC Remote Authentication Dial-In User Service (RADIUS) RFC RADIUS Accounting Formats The IMG 1010 supports the Cantata RADIUS formats, which Includes some attributes defined by RFC 2865 and RFC 2866, as well as Cantata Vendor Specific Attributes (VSA). Scenarios The IMG 1010 supports RADIUS Authentication and Accounting. IMG 1010 customer has the option of using one of the following scenarios: Authentication and Accounting In this case an Authentication Server and an Accounting Server are both assigned to the RADIUS client on the IMG. Accounting only In this case only an Accounting Server is assigned to the RADIUS client on the IMG. Authentication only In this case only an Authentication Server is assigned to the RADIUS client on the IMG See RADIUS Scenarios for more details. As per RFC 2865 and RFC 2866, the IMG 1010 uses port 1812 for Authentication and port 1813 for Accounting by default. But these ports are also configurable. The Authentication and Accounting servers could be the same entity, in which case both servers will have the same IP address. Or they could be different entities with different IP addresses. The RADIUS attributes and VSA s included in the messages will vary based on the protocol for used for a specific side of the call, depending on whether it is a TDM protocol (SS7 or ISDN) or IP protocol (SIP or H.323). The User name and Password values configured for the Authentication Server used will be included in the user name and password attributes in the Access Request message sent from the IMG. 25

36 Product Description RADIUS Server Redundancy The IMG 1010 supports an Active Standby redundancy scheme. Redundancy logic is independent for Authentication and Accounting Servers. When configuring RADIUS servers you may create them with an initial priority preference. The IMG will begin using the preferred Server(s) and switchover to an alternate server after detecting a communication failure to the currently active server. Once the switchover occurs all future Radius messages will flow to the newly active server until a failure occurs on this server. If an error is detected in trying to send a Radius message to this newly active server, the IMG will attempt to switch again back to the previously active server. This behaviour is repeated, until a working server is detected. If the IMG fails to connect to a RADIUS Server an alarm will be sent. You can monitor alarms using EventView. Typically when a RADIUS message needs to be sent to a server, it is assembled and passed to the OS for transport to the currently active server. These servers are configured to send the message, wait 2 seconds and then retry sending the message an additional 3 times. Therefor a RADIUS message will be sent a total of 4 times, with 2 second intervals, before attempting a switchover to the next server, if one is configured. The switchover behaviour is coupled to the message type. Therefore an Accounting Server switchover is independent of an Authentication Server switchover. Under typical call load it will take a while for the switchover to complete since the IMG may have many RADIUS messages queued up to the failed server. Each of these messages must fail and be retried on the newly active server following notification of the send failure. NOTE: A negative response does not constitute a server failure. Supported Packet Types Access-Request Sent to a RADIUS server - conveys information used to determine whether a user is allowed access to a specific NAS, and any special services requested for that user. Access-Accept Sent by the RADIUS server - provides specific configuration information necessary to begin delivery of service to the user. Access-Reject Sent by the RADIUS Server if any value of the received Attributes is not acceptable Accounting-start Accounting-stop RADIUS Server Debug Mode You can configure your RADIUS Client in Debug Mode so that calls will be completed whether the RADIUS server is active or not. The IMG will not require authentication for the RADIUS server to complete a call and no billing information will be logged. You enable RADIUS Debug Mode using the RADIUS Client screen. RADIUS Server Failure Alarm 26

37 An Overview of RADIUS on the IMG The IMG provides automatic alarming notification to IMG users when a Radius Server has changed states and can no longer be accessed. The alarm, reported in EventView, will include the RADIUS Server Type (Access, Accounting), the Server ID, the mode of the Radius Server (normal, debug), the state of the Radius Server and the IP address.
