Alcatel-Lucent ISAM Voice For smooth migration to NGN/IMS
The Alcatel-Lucent Intelligent Services Access Manager (ISAM) Voice component provides Voice over IP (VoIP) gateway functionality to the Alcatel-Lucent ISAM family of products. With ISAM Voice, service providers are able to connect customer premises legacy POTS or ISDN to Next-Generation Networks (NGNs) and IMS networks.
Dealing with PSTN migration As an incumbent service provider in an increasingly saturated fixed voice market, you face the declining profitability of your PSTN. With severe competition, the average price per minute of voice calls is decreasing; moreover, cable operators are offering attractive service bundles; alternative VoIP providers are offering low tariffs using third-party access networks, and some customers are abandoning fixed voice lines in favor of mobile phones.
IP Voice Transformation with Alcatel-Lucent ISAM Voice Bundling opportunities with Alcatel-Lucent ISAM during IP voice migration PSTN transformation is driven by fierce competition, erosion of voice revenue, network obsolescence, IP network transformation, bringing fiber closer to the end user, and the desire to introduce new and compelling voice-related services. As a result, you need a flexible solution to act on these challenges.
With the Alcatel-Lucent ISAM family, you can also support video penetration in flexible deep-fiber scenarios. This enables the optimum reuse of the copper plant and improved subscriber high-capacity reach. With ISAM Voice, the Alcatel-Lucent ISAM family also supports the deployment of legacy PSTN interfaces and NGN/IMS media gateway functionality over the same platform in order to facilitate network convergence without discontinuity in subscriber offerings.
What Alcatel-Lucent ISAM Voice offers Alcatel-Lucent ISAM Voice components provide PSTN-quality VoIP, completing the future-safe, multiservice ISAM access solution by enabling innovative triple play services. PSTN voice in an NGN/IMS access scenario In cases where customers decide to migrate via a two-step approach, Alcatel-Lucent ISAM Voice enables the migration from NGN to the IMS core with a simple software upgrade.
An advanced IP/Ethernet platform One investment to cover all needs Minimized OPEX in the installed plant IP/Ethernet technology is at the core of the Alcatel-Lucent ISAM family. These technologies aggregate various types of services from IP-enabled line cards to a Gigabit Ethernet core, including legacy POTS and ISDN subscriber interfaces.
Increased deployment flexibility With Alcatel-Lucent ISAM Voice, you can also offer voice support with the overlay of existing DSLAM installations. Alternatively, you can choose a pre-seeding strategy: first, by installing Alcatel-Lucent ISAM in order to deliver xDSL, while precabling the rack to introduce POTS or ISDN boards at a later stage. To support this strategy, the ISAM platform provides a complete and dense variety of DSL transmission technologies (ADSL, ADSL2, ADSL2 plus, VDSL2, S.HDSLbis).
Key ISAM voice features Signaling protocols Emergency calls with H.248/Megaco Alcatel-Lucent ISAM Voice implements H.248/Megaco and SIP signaling to connect to NGN/IMS networks. Ten percent of the call capacity is always reserved for emergency use, in addition to the 512 active, regular calls handled by the NVPS with H.248. Because each line card has its own user agent, ISAM can always initiate an emergency call. ISAM call control and traffic dimensioning with H.
Combo solutions Line testing Voice lines provided by Alcatel-Lucent ISAM Voice can be delivered from a combo shelf on which voice and DSL are both provisioned. The combo shelf enables simplified cabling with MDF, zero-touch service provisioning and flexible growth of voice or xDSL services. Metallic Test Access (MTA) is supported for POTS.
The Alcatel-Lucent advantage Alcatel-Lucent is best positioned to help you achieve network optimization by offering triple play services over a cost-effective, single, converged network. The Alcatel-Lucent ISAM family offers a future-safe, multiservice intelligent IP broadband access platform that provides wire-speed delivery of value-added digital services, including IPTV, VoIP, gaming and teleworking. With the incorporation of Alcatel-Lucent ISAM Voice, and a choice between H.
