The world marketplace for broadband entry is repeatedly rising. Independent market researchers declare that by 2007 there will probably be roughly 250 million broadband strains worldwide. Broadband entry, which is obtainable over DSL or cable infrastructure, is enabling numerous Voice over Broadband (VoB) companies, a few of that are supplied by suppliers who’re new to the sector of telecom. Internet Services Providers (ISP) have gotten Internet Telephony Service Providers (ITSP) by bundling voice companies with their information companies, and are focusing on residential and Small Office/Home Office (SOHO) prospects. Independent market experiences venture that from 20 million VoB strains in 2005, we’ll see over 90 million VoB strains in 2008.
A typical VoB community contains the next parts:
o Telephone Adapters for connecting residential and SOHO customers
o Softswitch and Application Server for name management, signaling, and community companies
o Media Server for enjoying tones and bulletins as properly for enhanced companies similar to conferencing
o Trunking gateways for interconnecting to the Public Telephone Switched Network (PSTN)
o Session Border Controllers (SBC) for interconnecting to different VoIP networks
AudioCodes’ wide selection of Media Gateways and Media Servers is finest suited to deploying a robust, dependable and scalable VoB community. With a complete product line, over a decade of expertise, and an enormous set up base, AudioCodes is the best vendor for the gateway and media server wants of any service supplier deploying a VoB community.

A member of the MediaPackTM sequence of analog VoIP gateways, the MP-20x sequence of Telephone Adapters is a cheap, innovative product, which permits connecting strange analog telephones or fax machines to the core of a VoB community. The MP-20x sequence sometimes connects to an present Broadband Internet machine (cable or DSL modem), and establishes a communications path with the Service Provider community by way of its IP Uplink connection. The following determine outlines 2 typical configurations on the residence and SOHO premises.
The MP-20x sequence gives as much as 2 VoIP ports for connecting as much as 2 POTS strains or fax machines. Supporting a wealthy set of subscriber calling options similar to caller ID, Call Forward, and Call Waiting, the MP-20x sequence maintains a uniform person expertise when migrating to VoIP companies.

Low Bit-Rate (LBR) vocoders (voice coders) can be utilized concurrently on each telephony ports to avoid wasting helpful bandwidth. The “Voice over Data” prioritization algorithm prevents degradation in voice high quality even throughout giant information transfers.
Advantages of deploying a Telephone Adapter
The MP-20x permits the Residential person to expertise the identical telephone service as beforehand. The person can preserve his POTS telephone which eliminates the necessity to study new details about the interface and usefulness of an IP-phone, permitting steady use of the telephone service by making use of the usual dial pad and flash hook. Residential customers who’ve a cordless telephone can proceed utilizing them transparently round the home. An extra benefit is {that a} fax machine with a separate quantity allocation could be related.

This reduces “support calls” to the service supplier and permits the residential person to have a smoother migration to VoIP.
Leveraging on the MP-20x routing capabilities, Voice Quality is assured due to prioritization of voice packets over information bursts, additional enhancing the “VoIP Experience”.
A future model of the MP-20x will assist a mix of 1 FXS and 1 FXO interfaces. This permits for fallback to PSTN in instances of degraded community high quality, permits incoming calls from the PSTN to the identical telephone and permits the routing of 911 calls by way of the PSTN to common PSAP.
Softswitch / Application Server
The MP-20x Series is designed for full interoperability with main Softswitches and SIP Application Servers for deployment in varied community environments. Over the years, AudioCodes has invested important effort in complying with main and evolving VoIP requirements.

Media Server
Media Servers present enhanced voice companies similar to community tone and bulletins, conferencing and Interactive Voice Response (IVR) capabilities, and messaging. Interoperable with main Softswitches and Applications Servers, the IPmediaTM Media Servers are managed to supply a fluent community operation.
Trunking Gateways
Media Gateways present a scalable means for interconnection with the PSTN consisting of a broad vary of interface signaling (CAS, ISDN, IUA, SS7, M2UA, M3UA). Controlled utilization of MGCP, Megaco/H.248 and SIP that are interoperable with main Softswitches, the MediantTM Media Gateways allow VoB operators to supply their prospects calling capabilities to and from different PSTN networks.
Session Border Controllers (SBC)
Session Border Controllers (SBC) allow VoB networks to see with different VoIP networks together with clearing homes which facilitate cheaper interconnection and scale back lengthy distance calling costs.
