VOIP CARD WIMAX CARD : WiMAX VoIP Solution

VoIP Solution Card for IP PBX Systems Solution

WiMAX provider Clearwire has made available its long-awaited PC card in its retail stores and online in almost all of its markets, according to Pali Research. Analyst Walter Piecyk said the launch should be perceived positively since it increases Clearwire’s target market. PC Card can be used in most laptops versus a modem’s size and power requirement that limit mobility.

‘The PC card launch will be a critical test for Clearwire on the market demand for broadband wireless services in the face of slowing growth in cable modems and DSL lines as well as the recent cancellation of muni-WiFi projects,’ noted Piecyk.

The future is here. Er, actually, it's in Australia. Sydney, to be precise. If you live in the Sydney environs, and are willing to shell out AU$349 ($255), plus AU$55 per month for a data plan, you can now get a WiMax card for your laptop, along with access to a pre-WiMax network that offers speeds you're not going to get from most other wireless networks (other than EV-DO, which costs much more in Australia). APC Magazine took a look at the card, and tested it on Unwired's network, and came away impressed with the speed of 750Kbit/s, which allowed them to reliably use Skype, download large files and get a clear, reliable, relatively latency free signal throughout the coverage area. Of course, that coverage area is pretty limited, so don't rush out and buy one of these just yet, unless, that is, you can look out your window and see the Opera House.

Motorola is stepping up to the plate, bringing all you wireless lovers the first WiMax-capable laptop card. The card brings high-speed, high-range wireless goodness straight to your lappy connecting with Clearwire Mobile's WiMax service (which covers 37 markets within California, Florida and Washington).

Clearwire got the FCC okay to support a wireless card on its 802.16e wireless network. Our guess is that it will be this Motorola Expedience card, which Clearwire itself designed before selling that hardware division to Moto. The card likely won't be out till late this year so there's no word on pricing. What we do know is that when it does come out, it'll only play nice with Vista and Windows XP. – Louis Ramirez

Asterisk VoIP Solution Card for IP PBX Systems Solution

VoIP Solution PCI Card for Voice Codec, Transcoding, Echo Cancellation, and VQE for Open Source VoIP Solution Systems Solution

SigC5561 VoIP Solution PCI card for Asterisk IP PBX server

SigC5561 card without PCI adapter, view of front bezel and bottom side. Configurable from 1 to 12 high-density Texas Inst TNETV3010 VoIP Solution chips. Each chip has six (6) cores capable of 32 channels each of carrier grade VoIP Solution, including echo can and voice codec

Overview

The SigC5561 PCI card utilizes Texas Instruments / Telogy TNETV3010 DSP devices to provide a high-density, low-cost packetization engine for Asterisk™ IP PBX and open source VoIP Solution systems. The TNETV3010 device yields a high ratio of channel capacity to cost and board space, providing up to 192 channels per device including full 128 msec echo cancellation, multiple voice codecs (see list below), G.711.1 packet loss concealment, VAD, CNG, DTMF functions and RFC 2833 relay, jitter buffer, and more.

The SigC5561 card complies with HMP (Host Media Processing) architecture and allows transfer of both TDM and packet data over PCI bus, providing a hardware engine for PC-based media gateway, softswitch, and transcoding server applications based on open source VoIP Solution software. Channel capacity scales from 192 to 2304 G.711 (PCM voice), 96 to 1152 G.729AB or iLBC, and 72 to 864 G.723 or GSM-AMR channels.

The SigC5561 board may also be used in ATCA, cPCI, VME, and other infrastructure platforms. Click here for more information about non-desktop PC configurations of the SigC5561 card.

SigC5561 card highlights include:

up to 2304 G.711 channels, 1152 G.729AB or iLBC channels, and/or 864 G.723 or GSM-AMR channels

configurable echo can, VoIP Solution and transcoding operation

each VoIP Solution channel independently configurable for echo can, voice codec, and other parameters

WinPath 7x7 network processor and direct GbE and 10/100 network RJ-45 connections

Voice codecs, echo cancellation, and voice quality monitoring are good examples of "DSP real-time processing" performed far more efficiently and at far lower cost using the SigC5561 card than using server arrays based on multi-core x86 processors. At higher channel capacities, for example 120 or more, adding one or more SigC5561 cards triggers a cascade of cost savings, eliminating LBR codec IP/royalty fees, reducing electric and cooling costs, and reducing required physical space. In effect, each server is maximized for efficiency and the waste and high cost caused by "motherboard farming" is eliminated.

VoIP Solution Solution Overview

In a typical VoIP Solution application, the SigC5561 card processes TDM channels of 64 kbps PCM (G711) voice, fax or data traffic. Voice data is optionally compressed via G729AB, G723, GSM-AMR, EVRC, iLBC, or other LBR codec. In addition, the SigC5561 card provides RTP, RTCP, or T.38 packetization of voice and fax data, and a comprehensive range of voice and data telephony functions.

In a typical transcoding application, the SigC5561 card transcodes between one type of LBR codec and another, for example between G729AB and G723, or G729AB and GSM-AMR, using embedded logic on the board to allow internal PCM loopback and framesize adjustment.

Mixed VoIP Solution and transcoding applications are supported.

For advanced applications, an optional WinPath network processor provides packet formatting, segmentation, reassembly, and routing functions directly on the SigC5561 card, without host intervention, including direct GbE or 10/100 interfaces to RJ-45 connectors.

PSTN Interface Options

There are three (3) ways to interface PSTN lines, also known as TDM or PCM data, to the SigC5561 card:

Separate multi-FSX/FXO, multi-T1/E1 or T3 PCI card(s). In this case, TDM data is transported on the PCI bus, between cards. Providers of T1/E1 and T3 cards include Digium, Sangoma, SBE, and more. This method is the least expensive and most flexible, but experiments show that reliable operation is limited to about 500 or so TDM channels over the PCI bus on 32-bit PCI motherboards.

Unified multi-T1/E1 or T3 card. In this case, the SigC5561 and another PMC form-factor card are combined on a dual site PCI carrier card, which allows TDM data to move between the two cards without PCI bus interaction. A typical dual carrier card configuration would combine a SigC5561 card and a wanT3 channelized DS3 card. The dual carrier method allows higher channel capacities due to direct inter-card TDM communication, free from impact of system activities involving the PCI bus. TDM channel capacities up to 2048 full-duplex channels are possible per SigC5561 card.
TDMoIP protocol. TDM-over-IP protocol, also referred to as CESoPSN, may be used. In this case, TDM data is transported on the GbE interface to the SigC5561 card, where it is "interworked" by the WinPath network processor into TDM format data and routed to the TDM side of the DSP farm. TDM channel capacities up to 2304 full-duplex channels are possible per SigC5561 card.

The above table shows channel capacities for TDM-to-IP operation. For IP-to-IP operation, channel capacity depends on the type of transcode. For most cases of transcoding between an LBR (low bit rate) codec and G.711, channel capacity matches the above table. But for transcoding between "asymmetric" LBR codecs, channel capacity is usually reduced by half. For more information on this subject, please call to discuss with Signalogic engineers.
