Using Digium's Asterisk® software and standard PC hardware, one can create a telephony environment that includes all of the sophisticated features of a high-end business telephone system.
Using an industry-standard bursting, bus-mastering interface chip that is found within millions of PC systems worldwide, and Digium VoiceBus Technology, the AEX410 eliminates the requirement for external gateways, with industry-leading performance and price. The trunk and station modules are interchangeable, allowing the creation of any combination of interfaces. The optional hardware echo cancellation module provides 1024 taps (128 milliseconds) of echo cancellation for superior voice quality on both trunk and station interfaces. Scaling of this solution is accomplished by adding additional AEX410 or other Digium analog interface cards. >>> [Please click on Image for more details]

Like our PCI-based TDM800P, the AEX800 provides an industry first with 8 standard two-wire, RJ-11 interfaces on a single card bracket. This eliminates the need for multiple brackets, external dongles, or splitters. In doing so, the AEX800 reduces part complexity, cable clutter, and points of failure.
The AEX800 contains two module banks. Each bank supports up to four analog interfaces and may be filled either with one standard Digium® quad station (S400M) or line/trunk (X400M) analog module, or up to two standard Digium single analog station (S110M) or line/trunk (X100M) modules, enabling the creation of any combination of ports.
The optional VPMADT032 hardware echo cancellation module provides 1024 taps (128 milliseconds) of echo cancellation for superior echo cancellation on both types of analog interfaces.
If the hardware echo cancellation module is not installed, the AEX800 may be used in conjunction with Digium's High Performance Echo Cancellation (HPEC) software, a commercial and toll quality hybrid echo cancellation solution.
Digium's HPEC provides 16ms to 128ms of selectable near-end ITU G.168 compliant echo cancellation in software.
Using this card in concert with Digium's Asterisk® software, standard PC hardware, and the Linux® OS, you can create SMB or SOHO telephony environments capable of satisfying the needs of small or medium business applications at an industry-leading price. >>> [Please click on Image for more details]

Using Digium's Asterisk Open Source PBX software and standard PC hardware, one can create a telephony environment that includes all the sophisticated features of a high-end business telephone system.
Using an industry-standard bursting, bus-mastering PCI interface chip that is found within millions of PC systems worldwide, and Digium VoiceBus™ technology, the TDM2400P eliminates the requirement for separate channel bank and T1 interface cards, at an industry-leading price. The quad-FXO and quad-FXS modules are interchangeable, allowing the creation of any combination of interfaces. The optional hardware echo cancellation module provides 1024 taps (128 milliseconds) of echo cancellation for superior echo cancellation on both FXO and FXS interfaces. Scaling of this solution is accomplished by adding additional TDM2400P cards. >>> [Please click on Image for more details]

Using Digium's digital hardware, Open Source Asterisk PBX software, and a Linux PC, users can create an intelligent telephony environment which includes all the sophisticated features of a high-end PBX/Voicemail platform.
The B410P is a half-length, full-height universal 3.3V and 5.0V 32-bit PCI 2.2 card supporting four BRI S/T interfaces. Each of the four ports of the B410P can be independently configured for TE or NT mode. The B410P features on-board hardware echo cancellation performing 64ms or 512 taps per channel for each of the eight voice channels. >>> [Please click on Image for more details]

Used in conjunction with Asterisk®, the TE122 can be used to deliver a wide range of PBX and IVR services to the network or handset including Voicemail, Call Conferencing, Three-way Calling, and VoIP Gateways.
The TE122 is a single span, selectable T1 (24-channel), E1 (32-channel), or J1 (24-channel) card. The card utilizes Digium's VoiceBus™ technology. VoiceBus technology allows the TE122 to use an industry standard bus-mastering PCI interface, as found in millions of PCs worldwide, to maximize system compatibility and eliminate system conflicts. Improving upon the prior TE120P which does not offer expansion capabilities, the TE122 may be combined with Digium's VPMADT032 echo cancellation module to deliver 128ms of echo cancellation across 30 channels in E1 mode or 24 channels in T1 mode. Bundled with the VPMADT032, the product SKU is TE122B.
The TE122 supports both voice and data modes on its single span. For example, the card can support 12 channels dedicated to voice, routed directly to the Asterisk Open Source PBX, and 12 to data, handled by the underlying Linux operating system, thus eliminating the need for an external router. The TE122 works in both 3.3V and 5V PCI slots by auto detecting the slot's voltage.
By utilizing our TDMoE (TDM over Ethernet) technology, an exclusive Digium process, you can easily connect multiple PCs equipped with the TE122 and achieve voice quality on par with single PBX implementations. Scalability for this product is derived from adding multiple TE122 cards to each individual PC. Add additional cards as you need them for your expanding applications.
The TE122 supports industry standard telephony and data protocols, including both RBS and Primary Rate ISDN (PRI) protocol families for voice and PPP, Cisco HDLC, and Frame Relay data modes. The board drives both line-side and trunk-side interfaces, including call features. >>> [Please click on Image for more details]

Digium's TE220 PCI Express card provides termination of up to 60 channels of voice or data across two E1, T1, or J1 interfaces in a PCIe x1 form factor. Selectable on a per-port or per-card basis, the TE220 allows E1 and T1 circuits to be mixed with full channel synchronization. Supporting PCIe x1, the TE220 may be used in any available PCIe 1.0 compliant slot - 1x, x4, x8, and x16 without considerations for voltage selection or lane size.
The TE220 may be combined with Digium's VPMOCT064 Octasic DSP-based echo cancellation module (not shown in picture). The VPMOCT064 provides the G.168 algorithm which has been labeled a benchmark for echo cancellation and performs 128ms (1024 taps) of echo cancellation across all 60 channels in E1 mode or all 48 channels in T1/J1 modes. Bundled with the VPMOCT064, the product SKU is TE220B.
Digium has designed the TE220 to be fully compatible and integrated with Asterisk Business Edition, AsteriskNOW, and open source Asterisk.
The TE220 supports industry standard telephony protocols including North American and European Primary Rate signalling as well as standard Robbed Bit, Channel Associated Signalling in addition to standard PPP, HDLC, and Frame Relay data modes. >>> [Please click on Image for more details]

The TE412P is a bundling of our leading TE410P product and our new VPMOCT128 Octasic DSP-based echo cancellation module. The VPMOCT128 provides a certified carrier-grade algorithm that has been labeled a benchmark for echo cancellation. This new module improves upon our older VPM400M and TE411P/TE406P products. With the VPM400M, 16ms or 128taps of echo cancellation were possible across 128 channels. The new VPMOCT128 enables users to eliminate echo tails up to 128ms or 1024 taps across all 128 channels in E1 mode or 96 channels in T1/J1 modes. Further, this module takes advantage of the Octasic Voice Quality Enhancement to provide superior sound quality on all calls.
Digium has designed the TE412P to be fully compatible with existing software applications and it is fully integrated with the Asterisk Open Source PBX/IVR platform. Also, the open source driver supports an API interface for custom application development. With the combination of Digium hardware and Asterisk software, numerous combinations of telephony configurations are possible. From the traditional PBX to VoIP Gateways, Digium solutions are paving the way for a new generation of w orldwide communications.
The TE412P supports industry standard telephony and data protocols, including Primary Rate ISDN (both N. American and Standard Euro) protocol fam ilies for voice, PPP, Cisco, HDLC, and Frame Relay data modes. Both line-side and trunk-side interfaces are supported, also included are advanced call features. The TE412P is for use only with a 3.3 volt PCI slot. >>> [Please click on Image for more details]
