Digium TDM410P Analog Interface Card Overview

The Digium® TDM410 is a half-length PCI 2.2-compliant modular gateway card for connecting analog telephone stations and analog POTS lines through a PC. It supports a combination of up to four station or trunk modules for a total of 4 lines.

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 TDM410 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 TDM410 or other Digium analog interface cards.

Digium Analog cards, with there interchangeable single and quad FXS and FXO modules can eliminate the requirement for seperate channel banks or access gateways. Digiums commercial, toll-free quality High Performance Echo Cancellation (HPEC) software is available to our analog customers at no additional cost. The optional VPMADT032 hardware echo cancellation module provides the same toll-quality HPEC but without the perfoamce inpact of a software based solution. Scaling of an analog card solution is accomplished by adding additional cards and FXO / FXS modules.

Digium TDM800 Digital Interface Card Overview

The Wildcard TDM800P is a half-length PCI 2.2-compliant, 8 port card for connecting analog telephones and analog POTS lines through a PC. It supports combinations of FXS and/or FXO modules for a total of 8 lines.

The TDM800P provides an industry first with 8 standard two-wire, RJ-11 interfaces on a single PCI bracket. This eliminates the need for multiple brackets, external dongles, or splitters. In doing so, the TDM800P reduces part complexity, cable clutter, and points of failure.

The TDM800P contains two module banks. Each bank supports up to four analog interfaces. The module banks may be filled either with one standard Digium® quad analog module (FXS – S400M, FXO – X400M), or up to two standard Digium® single analog modules (FXS- S110M, FXO – X100M) enabling the creation of any combination of ports

The optional hardware echo cancellation module provides 1024 taps (128 milliseconds) of echo cancellation for superior echo cancellation on both FXO and FXS interfaces.

If the hardware echo cancellation module is not installed, the TDM800P 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 SME or SOHO telephony environments capable of satisfying the needs of small or medium business applications at an industry-leading price.

Digium Switchvox: Different Things to Different Businesses

Guest Blogger: Randy Kremlacek, president, Teledynamic Communications

We’ve sold traditional Nortel phone systems since 1987 and 3Com phone systems since 1999. We could see the writing on the wall in 2009 and decided to replace those two manufacturers with Digium’s Switchvox. In what we thought was a bold and somewhat risky move, has come to become one of our best business decisions we’ve ever made.

In the past, we (just like our fellow traditional PBX competitors) had to make the Nortel or 3Com product fit into every business. If a customer needed something a little special that was always a big deal and a big expense. Expensive licenses, dedicated servers and complicated installations would make the solution painfully expensive. Not so, with our new PBX Swiss army knife, Digium’s Switchvox.

Recently, we installed a system at a local taxi cab company, an organization with tremendous incoming calls.  They wanted to do a database lookup and present the call with the client record. They also wanted to record their calls. A day’s worth of set up and they had their solution.  Their alternative was a traditional PBX at $10,000 more.

We had another customer who wanted to change their call handling for their outside sales and service reps. Before Digium, the outside reps would give their personal cell phone numbers to customers.  That presented many problems; the most significant one is that the company was completely out of the loop in call handling and customer communications. We were able to deploy a Switchvox system and now all the incoming customer calls go through the company PBX where they get re-routed automatically.  And mobile employees are enjoying their newfound communications capability with Switchvox’s mobile application for iPhones.

We’ve also come to the rescue of many an unhappy hosted customer. They nearly jump up and kiss us when we tell them that they can re-use their existing phones on Switchvox. None of the proprietary manufacturers can do that natively. Plus, they are pleasantly surprised to learn that they get the same powerful features as they did from their hosted provider, but without the big monthly bill.

Then there are the customers that buy (no, “insist on”) a product that is based on the SIP standard and is not hardware intensive. The PBX is rapidly becoming just another application on the network and Switchvox fits right into that overall shift from proprietary to a communications application.

Lastly, we’ve installed several Switchvox systems for customers who don’t care a bit about technology, standards or sophisticated features. For those Digium customers, they value the affordable price, flexibility, ease of administration and the wide variety of phones from which to choose.

In short, Switchvox can be many things to many companies – a powerful unified communications platform, an inexpensive customizable PBX or just a no frills telephone system. We and our customers love it!
