Digium TDM413E

Digium TDM413E - 4 port modular card PCI 3.3/5.0V with 1 Station and 3 Trunk interfaces and HW Echo Can

The Digium Wildcard TDM410 board is a high-cost PCI 2.2-size modular Gateway board for connecting analog subscriber phones and analog PSTN lines to a personal computer. It supports combinations of up to four FXS or FXO modules in flat folding up to four lines.

With the help of an Asterisk Open Source PBX IP telephone exchange server and a basic PC, you can create a telephone network that provides all the complex and essential functions of daily telecommunications equipment for great business.

Based on Galouze standards, available on millions of computers around the world, the PCI interface, as well as Digium VoiceBus™ technology, pay-sets based on TDM410 take the place of expensive external gateways. In this case, the stench is characterized by low price and high productivity.

The FXS and FXO extension modules are interchangeable, allowing you to create any combination of interfaces.

Like Digium's front-end boards, the TDM410 board for increasing the transmitted data luminosity can be equipped with a hardware echo-muting module VPMADT032, which ensures echo-muting within 128 ms (1024 volts). In this case, the module, however, effectively processes all communication streams, both FXS and FXO. Whenever there is a signal, for echo attenuation, the High Performance Echo Cancellation (HPEC) software is used, which adheres to the G.168 specification and is more important in the range from 16 to 128 ms, based on the capabilities of the computer's central processor.

A scalable solution can be achieved by adding additional TDM410 or other Digium analog interface cards to the system.

Please note: the operation of FXS modules requires a large 12 V socket in the server power supply. VIN is not required for the operation of FXO modules.

Deciphering the smart values of TDM sets is available: TDM 4XYZ, where “TDM” means the same as Digium Wildcard TDM410, “X” means the amount of FXS mezzanine, “Y” means the amount of FXO mezzanine, and “B” means that this product is set, “E” means that the set includes the echo suppression module VPMADT032.
