  • 5-year hardware warranty
  • Backed by Digium's Exceptional Satisfaction Program (ESP)


4-Port Card

The 400 Series cards support up to four (4) analog connections per card in your Asterisk system. Using Digium's single-port interface modules, 400 Series cards can scale from one (1) to four (4) ports.

The modular nature of the cards allows you to mix and match between line (FXO) and station (FXS) interfaces, giving you exactly the ports you need. The 400 Series cards are available in full-length PCI 2.2 and PCI Express form factors.


8-Port Card

The 800 Series cards support up to eight (8) analog connections per card in your Asterisk system. Using Digium's advanced quad-port interface modules, 800 Series cards can scale from one (1) to eight (8) ports.

The modular nature of the cards allows you to mix and match between line (FXO) and station (FXS) interfaces, giving you exactly the ports you need. Digium 800 Series cards are available in full-length PCI 2.2 and PCI Express form factors.


24-Port Card

The 2400 Series cards support up to 24 analog connections per card in your Asterisk system. Using Digium's advanced quad-port interface modules, 2400 series cards can scale from four (4) to 24 ports.

The modular nature of the cards allows you to mix and match between line (FXO) and station (FXS) interfaces, giving you exactly the ports you need. Digum 2400 Series cards are available in full-length PCI 2.2 and PCI Express form factors.


Digital Cards

Digium's super-reliable digital line cards connect Asterisk-based communication systems to T1, E1, J1 and ISDN-BRI interfaces.

  • RoHS compliant
  • Manufactured in an ISO 9001:2001 certified facility in the United States
  • MTBF greater than one (1) million hours
  • 5-year hardware warranty
  • Backed by Digium's Exceptional Satisfaction Program (ESP)


Single Span

Add up to 24 (T1) or 30 (E1) crystal clear digital calls to your Asterisk system with a Digium single span interface card. Available in PCI or PCI Express form factor, the single span cards use state of the art technology for unsurpassed call quality and system compatibility.


Dual Span

With a dual-span Digium card you can add up to 48 (T1) or 60 (E1) calls to your Asterisk communications system. With a five year warranty, an optional echo cancellation module and support from the Asterisk experts, Digium cards are the gold standard for PSTN connectivity.


Quad Span

Building a large-scale communications system with Asterisk? A Digium quad span card lets you up to four T1 or E1 circuits.  That's a total of 96 (T1) or 120 (E1) concurrent calls. All quad span cards come with Digium's Exceptional Satisfaction Program (ESP) risk-free guarantee, a five year warranty and support for the optional VPMOCT064 echo canceller.


Octal Span

Supersize your Asterisk application with the TE820.  Digium's highest density card, the TE820 adds up to eight T1 or E1 connections.  That adds up to 192 (T1) or 240 (E1) calls on a single slot.  The TE820 gives you the power to build large-scale Asterisk® applications that require high-performance, cost effective digital connectivity.


Euro ISDN BRI

Built exclusively for the European market, the B410P adds up to four EuroISDN BRI connections (8 concurrent calls) to you Asterisk system.  Each of the four ports of the B410P can be independently configured for TE or NT mode, making the B410P a flexible, cost effective means of adding BRI service to your Asterisk solution.


Hybrid Cards

The Digium Hx8 Series are high-performance, cost-effective hybrid analog and BRI telephony interface cards providing the capability to seamlessly integrate mixed-mode environments in a single device. Use the telephony card selector to identify the card that fits your requirements.


8 Port BRI/Analog Hybrid

Add both ISDN and analog in a single half-depth PCI or PCI-Express card slot.  The Hx8 Series interface cards add a combination of EuroISDN BRI and analog capability to your Asterisk solutions.  Hx8 cards support up to eight connections, including analog line (FXO) interfaces, analog station (FXS) interfaces, and digital ISDN BRI interfaces. 


Voice Compression

Get more out of Asterisk by offloading codec conversions to Digium's TC voice compression cards.  Software transcoding takes up host CPU cycles and can limit the capacity of your server.  TC cards are dedicated hardware transcoders; they drastically reducing the bandwidth consumed by each call without ever touching your host CPU. Our voice compression cards are capable of compressing/decompressing 120 channels of G.729 or 92 channels of G.723.1.



PCI Voice Compression Card

The TC400B is a bundle of the half-length, low-profile PCI-2.2 compliant TC400P base card and the TC400M voice processing module. The TC400B is designed to handle, in dedicated DSP resources, the complex codec translations for highly compressed audio as would otherwise be processed by Asterisk in software.


PCI Express Voice Compression Card

The TCE400B is a bundle of the half-length, low-profile PCI-Express x1 TCE400P base card and the TC400M voice processing module. The TCE400B is designed to handle, in dedicated DSP resources, the complex codec translations for highly compressed audio as would otherwise be processed by Asterisk in software.


Modules

Add-on hardware modules and accessories for analog and digital cards

Echo Cancellation Modules

For Asterisk users who connect to the PSTN, echo with the voice communication is possible and can be managed effectively with echo cancellation solutions from Digium. Asterisk itself offers a range of software-based open source echo cancellation routines that are moderately effective in eliminating the echo that most Asterisk users experience. However, there are cases in which these algorithms are not effective. To combat this, Digium offers a line of DSP-based echo cancellation modules for all of our analog and digital (T1/E1/J1) cards with the VPMOCT series modules.

Quad Channel Analog Modules

Digium quad channel analog modules allow 800 Series or 2400 Series telephony cards to terminate four (4) line (FXO) or station (FXS) connections per module.

Single Channel Analog Modules

Digium single channel analog modules allow 400 Series or 800 Series telephony cards to terminate one (1) line (FXO) or station (FXS) connections per module.
