Digium analog telephony cards are high-performance, highly reliable and cost-effective interfaces for POTS lines to your Asterisk solution. Multiple applications can be created to satisfy the business needs of any organization when using Digium analog cards in concert with Asterisk software, the Linux® operating system and standard PC/server platforms.
Digium's super-reliable digital line cards connect Asterisk-based communication systems to T1, E1, J1 and ISDN-BRI interfaces.
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.
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 reduce 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.
Add-on hardware modules and accessories for analog and digital cards.
The S400M FXS module allows 800 Series or 2400 Series analog cards to terminate four (4) analog stations per module. The X400M FXO module allows 800 Series or 2400 Series analog cards to terminate four (4) analog lines per module.
The S110M FXS module allows 400 Series or 800 Series analog cards to terminate a single analog station per module. The X100M FXO module allows 400 Series or 800 Series analog cards to terminate a single analog line per module.
FXS modules provide ringing voltage and battery to telephones or handsets and require substantial amount of 12V DC power in order to operate properly. The PCI interface on motherboards cannot provide sufficient quantities of this voltage necessary to ring 4, 8 or 24 modules.
