Product Description

The Digium HB8  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.

The HB8 Series are versatile devices used for connecting to the PSTN. This is accomplished with analog lines connected to trunk (FXO) interfaces, analog handsets connected to station (FXS) interfaces, and digital lines connected to ISDN BRI interfaces. The HB8 cards supports all three types of connectivity on a single card through the use of Digium’s specialized telephony modules for FXO, FXS, and BRI. Used in conjunction with Asterisk®, the HB8 cards can deliver a wide range of voice applications including IP PBX, VoIP Gateway, IVR platform, Conference Bridge, Voicemail, and more.

Like Digium’s analog and single-port PRI cards, the HB8 cards utilize Digium’s VoiceBus™ technology. VoiceBus technology allows the HB8 cards to use an industry standard bus-mastering PCI interface, as found in millions of PCs worldwide, to maximize system compatibility and eliminate system conflicts. Additionally, the HB8 cards can improve voice quality in troublesome echo situations with its support for Digium’s G.168-compliant 128ms cancelling VPMADT032.

The HB8 cards are half-length, full-height cards supporting Digium’s existing single-port FXS (S110M) and FXO (X100M) modules as well as Digium’s existing quad-port FXS (S400M) and FXO (X400M) modules. New with the release of the HB8 cards is Digium’s B400M four-port EuroISDN S/T module. The B400M sets a new standard for BRI connectivity in the Asterisk market with its support for software-selectable mode (NT or TE) and line termination. The B400M requires no jumpers for operation, regardless of mode or termination.

The HB8 is available in universal PCI-Express format.

Notes

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. As a solution, Digium FXS capable cards are mounted with a 4-pin disk-drive or Molex connector on the base board. This connector must be supplied with an internal power connector from the system's power supply if FXS modules are in use. For systems without available internal 12V power connectors, the PWR2400B is the solution.
