Digium HB8 Hybrid Analog BRI PCI Express Card
The Digium 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 Digium HB8 Series 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 Digium HB8 series cards can deliver a wide range of voice applications including IP PBX, VoIP Gateway, IVR platform, Conference Bridge, Voicemail, and more.
Target Applications
- VoIP Gateways
- SMB Phone Systems
- Analog/Digital Converters
- PC-based PBX
Like Digium's analog and single-port PRI cards, the Digium HB8 cards utilize Digium's VoiceBus technology. VoiceBus technology allows the Digium HB8 cards to use an industry standard bus-mastering PCI Express interface, as found in millions of PCs worldwide, to maximize system compatibility and eliminate system conflicts. Additionally, the Digium HB8 cards can improve voice quality in troublesome echo situations with its support for Digium's G.168-compliant 128ms cancelling VPMADT032.
The Digium HB8 Series 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 Digium 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 Digium HB8 is available in universal PCI-Express x1 format as HB8.
