The Hx8 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 Hx8 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 Hx8-series hybrid telephony cards can deliver a wide range of voice applications including IP PBX, VoIP Gateway, IVR platform, Conference Bridge, Voicemail, and more.

Hybrid Telephony Card

Like Digium's analog and single-port PRI cards, the Hx8 hybrid telephony cards utilize Digium's VoiceBus™ technology. VoiceBus technology allows the Hx8 cards to use an industry standard bus-mastering PCI interface to maximize system compatibility and eliminate system conflicts. Additionally, the Hx8 cards can eliminate troublesome echo with the optional VPMADT032 echo cancellation module.

The Hx8 Series are half-length, full-height hybrid telephony cards supporting Digium's single-port FXS (S110M) and FXO (X100M) modules as well as Digium's quad-port FXS (S400M) and FXO (X400M) modules and 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 Hx8 is available in universal 3.3/5.0V PCI format as HA8 and in PCI-Express x1 format as HB8.

Applications

  • Connect Asterisk applications to ISDN and / or analog phone service
  • Connect legacy analog and / or ISDN BRI PBX systems to VoIP services
  • Build small form-factor solutions with both analog and ISDN technologies
