OpenVox B400E ISDN BRI PCI-Express

OpenVox B400E ISDN BRI PCI-Express

SKU: B400E

Product Overview
The OpenVox B400E is a half length ISDN (Integrated Services Digital Network) BRI (Basic Rate Interface) PCI-Express card. The B400E provides four ISDN BRI S/T ports, which makes it an ideal cost effective option for small to medium sized enterprise applications. OpenVox are a Fonality® Authorized / Certified Ecosystem (FACE) partner and the OpenVox B400E is officially certified for use with Trixbox®.

The B400E supports both TE (Terminal Equipment) and powered NT (Network Terminating) modes. The B400E provides functionality similar to ISDN BRI cards from alternative vendors such as the Digium® B410P, Junghanns® duoBRI and beroNet® BNXS0.

Standard PC (Personal Computer) hardware can be used along with B400E cards to provide a low cost migration path from legacy ISDN PBXs towards an Open Source IP PBX based solution. The B400E is compatible with leading open source IP PBX software such as Asterisk®, Trixbox®, and Elastix® (OpenVox are an Elastix® Strategic partner), which support all the sophisticated features of expensive high-end PBX/Voicemail platforms. Although developed primarily for Open Source IP PBX Asterisk® based applications, the B400E can be used for any Linux applications/systems that require ISDN connectivity, e.g. Linux ISDN firewalls, VoIP gateways and routers.

Feature Summary
On board first-in first-out (FIFO) static random-access memory (SRAM) buffers for hardware based channel switching
Built in Dual-tone multi-frequency (DTMF) detection machine for hardware based DTMF detection
Onboard multi network terminating (NT) power feeding circuit (most vendors provide this as an optional extra)
Built in conference bridge unit which allows up to 8 conferences with an arbitrary number of members each
Onboard parallel processor interface hardware watchdog for detecting Miscellaneous interrupt conditions
Four ISDN BRI ports: 2 B channels (e.g. for two separate voice channels) and 1 D channel for signalling per port
High quality components: The OpenVox B400E uses an ISDN controller chip from the same manufacturer (Cologne) used by Digium, Junghanns and beroNet for their ISDN cards
Terminal Equipment (TE) mode: Receives a clock from the BRI interface to connect to a device operating in Network Termination (NT) mode, e.g. PBX line card or ISDN network provider NT1 unit
Network Termination (NT) mode: Sources a clock to the BRI interface for connecting to a device operating in Terminal Equipment (TE) mode, e.g. PBX trunk card, router or ISDN telephone
Point-to-multipoint mode: Standard connection mode for private ISDN users and small business users to connect multiple ISDN devices
Point-to-point mode: Standard connection mode for business ISDN users for connecting a single ISDN device, e.g. PBX
Full hardware and software compatibility: Compatible with most well known brands of open source computer telephony equipment
Linux ISDN driver support
mISDN: Supports complete BRI ETSI compliant EuroISDN DSS1 Stack for NT and TE mode
BRIstuff: Set of patches and ISDN BRI drivers along with automated download and patching scripts for Asterisk, Zaptel and Libpri
isdn4bsd: ISDN driver for FreeBSD 5/6/7 and NetBSD 2/3, supports EuroISDN DSS1 (point to point and point to multipoint) in NT and TE mode
ISDN standards support
Net 3 ETSI EuroISDN (TBR3) attachment requirements for terminal equipment to connect to an ISDN using ISDN basic access
International Telecommunication Union Telecommunication Standardization Sector (ITU-T) I.430 Basic user-network interface - Layer 1 specification
European Telecommunications Standards Institute (ETSI) ETS 300 012-1 ISDN Basic User-Network Interface (UNI) Specification
