The Berofix card series is a powerful and flexible hardware solution to connect ISDN (BRI,PRI) and GSM lines to any SIP based VoIP system. The Berofix is not a Gateway and it is not a standard PCI/PCIexpress card where you have to install any drivers, therefore we call it a “Gateway card”. Due to the special design of the hardware berofix will be detected as a standard Realtek-Network card by the operating system. Usualy the driver for this network card will be loaded automatically by the OS. The only thing you have to do is to set up the IP-address before you can access the web interface which is very easy to use. The berofix card series has a modular concept and supports the following hardware DSP based Voice-Processing features:

• G.168/G.165 Echo cancellation with echo path change detection, up to 128ms
• Codec translation: G.723.1 and Annex A, G.729a, G.726, G.711u/a
• DTMF detection and generation
• T.38 fax relay (V.27,V.29 and V.17)
• SIP over TCP with SRTP and TLS
• DSS1, EuroISDN conform
• Q.SIG Basic-Features
• PCM Bus interconnection between berofix cards to enable hardware bridging for transparent voice, data and fax transmissions via optional PCM-Bus cable.

The Berofix card series consist of a baseboard and the so called LineInterfaces.

The following Lineinterfaces are available and can be plugged on the berofix card series.

• BF4S0, 4 Port BRI module
• BF1E1, 1 Port PRI module
• BF2E1, 2 Port PRI module
• BF1GSM,1 Port GSM module
• BF2GSM,2 Port GSM module

This card can handle 16-64 voice channels (2 modules BNBF1E1 or 1 module BNBF2E1).

Additionally to the baseboard and the LineInterfaces the following accessories are available for the berofix card series:

• bf4S0Bridge (to use all 4 RJ45 slots on a baseboard with one bf4S0)
• bnTAdapters (to connect 2 BRI Lines on 14 RJ45 slots)
• bnPCM Cable (to interconnect berofix baseboards)
• bnE1Crosscable (to connect berofix E1 ports to other systems)

Due to the modular concept you can mix PRI,BRI and GSM ports on one card with full above mentioned features which makes the berofix cards very unique.
