6.3 Part of ISDN connections

To Connect of PBX to telecommunication network we have to have an ISDN access (BRI

or PRI), and installed one or more ISDN cards in the machine. It is depend on traffic what we

going to offer. For connection to telecommunication network we can use both active and

passive ISDN cards with or without CAPI (Common ISDN Application interface). ISDN cards

operated with the i4l (isdn4linux) driver.

Tab. 16 -Summary of ISDN cards supported by the kernel's ISDN driver

Note:

Note that there is an alternative method to use ISDN hardware within Asterisk that employs the

CAPI channel driver (chan_capi); however this channel driver is not part of the standard

Asterisk code distribution. Most analog modems provide half-duplex only, and Asterisk doesn't

provide a simple path to integrate those into the system.
