Basic Rate Interfaces (BRIs) and Primary Rate Interfaces (PRIs). Remote 
Common Application Programming Interface (RCAPI) is the CAPI feature 
configured remotely from a PC client. CAPI provides the following features:
A standardized interface...

Supported B Channel Protocols
When the router receives packets destined for one of the DCP clients on its BRI 
port, the router formats the packet as a DCP message and sends it to the 
corresponding client. The router supports all of the DCP messages in the 
ISDN-DCP specifications defined by RVS-COM.
Supported B Channel Protocols
The router provides two 64-kbps B channels to CAPI clients. Each B channel...

Tones for NET3 Switch
By default, the Cisco 800 series routers are configured so that the telephone 
switch supplies tones, such as dial, ringback, and busy tones. However, NET3 
switches, which are used in Europe, do not provide these tones. You can use the 
pots tone-source local command from global configuration mode to configure
