ACS-PRI/BRI Card Introduction
Figure 4-5 highlights the ability of the system to be able to set the protocol between network
side and user side for each D channel it uses. Since the PBX can only run the user side
protocol, the system must run the network side protocol on the D channel connected to the
PBX. However, on the D channels connected to the carrier switches, the system must run the
user side protocol.
