Bit rate interface is another name for basic rate interface, or BRI. BRI is used in ISDN configurations for voice-grade telephone operations.
To configure the clock rate for the hardware connections on serial interfaces such as network interface modules (NIMs) and interface processors to an acceptable bit rate, use the clock rate interface configuration command. Use the no form of this command to remove the clock rate if you change the interface from a DCE to a DTE device. Using the no form of this command on a DCE interface sets the clock rate to the hardware-dependent default value.

It stands for Basic Rate Interface. In the Integrated Services Digital Network (ISDN), there are two levels of service: the Basic Rate Interface (BRI), intended for the home and small enterprise, and the Primary Rate Interface (PRI), for larger users.
A basic rate interface is an ISDN subscriber line which provides two B channels and one D channel.

When the interface is functioning as a DCE device
The interface is configured as a DCE device.
Primary rate interface
It can do both. In order to use VoIP you have to get a PRI card, which cost used about US$699 (model no. RPTU PRI).
