ABSTRACT:
A terminal adapter for a telecommunication network having a receiver for multiple HDLC communication channels. The receiver includes a BCC calculator for computing and checking the validity of a received HDLC CNM frame. The terminal adapter further includes a device for detecting the reception of a specific CNM header included in a CNM frame on any of the HDLC communication channels and responsive to the detection for setting the BCC calculator to a predefined state. The latter state corresponds to the state of the BCC calculator after a computation of BCC for the specific CNM header. Therefore the BCC calculator can proceed with computation of said BCC for the CNM frame.
