Terminal adapter having a multiple HDLC communication channels receiver for processing control network management frames. |
摘要 |
<p>A Terminal adapter for a telecommunication network having a receiver (400) for multiple HDLC communication channels. The receiver includes a BCC calculator (460) for computing and checking the validity of a received HDLC CNM frame. The terminal adapter further includes means (340, 350, 360) for detecting the reception of a specific CNM header included into a CNM frame on anyone of said HDLC communication channels and means (394, 530/X) responsive to said detection for setting the BCC calculator (460) to a predefined state. The latter state corresponds to the state of the BCC calculator (460) after a computation of BCC for the specific CNM header. Therefore the BCC calculator (460) can proceeds with computation of said BCC for said CNM frame.</p> |
