Abstract
A system for use in nodes communicating over a CPRI (common public radio interface) allows each networking node in a daisychain configuration to seamlessly manage the control and management HDLC (high-speed data link control) channel for both uplink and downlink. The connection is kept alive through a soft reset flow. Received HDLC packets can be extracted for use by a local node. Locally generated packets can be inserted into the packet data stream at the datalink layer for onward transmission over the CPRI. The system arbitrates between the locally generated packet data held in a buffer in the local node and remote packet data received from a remote node and held in the local node in a first in first out buffer for onward transmission to a subsequent node after arbitration. Remote packet data is given priority.
