For the deframer side, follow these steps: 1. Initialize and bring up the baseband processor framer side. 2. Deframer is held in reset state until INIT command, then deframer issues a synchronization request by asserting the SYNC signal.
3. Framer starts sending K28.5 characters, then deframer is brought out of reset. 4. Deframer identifies four consecutive K28.5 characters then deasserts SYNC and goes into ILAS phase. 5. If SYNC stays asserted, this indicates it is stuck in CGS phase. Check that the link parameters match. If they do, check the signal integrity (refer to the Sample Iron Python Code for PRBS Testing section). For the framer side, link establishment follows the same flow. First the framer is enabled and the baseband processor deframer
synchronizes to the signal.
