The BPX 8600 BNI-T3 card set only supports the STI interface format. The primary clock source should be set to the BNM-T3, which is shown as Inband from BNM . BNC Verify the cell framing and payload scrambling settings on the T3 line. The payload scrambling setting must match that of the BPX 8600 BNI-T3. Payload scrambling was developed to ensure that ATM cell payload does not resemble a cell header.
Payload scrambling is only significant locally.
Specifically, each side of an ATM interface must have the same payload scrambling value, but all ATM interfaces in the network do not require the same configuration. Configuration settings that are different than those of the local feeder are provided below. Verify cell framing and payload scrambling parameters on the DS3. The settings must match those on the remote BNM-T3, which resides on the same MGX 8220. The primary clock source is configured for the DS1.
