The transceiver on slot 2, connector 1, does not have SQE (signal quality error)
enabled. It reports the absence of an SQE signal, even though it does not need it.

Data Path elects the circuit control gate for circuit 1. Each circuit must have a
circuit control gate.

Data Path registers the ISAP (internal services access point) for ARP. The protocol
type for ARP is 0806; this type determines that the ARP traffic will go to the
correct gate and code according to the Data Path. The number preceding the
protocol type indicates the packet format (1 = Ethernet type 2, 2 = 802.2,
3 = SNAP [Subnetwork Access Protocol] , 4 = Novell, and so on). Data Path
registers Ethernet Type II or SNAP ARP frames on circuit 1. In this example, Data
Path does not register the 802.2 ARP frame type. If circuit 1 received an 802.2
ARP frame, ARP would not receive it; instead, it would go to the Learning Bridge.

Data Path always registers Ethernet and SNAP frames for IP. In this example,
Data Path registers ISAPs on circuit 1 for the following protocols: IP (Ethernet
type 0800), IPX (Ethernet type 8137), and DECnet (Ethernet type 6003). The
number preceding the protocol indicates the packet format.
Notice how DECnet only registers one packet type, while two IPX packet types
are registered. This is because two unique IPX networks, each with a different
packet encapsulation type, are on circuit 1.
