3.1  Definitions  p. 10

For the purposes of the present document, the terms and definitions given in TR 21.905, TS 23.501 , TS 23.502 and TS 23.503 apply. A term defined in TS 23.501, TS 23.502 or TS 23.503 takes precedence over the definition of the same term, if any, in any other specifications.
RG Level Wireline Access Characteristics:
Wireline access technology specific QoS information corresponding to a specific wireline access subscription, which is provided by the AMF to the W-AGF at RG registration.
Wireline access Control Plane protocol (W-CP):
Protocol used to transport AS and NAS signalling between the 5G-RG and the W-AGF over the Y4 reference point. W-CP is specified by BBF and CableLabs. There is no assumption that W-CP refers to only a single protocol or only a specific protocol layer.
Wireline access User Plane protocol (W-UP):
Protocol used to carry PDU Session user plane traffic between the 5G-RG and the W-AGF over the Y4 reference point. W-UP is specified by BBF and CableLabs. There is no assumption that W-UP refers to only a single protocol or only a specific protocol layer.
Legacy Wireline access Control Plane protocol (L-W-CP):
L-W-CP is a legacy control plane protocol between the FN-RG and W-AGF. L-W-CP is specified by BBF and CableLabs. There is no assumption that L-W-CP refers to only a single protocol or only a specific protocol layer.
Legacy Wireline access User Plane protocol (L-W-UP):
L-W-UP is a legacy user plane protocol between the FN-RG and W-AGF. W-UP is specified by BBF and CableLabs. There is no assumption that L-W-UP refers to only a single protocol or only a specific protocol layer.
Authenticable Non-3GPP (AUN3) device:
A device that does not support NAS signalling, is connected to 5GC via a RG and can be authenticated by 5GC over the RG.
5GS specifications do not support a device using the same subscription to access 5GS as a UE and as an AUN3 device.
Non-Authenticable Non-3GPP (NAUN3) device:
A device that does not support NAS signalling, is connected to 5GC via a RG and for which authentication with 5GC is not supported.
