Description: When the physical and/or MAC layer has more than one PHY-connection or MAC-connection, this object is used to select the PHY- or MAC-connection to be bound to the PVC. The semantics of the value of this object is PHY and/or MAC specific. This semantics generally shall be specified with the PHY or MAC. However, the semantics for the two PHY/MAC specifications which have been identified as having multiple connections is provided here for convenience:

When the physical layer is dual latency ADSL, the PhyMacIdentifier selects the latency path to be bound to each direction of transmission for the PVC. The value of the PhyMacIdentifier shall be as follows: default = 0 upstream and downstream both interleaved path = 1 upstream and downstream both fast path = 2 upstream interleaved path, downstream fast path = 3 upstream fast path, downstream interleaved path = 4 The 'default' value shall be used for single latency ADSL PHYs.

When the physical and MAC layers are IEEE 802.14, the PhyMacIdentifier specifies the 802.14 Local Identifier for the PVC
