Recipient should accept the node provided as the new service provider. More precisely; the recipient should bind itself and the remainder of the layer it represents (its dataclients) to the layer supplied by the sender of TBindTo. TBindTo may be sent when processing TControlClient::TNoBearer or for other reasons (e.g.: building the layer or rebinding the layer during mobility scenarios). The sender of TBindTo should supply a startable layer, i.e.: as far as the sender is concerned the layer has a chance to start. For instance; if an SCPR receives TBindTo, then the sender CPR has started the connection, which means the SCPR's attempt to start its new service provider has a chance of succeeding.

The message provisions all the necessary information to configure the recipient. This is typically sent by a control provider to its freshly created dataclient. The message should contain all the data structures required by the recipient to function. For instance, an Ethernet flow should be provision with the static IP address info (if applicable).

Request to start the layer. The recipient should perform the 'start' routine pertaining to the technology/abstraction it represents. The recipient would usually send TStart to its dataclients in the course of implementing this request.

Sent to a dataclient to request permanent stop of the layer.
