TransferJet protocol layer basics
This page on TransferJet protocol stack covers basics of TransferJet protocol layers. The stack covers physical layer(PHY), Connection Layer(CNL), Protocol Conversion Layer(PCL) and application layer.
Figure depicts the TransferJet protocol stack layers.
PHY layer(Physical Layer):
This layer converts digital data information into an RF signal before being coupled with TransferJet couplers. Before RF, data is passed through various physical layer modules such as Convolutional encoder, RS encoder, spreading, scrambling and modulation. Read more
CNL layer(Connection Layer):
This layer manages both connection as well as data delivery. For connection management, it establishes, maintains and releases the connection with the peer device. For data management, it packs the data payload as per frame format and ascertain successful delivery of packets.
PCL layer(Protocol Conversion Layer):
It is responsible for converting packet of different application formats (such as SCSI/OBEX) into TransferJet protocol format.
The funtionality of this layer is same as OSI application layer, it provides human users, as well as other programs with carious services that use data communication. It supports OBEX/SCSI applications.
