Therefore, each port provides a connection for both the primary and the secondary rings. if the stored FCS and computed FCS values are not equal. Chapter 7 - Data Link Layer 50 7.3.5 The Frame ring2 Point-to-Point Protocol for WANs ring2 Point-to-Point Protocol (PPP) is a protocol used to deliver frames between two nodes. These devices include the network adapter or network interface cards. Note that Ethernet only detects in-transit corruption of. If the CRC value in the FCS differs from the CRC calculated at the receiving node. It allows the receiver to discover whether errors occurred in the frame. Frames are used to send payload data from a source to a destination. The FCS field is the only field present in the Ethernet trailer.

Each channel has two separate 8-bit data buses, one for the receiver and another for the transmitter. A frame check sequence (FCS) is an error-detecting code added to a frame in a communication protocol. These ports connect the DAS to the dual FDDI ring. CRC (Cyclic Redundancy Check) check with parameterizable FCS (Frame Check Sequence) length and arbitrary polynomials. Concentrators will be covered in more detail in the following discussion.Д®ach FDDI DAS has two ports, designated A and B.

One of the primary advantages of connecting devices with SAS attachments is that the devices will not have any effect on the FDDI ring if they are disconnected or powered off. FDDI defines four types of devices: single-attachment station (SAS), dual-attachment station (DAS), single-attached concentrator (SAC), and dual-attached concentrator (DAC).ДЄn SAS attaches to only one ring (the primary) through a concentrator. One of the unique characteristics of FDDI is that multiple ways actually exist by which to connect FDDI devices.
