These three phases take place when we make a phone call. Circuit establishment takes place when we dial up a number. At that moment, the public network attempts to establish a connection to the phone set that we dialed. This involves finding a path to the called party, allocating a channel on each transmission link on the path, and alerting the called party. The data transfer phase follows, during which we converse with the person we called. Finally, the circuit disconnect phase takes place when we hang up.
The payload of each frame is exactly 1500 bytes. e. the HDLC header and trailer). 6. In the DS-1 format, what is the control signal data rate for each voice channel? 7. 25, why is the virtual-circuit number used by one DTE of two communicating DTEs different from the virtual-number used by the other DTE? After all, it is the same full-duplex virtual circuit! 32 BASIC CONCEPTS FROM COMPUTER NETWORKS 8. Make-up an arbitrary IP header and calculate its checksum. e. flip single bits) so that the checksum when calculated by the receiver will fail to detect that the IP header has been received in error.
The unacknowledged connectionless service is supported using the unnumbered information PDU, and the acknowledged connectionless service is supported using two new unnumbered PDUs. 13. The LLC header contains the following fields. I/G is a 1-bit field indicating whether the destination address is an individual address or a group address. DSAP and SSAP are 7-bit fields indicating the destination and source Service Access Points (SAP). C/R is a 1-bit field indicating whether the frame is a command or response frame.
