A telephone system such as small business telephone systems are connection oriented system. These system connects an internal phones of an organization. It also provides connection to different devices such as faxes, PSTN, modems, computers, extensions, etc.

They can be both. E.g. MPLS-TP or Connection-Oriented-Ethernet (COE) are connection oriented.

Connection-Oriented means that when devices communicate, they perform handshaking to set up an end-to-end connection. Connection-Oriented systems can only work in bi-directional communications environments. Connection-less means that no effort is made to set up a dedicated end-to-end connection. Walkie-talkies, or Citizens Band radios are a good examples of connection-less communication.
Connection oriented is more reliable because there is an acknowledgment received from data receiver (destination) that the data is receiving and transfer is successful which is not received from connection less protocol.
In connection oriented network first is confirmation of establishment of connection then only communication can take place while in connection less without establishment confirmation the communication start up.
Different from a connectionless protocol, a connection-oriented protocol guaranties the delivery of the information. An example of connection-oriented protocol is (TCP) and a connectionless protocol is (UDP). page/926 A+
Transmission Control Protocol (TCP) is used when data reliability is needed since it is connection oriented and guarantees delivery.
Different from a connectionless protocol, a connection-oriented protocol guaranties the delivery of the information. An example of connection-oriented protocol is (TCP) and a connectionless protocol is (UDP). TCP is a connection-oriented protocol, it makes a connection and checks whether the data is received, and resends if it is not. UDP is a connectionless protocol, it does not guarantee delivery by first connecting and checking whether data is received.
TCP is known as a connection-oriented protocol, which means that a connection is established and maintained until such time as the message or messages to be exchanged by the application programs at each end have been exchanged.that connection is virtual only...
