Exam 15: Wan Technology and Protocol

Which of the following is an advantage of circuit switching?

In a __________ network ,data entering the network from a station are routed to the destination by being switched from node to node.

Basic packet switching technology has recently been developed to replace circuit switching.

_________ signals are used for the maintenance,troubleshooting,and overall operation of the network.

Almost all wide area networks use circuit switching.

__________ allows users to plan for network expansion and modifications arising as their needs change.

________ signals identify a subscriber.

In a circuit switching network,the path that will be used through the network is determined prior to any data transfer.

Switching nodes are devices that enable data to be moved from senders to receivers.

The ________ is the link between the subscriber and the network,also referred to as the subscriber loop or local loop.

_______ are the devices that attach to the network.

The major application that uses circuit switching networks is the telephone system,thus most data transferred using this type of network is voice traffic.

Each station attaches to a node,and the collection of nodes is referred to as a ________ network

A public telecommunications network can be described using four generic architectural components: subscribers,subscriber line,exchanges,and _________.

Interconnection of computer systems is not reliable when using circuit switched networks.

Data communications via circuit switching involves three phases:

________ are the branches between exchanges.

With ________,the calling user (program or individual)supplies the phone number of a URI (Universal Resource Indicator,a form of URL),which then triggers a set of protocol interactions resulting in the placement of the call.

A public telecommunications network can be described using four generic components:

In circuit switching networks,channel capacity between each pair of stations and / or nodes along the connection path must be reserved regardless if used or not.
