Networking Issues
This is an excerpt from the paper...
A limited distance modem (LDM), or short-haul modem, is employed in environments wherein data transmission distances are relatively short (one-to-seven miles) but where conditions exist that create risks for data integrity during transmission. A factory environment, as an example, would require relatively short transmission distances for a network. This environment, however, could subject network devices to a wide range of temperatures and to power surges. LDMs provide necessary environmental protections and support multi-drop communications architecture typically used in polled networks. LDMs permit computers, controllers, and terminals, and other devices with RS-232 or RS-435 ports communicate effectively while protecting these devices from ground loops and electrical and environmental hazards typically found in factory environments.A break out box (BOB) is a small device that attaches between two other devices that typically are connected by a cable, i.e., a computer and a modem. The function of the break out box is to display and, if desired, facilitate a change of the activity through individual wires of the cable connecting the two devices. A break out box would be appropriate for use in a hostile transmission environment wherein data communications between two devices could be subjected to interference. With a break out box installed, network administrators or technicians could identify transmissio

effective site participation in the planned network? This information is required to determine what personnel additions and retraining will be required. [10]
= Is the information infrastructure at each of the existing remote sites capable of functioning effectively in the planned network? This information is required to determine what equipment additions and upgrades will be required. [11]
= Are the information personnel at each of the existing remote sites capable of providing effective site participation in the planned network? This information is required to determine what personnel additions and retraining will be required. [12]
= How intensive will the traffic between existing remote sites be? This information is required to determine where networking capacity should be sited? [13]
= How is the intensity of traffic between existing remote sites expected to change over the near-term? This information also is required to determine where networking capacity should be sited? [14]
= What types of information will be transmitted over the planned network, and what will be the traffic volume of each information type? This information is required to assure that adequate bandwidth is incorporated into the network design. [15
