Page 20: Network Media Installation - Local Line
Network Media Installation — Local Line Overview TIWAY I is a multi-drop communications network. It consists of a main trunk cable (the “spine”) and dropline cables. The network can connect up to 248 secondaries to a host computer. NOTE: Although addresses can range from 1 to 254 on TIWAY I, addresses 248 through 254 cannot be used because of the limitations of the Modbus protocol. -
Page 21: Tiway I Network Characteristics
TIWAY I Network The TIWAY I network cable consists of a main cable or spine with droplines Characteristics or taps for each secondary. The maximum main line cable length, cable type, tap length, tap spacing, number of secondaries, and maximum baud rates are interrelated network variables and have a direct influence upon network performance. -

Some disadvantages are the following. Is is impractical for buildings without drop ceilings Working in high ceilings can be hazardous Ceilings often collect dust and other debris Surface ducting — Surface ducting for network cabling is usually installed along the baseboards or is attached to walls at desktop height. While surface ducting ordinarily protects cables from both physical and EMI effects, it may also require that network computing devices be positioned near a wall. -
