Document Summary

Lan tech is not the same as wan. When connecting two lan technologies, you can use a wan technology. Need to make a conversion from wan to lan. Dsu (data service unit) converts to lan technology. T1 carrier has 24 channels, each channel has 64 kbps, therefore normal capacity is 1. 54 mbps. If you want to make a call from office to office, you can use one of the 24 channels. For medium, you can use twisted pair (stp/utp/fibre optic/microwave) Csu/dsu can be integrated with a router, can be pushed into the slot of a router. Smart jack monitors signal for errors to guarantee quality of service. When smart jack finds errors in network, it reports error, and sends information to service provider. If there are errors, the service provider will know and can take action to ensure quality services. On ethernet card, when light is green, no error.
