Reply To: STM-1


thnks a lot guys, u were a great help..

Is the data on the STM-1 only transmitted fiber optic link, or by microwave as well..for example, in a BTS, microwave antenna is used to transmit E1 data. I have heard that microwave antenna can also be used to tranmit STM-1 data. Please calrify…furthermore, if microwave can be used as STM-1 link, how it differs from normal Abis-link (E1).
