Basic Concepts
The auxiliary interface board of the OptiX OSN equipment provides a 64 kbit/s synchronous data port (that is, F1 port). The auxiliary interface board uses the F1 byte to provide the client with a channel for transparently transmitting a point-to-point 64 kbit/s service.
The F1 data port is a codirectional port for transparently transmitting the 64 kbit/s point-to-point service. Only point-to-point services can be configured on the F1 data port and the point-to-multipoint broadcast data services cannot be configured on the F1 data port.
When the F1 data port is used, you need to configure the routes only, that is, you need to configure the 64 kbit/s services to be added to, dropped from, or passed through the local station. After the configuration is activated, the data transmission is performed.
The data is transparently transmitted. Hence, you need not configure the port rate and transmission control protocol.
