Basic Rate ISDN extension over fibre with the FRM2-BRI

The FRM2-BRI is a fibre optic modem for the transport of a basic rate ISDN service over fibre optic cabling. The unit is simple to configure with only a single DIP switch setting required. The following shows the configuration necessary to extend a basic rate ISDN service. This could be from British Telecom (ISDN2) or from a PBX or other ISDN equipment. The FRM2-BRI closest to the network is configured as a 'TE' and the corresponding unit closest to the end equipment is configured as a 'NT'.
