The BSV interface works in Usermode when connecting to an ISDN network, or works in Network mode when connecting to TEdevices such as the digital telephones or the BSV interfaces working in User mode.Choose the cable connection type according to the operating mode:• When the BSV interface works in User mode, choose the connection method according to thetype of the cable provided by the service provider:{ If the service provider provides an ISDN U interface cable, you must use an NT1 device foradaptation. Connect one end of the standard ISDN S/T interface cable to the RJ-45interface of the BSV interface module. Connect the other end of the standard ISDN S/Tinterface cable to the S/T interface of the NT1 device. Connect the ISDN U interface cable tothe U interface on the NT1 device.
