The menu path follows:

It is important to note that some features in the ISU 512 do not immediately take effect upon selection. This prevents unintentional reconfiguration of the ISU 512 during an active call. Items such as Leased/Dial line, SPID/LDN, and ISDN switch type, take effect only when the ISU 512 is powered up or the Ba- sic Rate interface is bounced (line broken and restored). Also, items such as Bit Rate, BONDING setup, and Call type take effect only at the beginning of a new call.
