What options are available for the Pro? Q45. What is the ID number? Q46. What is the CTI bus? ************************** Q44. What options are available for the Pro? Options inlcude the Telephone Management System, the Interactive Video Information System and the Realtime Interface. For more information, see: http://starfish.rcsri.org/rcs/pdp-11/Professional/Handbook - Michael Umbricht mikeu@osfn.org Q45. What is the ID number? Each Pro has a 47-bit Identification number stored in ROM. This is not the same as the serial number printed on the case label. Some software (for instance VENIX) is keyed to this number. To view the ID use Maintenance Services and choose Configuration Display. The top line shows: Identification number: ############ - Michael Umbricht mikeu@osfn.org ************************** Q46. What is the CTI bus? The Pro system bus is called the CTI, or Computing Terminals Interconnect bus. It has 22-bit addressing (4Mbytes) and multiplexes addresses and data, combining 16-bit data signals with the 22-bit address signals on 22 signal lines. In most cases, the bus will allow option modules to be placed in any available option slot. Each option module can generate two different hardware interrupt signals. The option modules feature zero-insertion force connectors. When an option is in place, an option-present signal is asserted. Each option contains onboard ROM with identification information. - Michael Umbricht mikeu@osfn.org ************************** End of part IV: DEC Professional Computer FAQ.
