OPTIONAL FEATURES11-6 Edition One XC1000 Service11.4 MULTIPLE TERMINAL ACCESS (MTA)An optional version of MTA was designed before the ACP. The optional ACPsupersedes this version of MTA. MTA allows up to seven terminals toaccess maintenance and administration menus simultaneously from asingle XC1000. MTA comprises the MTA PC, the MTA port box (throughwhich administrator terminals and XC1000 are connected), and thesoftware on both the XC1000 and the MTA PC that supports the MTAfeature.The XC1000 software locks certain menus during the time that they arebeing used by one administrator. For example, while one administrator isadding or changing port parameters in menu 4, the other administratorscan only view the currently saved version of menu 4. This locking mecha-nism prevents other administrators from changing the same information atthe same time. XC1000 software also limits access to certain menus byMTA port. Terminals connected to MTA ports 1, 5, and 6 have access to allsystem-manager and service-utility menus. Terminals connected to MTAports 2, 3, and 7 have access only to system-manager menus 8, 9, and 10.A terminal connected to MTA port 4 has access only to system-managermenus 8, 9, 10, and 13.Port 1 on the MTA port box provides remote service access for OctelCommunications personnel. All XC1000 maintenance should be done froma terminal connected to this port. Ports 2 through 4 support 1200-baudterminals or 1200-baud modems for remotely located terminals. Ports 5through 7 support 9600-baud terminals or 9600-baud modems for remotely-located terminals. MTA port 8 is reserved for connecting the MTA to theJ50 connector on the XC1000 distribution board.Figure 11-3 shows an example of an MTA configuration. For detailedinformation about the MTA and installation procedures, refer to InstallationInstruction 181–1036–001.11.5 BUSY-OUT CONTROLLERThe Busy-Out Controller makes a group of ports busy. With the Busy-OutController, if a line or port is out of service, such as during maintenance,callers bypass the busy ports and are answered on an available port within ahunt group. If all ports within a hunt group are occupied when calls comesin, callers hear a busy signal rather than a ring-no-answer indication.The Busy-Out Controller supports analog connectivity only. Analog connec-tivity requires make-busy cable pairs between the XC1000 and the switchto make a busy condition on control ports or groups of ports. Theactivation of the controller requires manual control to initiate make-busyrequests. The Busy-Out Controller is available with the hot-plug softwarefeature for TICs and DLCs (Release 1.5). The Busy-Out Controller onlysupports ATICs and DID TICs.SECTION 11.4 – 11.5
