Page 14: System Terminal Access For Cs 1000E
System terminal access for CS 1000E Terminal Server Because each CS 1000E Core Call Server provides only two ports for serial devices, the Terminal Server is used to provide the necessary standard serial ports for the applications and devices that require them (for example, for printers and Call Detail Recording [CDR]).
Page 15 Remote access telephone line system terminal With the CS 1000E, a system terminal can also connect directly to the Call Server, Signaling Server, Media Cards, and Media Gateway 1000Es (MG 1000Es). When a system terminal is installed directly on the Call Server, it connects to the Com 1 port.
Page 16: System Terminal Access For Mg 1000T
Page 16 of 162 Communicating with the system System terminal access for MG 1000T When a system terminal is installed locally with an MG 1000T, it connects to to the SSC card on the MG 1000T Core through a rear SDI port. The NTBK48 three-port cable can be connected to the SDI port to provide a total of three serial connections.

The maintenance port on the Shielded 50-pin to Serial/ELAN/TLAN Adapter provides an alternative to the faceplate maintenance port. For details, see the Voice Gateway Media Card installation in Communication Server 1000E: Installation and Configuration (553-3041-210). Additional Serial Ports...

They allow faulty equipment to be disabled to prepare for replacement. After the faulty equipment is replaced, the new equipment can then be tested and enabled. To perform system maintenance on the CS 1000E, use the following: • OTM Server or OTM Client PC using a graphics-based user interface that incorporates icons, pull-down menus and a mouse.

When the user accesses the system through a system terminal, a login procedure is required. If a sysload (system reload) occurs before the new password is saved in a data dump, the last active password remains valid.

Page 48: System Alarms
The causes of major alarms are listed in Table 7 on page When an MG 1000E is equipped with a power fail transfer unit (PFTU), a major alarm causes designated analog (500/2500-type) telephones to connect directly to Central Office trunks. This is called a line transfer.
