8 Follow "Procedure 1: Preconversion procedure," Software conversion
procedures (553-2001-320), and print configuration records.
Check the configuration record printouts to identify all configured I/O
ports. When you switch service to the Core/Network module, one I/O
address must be available for a CPSI port. Refer to Appendix B:
"Terminal and modem connections" on page B-1 for specific
information regarding the terminal and modem settings.
• If only one address is available, the CPSI port for a terminal
connection is automatically assigned to it.
• If more than one address is available, the CPSI port for a terminal
connection is automatically assigned to the first available address
(the lowest number). If more than one address is available, the I/O
port for a modem connection is also assigned automatically.
• If there is no address available, the device assigned to I/O address 15
is automatically replaced by the CPSI port for a terminal connection.
