Input/Output Controller
6. External Interface
As illustrated in Figure 2-29, the 68PH S 2PORTS CA-A cable is required to connect external equipment
such as the MAT, SMDR, MCI, and PRT.
Figure 2-29 External Cable Connection for PH-IO24 (IOC)
Securely insert the connector of the 68PH S 2PORTS CA-A into the appropriate MISC connector. Refer to the table listed below.
The relationship between the MISC connectors and the mounting
slot of the IOC (PH-IO24) circuit card is shown below.
The type of cables varies depending on a connected terminal and/or
whether modems are used or not. More detailed information on the
connecting cables is explained in the “Installation Procedure
Manual”.
