System considerations

For CS 1000 4.5 and 5.0, in dual-processor systems, the 2 card slots

on the back of a CoreNet shelf supporting CP PII and CP PIV function

regardless of which CPU is active. On Release 5.0 only the CP PII and

CP PIV are supported. In Options 61C and 81C, CS 1000SG, and CS

1000MG, four NT8D41BB can be provisioned for a total of 16 SDI ports.

One port is used for power monitoring, leaving 15 for customer use.

Connector pin assignments

The RS-232-C signals for port 1 through port 4 are brought out on

connector J1 through J4 respectively. The pinouts for each port are

identical to those for each of the other three ports. Table 285 "Connectors

J1, J2, J3, and J4 pin assignments" (page 725) shows the pin assignment

that applies to each connector.
