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 320 "Connectors J1, J2, J3, and
J4 pin assignments" (page 825) shows the pin assignment that applies to
each connector.
