I/O connectors inside of the cabinet
Connectors on the inside of the cabinet bulkhead are designated J1 through
J9 as well as JX and JY on the daughterboard.
Connectors J1, J2, J3, and J6 each connect three active current loop ports
and one modem port to the external cabling by tracking through the
input/output panel and onboard EMI filters to the connectors on the other
side of the panel. These serial ports are cabled to the input/output panel
from the 68K transition module of an MSP or SPN.
Connector J4 connects four modem ports to the external cabling by tracking
through the input/output panel and onboard EMI filters to the connectors on
the other side of the panel. The modem ports are cabled to the input/output
panel from one of the TIFNs.
Connectors J7 and J8 are not used.
Connector J9 conveys the alarms and OA&M terminal switchover signal
from the Bus Controller transition module.
