In the following illustrations, a balanced ring generator (BRG) is shown below the 
power unit slot in certain carriers. This means the power unit slot can include a 50 
Hz BRG when optioned for France.

DEFINITY Enterprise Communications Server Release 8.2
System Description  555-233-200  Issue 1
April 2000
This carrier has dedicated white-colored circuit pack slots that always contain specific 
control circuit packs. Dual-color slots may contain any port circuit pack or the designated 
white circuit packs (such as an EI or power unit). AC or DC power units supply power to 
the carrier. Table 14 describes the connectors on the rear of the control carrier.
NOTE:
The TN776 is not shipped in the R7si and later systems. It can remain in the 
system if packet endpoints and the C-LAN (TN799) are not used.
.Table 14. Control-Carrier Connectors
Connector Function
1 to 9 (A1 to A9)  25-pair connectors provide interfaces between port circuit 
packs and the cross-connect field or fiber transceiver
AUX (Auxiliary) Interface for alarms, attendant console power, emergency 
power transfer panels, and an internal modem (for remote 
maintenance)
Processor interface 
(standard reliability 
only)Connects directly to the PI circuit pack. Provides a BX.25 
protocol interface for communication between the circuit pack 
and external DCE equipment.
Data communications 
equipmentConnects the processor to CDR equipment, a system printer, 
or an external modem (for remote maintenance). This 
connector can be used with any reliability option.
Terminal Connects a management terminal to the processor in 
standard reliability systems. In critical reliability systems, 
connects a terminal to the processor in its control carrier.
Duplication option 
terminalUsed in high and critical reliability systems to connect an 
administration terminal to the active processor from the 
duplication interface slot position
P1 Provides position indicator of the carrier, power to fans, and 
access to alarm and control circuits
P2 Provides control signals to the carrier

J58890AJ  Duplicated Control Carrier 
(si model)
The Duplicated Control Carrier (J58890AJ) has dedicated white circuit pack slots that 
always contain specific control circuit packs. It can also be populated with port circuit 
packs or dual-colored slots that may be populated with port circuit packs or designated 
white circuit packs (such as an expansion Interface or power unit).
AC or DC power units located at each end of the Duplicated Control Carrier supply power 
to the carrier. See Figure 35 for a representative example. See Table 15 for the 
Duplicated Control Carrier rear connector descriptions.

J58890AP  Processor Carrier (r model)
The Processor Carrier contains only dedicated slots for control circuit packs composing 
the Switch Processing Element (SPE). It does 
not contain port circuit pack slots. See 
Figure 36 for a representative example.
AC or DC power units located at each end of the Processor Carrier supply the power to 
the carrier. The Processor Carrier always contains 3 memory circuit packs and 1 packet 
interface circuit pack. See Table 16 for the Processor Carrier rear connector descriptions.
