white-colored circuit packs. A label with gray indicates a slot for a port circuit pack. A label with
white indicates a slot for a control circuit pack.
A 25-pair connector on the rear panel of the carrier connects to each port slot in the following
carriers:
● a port carrier

Basic control cabinet for a DEFINITY Server SI
The basic control cabinet is in the PPN only and is used only by DEFINITY Server SI. This
cabinet contains ports, a control complex to perform call processing, and an interface to an
optional duplicated control cabinet. The basic control cabinet also interfaces to an optional
Stratum-3 clock.
The basic control cabinet has dedicated white-colored slots that contain specific control circuit
packs. Dual-colored slots can contain any port circuit pack or a designated white circuit pack,
such as a power unit like the TN755 or TN2202. AC or DC input power supplies provide power
to the carrier. The following figure shows an example of the basic control cabinet.
