Carriers
Circuit packs labeled with gray and white latches have replaced the purple-colored and the
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
● an expansion control carrier
● a control carrier
A cable attaches to each connector and routes to the cross-connect field.
The following blank faceplates cover empty carrier slots to ensure proper cooling:
● 158J (4 in/9.2 cm) covers the area to the left of slot 1 in port cabinets
● 158P (0.75 in/1.9 cm) covers any unused slot.
● 158N (0.50 in/1.27 cm) is used with the LAN Gateway in DEFINITY AUDIX Release 3 and
CallVisor ASAI installations.
● 158G (0.25 in/0.63 cm) is used with the TN755 or the TN2202 circuit pack.
This section describes the carriers that the SCC1 Media Gateway can use.
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.
