Carrier Components

The carrier assembly is shipped with a power
transformer unit. Refer to Equipment List
Appendix D for details. Other carrier components are
ordered separately:
Power transformer unit. Provides low voltage
ac power to the carrier's internal power distribution
bus.
– 48 Vdc Central Office (CO) Power Unit. For
carriers designed to operate from a – 48 Vdc power
unit. Consists of a single dc power module with a
fan and operates in Basic mode. An optional second
power module is available for the CO Power Unit.
Fan module. Provides forced air cooling to
dissipate heat generated within the carrier. It is
recommended that fully configured carriers and
cabinets have fan modules installed to extend the
life of the equipment.
Shared Diagnostic Control Panel (SDCP).
Required for initial installation and testing of the
devices and their options. In conjunction with the
SDU, allows up to eight carriers to be managed
from one control panel.

dial, ISDN, or switched 56 kbps digital service
interface for DSUs, DBMs, and dial / lease modems.
Shared Diagnostic Unit (SDU). Provides the
required interface that daisy chains carriers together
for network management system (NMS) and /or
SDCP control. In a cabinet configuration,
connectivity between the units in the individual
slots allows control of compatible units in the
carrier. The control can be a single NMS interface,
a single SDCP, or both.
T1 auxiliary backplane(s). Provides an interface
between a T1 digital network and customer
provided equipment (CPE).
Rear connector plate(s). Provides the interface
between DSUs, DBMs, and dial / lease modems and
the DTEs.
Connector module(s). Provides the interface
between DSU/TDMs or DSU/MCMPs and the
DTEs.
Filler panel(s). Prevents accidental contact with
