3 — Cabinets, Carriers, and Circuit Packs
This section describes the cabinets, carriers, and circuit packs, their functions, physical 
specifications, and interconnections in DEFINITY ECS R8. It also describes minimum 
cabinet and carrier configurations relative to interconnection and system-duplication 
options.
NOTE:
To determine required types and numbers of cabinets, carriers, circuit packs, or 
adjuncts before installation, contact your Lucent Technologies representative.
Cabinets
This section describes the auxiliary, Processor Port Network (PPN), Expansion Port 
Network (EPN), and AC-power cabinets.
A Multi-Carrier Cabinet (MCC) can be used as a PPN cabinet and/or an EPN cabinet. 
Doors on the front and rear of the MCC protect the internal equipment and allow easy 
access to the circuit packs. Each cabinet contains casters. Leveling feet keep the cabinet 
from rolling. Each corner of a cabinet can bolt to the floor, if required. See Figure 30.
The DEFINITY csi model uses the Compact Modular Cabinet (CMC).
The DEFINITY si model uses the Single-Carrier Cabinet (SCC) or the MCC.
The DEFINITY r model uses the Multi-Carrier Cabinet for the PPN and uses either the 
MCC or the SCC for the EPNs.

AUX Connector Capacity
The AUX (auxiliary) connector is on the rear of the control carrier. Up to 3 attendant 
consoles or telephone adjuncts can be powered by the AUX connector in the A position in 
the MCC and the SCC cabinets. Only 1 attendant console connects to the R8csi 
cabinets.
Up to 3 emergency transfer panels can be powered by the AUX connector in the A 
position in DEFINITY cabinets. Only 1 emergency transfer panel connects to csi cabinets.

75 Cabinets 
Auxiliary Cabinet (J58886N)
The Auxiliary Cabinet contains the hardware to install optional equipment. The cabinet 
allows carrier, rack (width: 23 in.; 58.4 cm), and panel types of mounting. An Auxiliary 
Cabinet contains the following:
nFuse panel (J58889AB) distributes –48 VDC to fused cabinet circuits 
nAC-power receptacle strip provides switched and non-switched 120 VAC 
receptacles 
nDC connector block is required when the cabinet is powered by an external DC 
source, or an AC to DC power supply that converts AC-power provided by the AC 
power strip switched-outlet to the required DC-power
Processor Port Network Cabinet (J58890A)
A Processor Port Network (PPN) cabinet (see Figure 31) contains the following carriers:
nPort carrier (J58890BB) — 1 to 4 
nControl carrier (J58890AH) in R7si and later — 1 
nDuplicated control carrier (J58890AJ) R7si and later — 1 in high or critical reliability 
configurations 
nProcessor carrier (J58890AP) inR7r and later — 1 in all systems, 2 in high 
reliability and critical reliability systems
nSwitch Node (SN) (J58890SA) in R7r and later with a Center Stage Switch 
(CSS) — 1 in standard and high reliability systems or 2 in critical reliability systems
nIn a R7r and later with ATM, the ATM interface card would be placed in a port 
carrier.

An Expansion Port Network (EPN) cabinet (Figure 32) contains the following carriers:
nPort carrier (J58890BB) — 1 to 4 
nExpansion control carrier (J58890AF) — 1 
nSN Carrier (J58890SA) in CSS-connected R7r and later systems — 0, 1, or 2 when 
required

Figure 33. Dual EPN in an R7r or Later Multi-Carrier Cabinet
The above figure is for the configuration of a minimal Dual Expansion Port Network 
cabinet for the r model. The A, B, and C carriers are intended for the first port network in 
the cabinet. The D and E carriers are intended for the second port network in the cabinet.   
The first carrier of a second Port Network in the cabinet must reside in carrier E. The E 
carrier must be used when there is only one carrier in the second EPN in the cabinet.    
When a cabinet has two Port Networks, carrier E must be used and populated first and 
carrier D added and populated second.

Carriers in MCCs
The following types of carriers can install in MCCs:
nJ58890AH Control Carrier (si model) (J58890AH Control Carrier (si model)) 
located only in the R7si or later PPN cabinet. Contains SPE circuit packs to 
perform call processing, maintenance, and administration. These carriers also 
contain port circuit pack slots.
nDuplicated Control Carrier (si model) (J58890AJ) (optional), in R7si or later PPN 
only. Contains duplicate SPE circuit packs to perform call processing, 
maintenance, and administration identical to the Control Carrier. The Duplicated 
Control Carriers also contain port circuit pack slots. Only R7si/r or later support 
duplication (uses the R8r Control Carriers for duplication).
nProcessor Carrier (r model) (J58890AP), only in the R7r or later PPN cabinets. 
Contains SPE circuit packs to perform call processing, maintenance, and 
administration. These carriers do not contain port circuit pack slots. Two J58890AP 
carriers are in the PPN for high and critical reliability (duplicate processor) systems.
nJ58890BB Port Carrier (optional), located in the PPN and EPN cabinets. Contains 
port, service, and tone/clock circuit packs.
nExpansion Control Carrier (J58890AF), only in the EPN cabinets. Contains extra 
port circuit packs, tone-clock, maintenance interface, and EI circuit packs.
nSwitch Node Carrier (SN) (J58890SA) (optional), in R7r or later, in the PPN cabinet 
and/or EPN cabinets. Contains SNI circuit packs composing the CSS.

Carrier Circuit-Pack Slots
There are 3 types of circuit pack slots in the carriers: Control, Port, and Service.
NOTE:
The purple-colored and white-colored circuit packs and slots are being replaced 
by circuit packs and slots labeled with gray and white rectangles, respectively. A 
label with a solid gray rectangle indicates a port slot/circuit pack. A label with an 
outlined white rectangle indicates a control slot/circuit pack.
nPort: colored purple or labeled with a gray rectangle and can accept any purple or 
gray-labeled circuit pack
nControl: colored white or labeled with an outlined white rectangle and can accept 
only a circuit pack assigned to that slot
nService: colored purple or labeled with a gray rectangle; is a special type of circuit 
pack that does not have an I/O connector
Each port slot attaches to a 50-pin (25-pair) connector on the carrier’s rear panel. A cable 
attaches to each connector and routes to the cross-connect field. Each slot containing a 
fiber optic interface circuit pack (EI or SNI) uses a fiber optic transceiver on the carrier’s 
rear panel. 
A current limiter board (CFY1B) plugs into the backplane of the control carrier located in 
the 
A position only. The board supplies emergency transfer logic, current-limited power, 5 
VDC to trip the main circuit breaker in an over-temperature condition, and the ringing 
transfer relay. Terminators on the backplane terminate each end of the processor 
expansion bus.
The following apparatus blank faceplates (with widths) cover unused circuit pack slots in 
the carriers to maintain proper air flow: 
nZ100A1 (0.75 inches/1.9 cm)
nZ100C (0.5 inches/1.27 cm)
nZ100D (0.25 inches/0.64 cm)
NOTE:
Throughout this section, the power units and circuit packs shown in the front 
views of the carriers are representative examples only. Actual, installed hardware 
may vary from that shown.
