J58890SA  Switch Node Carrier (SN) 
The Switch Node Carrier (SN) (J58890SA) is used in R8r and later only. See Figure 39 for 
a representative example. The SN can contain one or two switch node clocks, up to 16 
Switch Node Interface (SNI) circuit packs, 1 or 2 DS1 converter circuit packs, one EI 
circuit pack, and 2 AC or DC power units.
The AC or DC power units are located at each end of the SN. The SN always contains 3 
memory circuit packs and 1 packet interface circuit pack and can be used when 
connecting 3 or more EPNs. See Table 19 for the SN rear connector descriptions.

Single-Carrier Cabinets
This section describes the following types of Single-Carrier Cabinet (SCC):
nBasic Control Cabinet (si model) (J58890L)
nDuplicated Control Cabinet (J58890M)
nExpansion Control Cabinet (J58890N)
nPort Cabinet (J58890H)
nCompact Modular Cabinet (csi model) (J58890T)
nDC power distribution cabinet
Figure 40 shows a typical SCC. Each SCC has vertical slots that hold circuit packs. A 
blank faceplate covers each unused slot. 
NOTE:
Throughout this section, the power units shown in the front views of the carriers 
are examples only.

A maximum of 4 SCCs can stack on top of each other. The cabinet positions are labeled 
A through D. The position of the basic control cabinet or expansion control cabinet is 
always labeled A. Additional port cabinet positions are labeled B, C, and D, sequentially. 
The Duplicated Control Cabinet is labeled B. See Figure 41.

Figure 41. Typical SCC Stack
Each stack of SCCs requires 1 basic- or Expansion-Control Cabinet at the bottom of the 
stack. Three is the maximum number of port cabinets per stack.
Cabinet clips connect the cabinets together. At the rear of the cabinets, a ground plate 
connects between cabinets for ground integrity. Chapter 2, ‘‘Site Requirements’’, 
describes the power and ground requirements for SCCs.

Carrier Circuit Pack Slots
There are 3 primary types of circuit pack slots in the carriers: 
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 in a port carrier, an expansion control carrier, and a control carrier in R7si 
or later attaches to a 25-pair connector on the carrier’s rear panel. A cable attaches to 
each connector and routes to the cross-connect field.
Blank faceplates cover empty carrier slots, as follows:
n158J (4 in/9.2 cm) covers the area left of slot 1 in port cabinets 
n158P (0.75 in/1.9 cm) covers any unused slot.
n158N (0.50 in/1.27 cm) is used with the DEFINITY LAN gateway in DEFINITY 
AUDIX R3 and CallVisor ASAI installations. 
n158G (0.25 in/0.63 cm) is used with the TN755B or TN2202.
NOTE:
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.

J58890L  Basic Control Cabinet (si model)
The Basic Control Cabinet is in the PPN only. It contains ports, a control complex to 
perform call processing, and an interface to an optional Duplicated Control Cabinet. It 
also interfaces to the optional STRATUM 3 Clock. See Figure 42 for an example.
The Basic Control Cabinet has dedicated white circuit pack slots that house specific 
control circuit packs. Also see Table 20. Dual-colored slots may contain any port circuit 
pack or the designated white circuit packs (such as an expansion interface or power unit). 
AC or DC power units supply power to the carrier.

J58890M  Duplicated Control Cabinet 
The Duplicated Control Cabinet is optional and is only in the PPN in R7si or later. See 
Figure 43 for a representative example. This cabinet contains ports, a duplicated control 
complex, and an interface to a designated expansion control cabinet.
The Duplicated Control Cabinet has dedicated white circuit pack slots for designated 
control circuit packs. The port circuit pack slots can contain any port circuit packs.
An AC or DC power supply, at the right side of the cabinet, supplies power to the cabinet. 
The cabinet contains a duplication interface circuit pack in slot DUPN INTFC. See Table 
21 for the Duplicated Control Cabinet rear connector descriptions.
Table 20.Basic Control Cabinet (si model) (J58890L) Connectors
Connector Function
1 to 16 (A1 to A16) 25-pair connectors connect port circuit packs to the 
cross-connect field or a fiber transceiver.
AUX (auxiliary) Provides interfaces for customer alarms, attendant console 
power, emergency power-transfer panels, and an internal 
modem (for remote maintenance)
PI (processor interface)  Provides a BX.25 protocol interface for communication 
between the circuit pack and external DCE equipment. This 
connection is only used with the standard reliability option. 
DCE  Connects the processor to CDR equipment, a system printer, 
or an external modem (for remote maintenance)
TERM (terminal) Connects an administration terminal to the processor circuit 
pack in standard reliability systems. Can be used to access 
the standby SPE. The TERM connector always connects to 
the processor in its own carrier.
DOT (duplication option 
terminal)Used in high reliability and critical reliability systems to 
connect an administration terminal to the active processor via 
the duplication interface slot. The DOT connector can be used 
to connect to the processor in another carrier.
