111 Direct Connect Cabinet Configurations 
Standard Reliability Systems
Table 27 lists the required EI circuit pack slots, tone-clock circuit pack slots, maintenance 
circuit pack slots, and remaining port circuit pack slots in a standard reliability 
direct-connect system.
High Reliability Systems
High reliability is available on R8si/r and later. Table 28 lists the required EI circuit pack, 
tone-clock circuit pack slots, maintenance circuit pack slots, and remaining port circuit 
pack slots in a high reliability, direct connect system. In the first cabinet, the EI circuit pack 
is not required in a single PN (PPN only) system because no connection to another 
cabinet is required.

Critical Reliability Systems (R8si/r and later) 
(Category A only)
Critical reliability is available on R8si/r and later. Table 29 lists the required EI circuit pack 
slots, tone-clock circuit pack slots, and remaining port circuit pack slots in critical 
reliability, direct connect systems. The Port Carrier in cabinet 1 is optional in systems with 
only 1 PN, but it is required in systems with 2 or 3 PNs. 
No EI circuit packs are required for systems with only a PPN because no connection is 
required to another cabinet. The EI circuit packs shown in cabinet 1 are shown in their 
R8r and later positions. These are installed in the control carriers in cabinet 1.
.
Cabinet Configurations in 
CSS-Connected Systems
In this type of system, a Lucent Center Stage Switch serves as a network hub, reducing 
the complexity of the interconnections and making more port networks possible. CSS- 
connected systems support up to 44 PNs.
Standard Reliability Systems
Table 30 lists configurations for a low-traffic, standard-reliability CSS system with up to 3 
Switch Node Carriers (SNCs) and up to 44 PNs. Standard reliability systems with 1 SNC 
can contain up to 2 DS1 converter circuit packs in the SNC. Standard reliability systems 
can only contain 1 maintenance circuit pack. 
In most cases, the maximum number of PNs has to be less than the theoretical number 
given in the tables to allow for additional connections between SNCs.

NOTE:
The information provided in Table 30 also applies to ATM-connected 
systems, with two exceptions. The number of switch node carriers for all 
port networks in an ATM-connected system is 0, and the expansion 
interfaces become ATM interfaces. Because the ATM-connected system 
does not use switch node carriers, there may be additional slots available 
in the switch.

NOTE:
The information provided in Table 31 also applies to ATM-connected 
systems (Category A only), with two exceptions. The number of switch 
node carriers for all port networks in an ATM-connected system is 0, and 
the expansion interfaces become ATM interfaces. Because the

additional slots available in the switch.
Critical Reliability Systems (Category A only)
Table 32 lists configurations for a low traffic, critical reliability CSS-connected system with 
up to 44 port networks (PNs). Critical reliability systems have a duplicated Switch Node 
Carrier (SNC). Up to 4 DS1 converter circuit packs can be installed, up to 2 per SNC. 
Critical reliability systems can contain up to 42 maintenance circuit packs.
In most cases, the maximum number of PNs has to be less than the theoretical number 
given in the tables to allow for additional connections between SNCs.

NOTE:
The information provided in Ta b l e  3 2 also applies to ATM-connected

Ta b l e  3 2 also applies to ATM network duplication.
Cabling to On- and Off-Premises

Cabling to On- and Off-Premises 
Systems
Cabling from the system to on-premises and off-premises systems establishes 
communications paths between the system’s line port circuits and trunk port circuits to 
external trunks, lines, and DTE equipment. The cabling from the system routes to the 
following:
nThrough the network interface to off-premises trunks and lines going to the Central 
Office (CO) and remote equipment
nPremises (house) wiring (data lines) going to information outlets (modular jacks) 
used for DTE and on-premises station sets
Cross-connect fields are termination points for equipment cabling and distribution 
cabling. Connections are made between those termination points to establish 
communications paths throughout the system. Two major types of distribution frames are:
nThe cross-connect field is the field on which terminations and cross-connections for 
CO trunks, equipment cabling, and distribution cabling are made.
nThe Intermediate Distribution Frame (IDF) is any cross-connect field between the 
main cross-connect field and the endpoint workstations. The terminations and 
cross-connections are made for the distribution cabling from the cross-connect 
field, from other IDFs, and from the site wiring from information outlets.
Circuit Packs and Related Hardware
This section describes the circuit packs and related hardware in DEFINITY Systems. The 
circuit packs are listed by apparatus code in Table 34. After the table, the circuit packs 
and their functions are provided.
All circuit packs are approximately 8 in. (20 cm) by 13 in. (33 cm). The following 
connectors attach to 1 end of a circuit pack: 200-pin connector to a 
TN-labeled circuit 
pack and a 300-pin connector to a 
UN-labeled circuit pack. 
Faceplates on the circuit packs are sized to fill the width of a slot, typically 0.75 inches 
(1.9 cm). Each circuit pack faceplate has a standard pattern of 3 LEDs that indicate the 
following conditions:
nRed indicates a fault condition
nGreen indicates a test condition
nYellow indicates a busy condition
