which provides a central processor to drive H.323 and Session Initiation
Protocol (SIP) signaling for IP Phones and IP Peer Networking.
Small Systems support global software as well as any IP cards.
The memory architecture of the system has program and data stored
in physically separate memory components: flash ROM and DRAM,
respectively. The majority of system and customer-configured data is both
controlled and stored on the SSC card’s flash ROM. The DRAM stores and
processes temporary automated routines and user-programmed commands.
Two flash drives on the SSC card perform software operations and store
customer data:
• The primary flash drive contains system data as well as the first copy of
customer data that must exist to load and run the switch. The primary
flash drive is programmed with system software before it is shipped
to the customer.
•
The backup flash drive stores modifiable files containing data such as
configuration data, or a second copy of the customer database. If the
primary flash drive fails, you can retrieve a backup set of customer data
to load into the system’s active database.
There are four areas on the SSC card where customer data records can be
stored:
•
DRAM — stores and accesses the active version of customer records,
system data, and overlay data. Data from the primary flash drive
overwrites data in DRAM storage during a SYSLOAD (system reload).
•
Primary flash drive (C:) — contains two copies of customer records
(primary and backup records).
•
Backup flash drive (Z:) — retains the true backup copy of the customer
database.
•
PC Card slot (A: or B:) — allows a complete copy of the customer
database to be stored on a Software Delivery card (PC Card) inserted
into this slot. The customer database on the PC Card can then be
removed for storage away from the SSC card.

SSC card and components
The NTDK20 SSC card controls call processing, stores system and
customer data, and provides various expansion interfaces. It includes the
following components and features:
•
flash daughterboard memory, DRAM, and backup memory
•
two expansion daughterboard interfaces
•
PC Card socket
•
three Serial Data Interface (SDI) ports
• 32 channels of Conferencing (64 if two single-port expansion
daughterboards are present, or 96 if two dual-port expansion
daughterboards are present)
•
10 Mbps network interface
•
30 channels of Tone and Digit Switch (TDS) and a combination of eight
Digitone Receivers (DTR) or Dial Tone Detectors (DTD)
•
Networking and Peripheral Signaling
•
additional tone service ports (four units of MFC/MFE/MFK5/MFK6/MFR
or eight DTR/XTD units)
Memory, processing, and data storage 23
The SSC card requires a Software Daughterboard in order to function. The
Software Daughterboard can be ordered preprogrammed with system
software and customer data.
A security device is required on the SSC card of the Main and all
Expansions. The security device, which remains on the SSC card for the
life of the system, is used for system identification. This device allows the
activation of features assigned to the system, through the use of a series of
keycodes. The system uses keycodes for validation purposes.
Signaling Server
CS 1000M Small Systems use a Signaling Server. The Signaling Server is
an industry-standard, PC-based server that provides a central processor
to drive H.323 and SIP signaling for IP Phones and IP Peer Networking. It
provides signaling interfaces to the IP network using software components
that operate on the VxWorks™ real-time operating system.
The Signaling Server has both an ELAN and TLAN network interface. The
Signaling Server communicates with the Call Server through an ELAN
subnet.
The Signaling Server is mounted in a 19-inch rack. The Signaling Server
can be installed in a load-sharing redundant configuration for higher
scalability and reliability.

Nortel Communication Server 1000
NN43011-110 01.01 Standard
Release 5.0 30 May 2007
24 Description and features
The following software components operate on the Signaling Server:
•
"Terminal Proxy Server" (page 24) (TPS)
•
"SIP/H.323 Signaling Gateways" (page 24)
•
"Network Routing Service" (page 25) (NRS)
•
"Element Manager" (page 25)
All the software elements can coexist on one Signaling Server or reside
individually on separate Signaling Servers, depending on traffic and
redundancy requirements for each element.
For more information about H.323 and SIP Trunking, refer to IP Peer
Networking: Installation and Configuration (NN43001-313) .
Terminal Proxy Server
The Terminal Proxy Server (TPS) acts as a signaling gateway between
the IP Phones and the Call Server using the UNIStim protocol. The TPS
performs the following functions:
•
converts the IP Phone UNIStim messages into messages the Call
Server can interpret
•
allows IP Phones to access telephony features provided by the Call
Server
The TPS also controls the IP Phone registration.
SIP/H.323 Signaling Gateways
SIP/H.323 Signaling Gateways are software components configured on
virtual loops, similar to IP Phones. SIP/H.323 Signaling Gateways bridge
existing call processing features and the IP network. SIP/H.323 Signaling
Gateways also enable access to the routing and features in the MCDN
feature set.
Note 1: The SIP/H.323 Signaling Gateway must register with the
Network Routing Service (NRS).
Note 2: Virtual TNs enable you to configure service data without
hardwiring IP Phones to the CS 1000S system. Virtual TNs are
configured in LD 97.
To support IP Peer Networking, dual Call Servers in a CS 1000M Small
System must be associated with Signaling Servers that run SIP/H.323
Signaling Gateway software. The number of Signaling Servers required
depends on the capacity and level of redundancy required.

Network Routing Service
The Network Routing Service (NRS) application provides network-based
routing, combining the following into a single application:
•
H.323 Gatekeeper — The H.323 Gatekeeper provides central dialing
plan management and routing for H.323-based endpoints and gateways.
•
SIP Redirect Server — The SIP Redirect Server provides central dialing
plan management and routing for SIP-based endpoints and gateways.
•
NRS Database — The NRS Database stores the central dialing plan in
XML format for both the SIP Redirect Server and the H.323 Gatekeeper.
The SIP Redirect Server and H.323 Gatekeeper both access this
common endpoint and gateway database.
•
Network Connect Server (NCS) — The NCS is used only for Media
Gateway 1000B (MG 1000B) and Virtual Office solutions.
•
NRS Manager web interface — The NRS provides its own web
interface to configure the SIP Redirect Server, the H.323 Gatekeeper,
and the NCS.
The NRS application provides routing services to both H.323- and
SIP-compliant devices. The H.323 Gatekeeper can be configured to support
H.323 routing services, while the SIP Redirect Server can be configured to
support SIP routing services. The H.323 Gatekeeper and the SIP Redirect
Server can reside on the same Signaling Server.
Each system in an IP Peer network must register to the NRS. The NRS
software identifies the IP addresses of systems based on the network-wide
numbering plan. NRS registration eliminates the need for manual
configuration of IP addresses and numbering plan information at every site.
Element Manager
Element Manager is a simple and user-friendly web-based interface that
supports a broad range of system management tasks, including:
•
configuration and maintenance of IP Peer and IP telephony features
•
configuration and maintenance of traditional routes and trunks
•
configuration and maintenance of numbering plans
•
configuration of Call Server data blocks (such as configuration data,
customer data, Common Equipment data, D-channels)
•
maintenance commands, system status inquiries, backup and restore
functions
•
software download, patch download, patch activation

The Signaling Server for a CS 1000M Small System is installed separately.
Refer to Signaling Server: Installation and Configuration (NN43001-312)
for more information.
The Software Installation Program is automatically invoked during first-time
installation of the system. This menu-driven program installs the software
and makes the system operational.
Preprogrammed data
When you first install the system, you must enter customer data into the
overlay programs. For example, you must assign features to telephone keys
in order for those features to function correctly. Data can be preprogrammed.
If you load preprogrammed data during the installation process, the system
automatically configures some overlay entries on the telephones.
If the preprogrammed data does not apply to users at one site, you can
revise the data on-site with a TTY. You can also revise the preprogrammed
data remotely over a modem connection. You can start with a basic
configuration, which is the least possible amount of data required for initial
software programming. You must perform this step while you are working in
the Software Installation Program.
Installation and configuration 27
Model telephones
Small Systems offer a variety of preprogrammed model telephone layouts.
By using these telephone layouts (which serve as templates), technicians
can perform a few simple steps at installation to activate multiple telephones.
Administration telephone
If you use the default model layouts for telephones and trunk routes,you can
use an administrative telephone to make adjustments to items such as the
numbering plan and access codes. You do not need a TTY input terminal to
program a Small System unless a custom layout is used.
You can use a digital telephone for administrative functions. The
administrative telephone can double as a user’s working telephone.
Changing or removing preprogrammed data
If preprogrammed data does not apply to users at a particular site, data
can be revised on-site with a TTY or remotely over a modem connection.
If desired, the user can start with the minimal amount of data required for
initial software programming, which is the configuration record. This step
must be performed while the user is in the Software Installation Program.

Meridian Mail
Meridian Mail comes preconfigured with preprogrammed extensions for
mailboxes. If the numbering plan is being modified, then the mailboxes can
be changed from any TTY used for system administration.
Set-Based Administration
The Set-Based Administration feature simplifies system installation and
administration by enabling a telephone to perform several administrative
and maintenance procedures. Use the Set-Based Administration feature
to perform tasks such as changing data for specific features related to
telephones or changing Calling Party Name Display on a telephone.
For more information about Set-Based Administration, refer to Set-Based
Administration (NN43001-603).
Multiple-terminal access
Small Systems allow access to up to five users for logging in, loading, and
executing overlays simultaneously. For example, if you have Expansion
Cabinets, users can access the system through the Main or Expansion
Cabinets at the same time.
Three SDI ports are provided on the main SSC card, while each Expansion
can be accessed through the three SDI ports on the SSC card of each IP
Expansion or the single SDI port available on the Fiber Receiver card of
each Fiber Expansion.
The advantage of multiple-terminal access is that it allows for more efficient
programming and maintenance of the system, especially when system
components are located up to 3 km (1.8 mi) apart.
Database Archive feature
The Software Installation program allows the archiving of databases that
you can subsequently use to load a customer site. This feature allows
you to configure multiple databases in an off-site lab environment. The
Database Archive feature also allows you to save databases on a PC Card
until the databases are required. You can load the database into the system
using the PC Card.
The off-site programming of databases is subject to all security keycode
restrictions. The off-site system must either use the security device that will
be installed in the system at the customer site, or have its own keycodes for
the feature set.

The Small System as a branch office 31
Survivable IP expansion
IP Expansions can be configured to be survivable in the event of a link
failure or a catastrophic failure of the Main.
Based on the system configuration, if IP connectivity to the Main is lost or a
manual command is issued, an IP Expansion can enter survival mode, in
which it acts as a fully functional "stand-alone" system.
The number of survivable Expansions allowed on one system is controlled
through a software license called "Survivability", which has a range of 0–4.
The license default value is zero.
Voice distribution over a Campus Data Network
IP expansion connectivity provides a high-capacity, cost-effective solution
that can distribute Small Systems over a high-performance data network.
Full feature functionality and non-blocking architecture is maintained
when systems are distributed over high-performance data networks. This
patented solution delivers the exceptional functionality and reliability of
legacy systems, while delivering the benefits of voice and data convergence.
Packaging requirements
IP connectivity is provided by IP Expansion (IPEX) package 295. If the IP
Expansion package is restricted, IP connectivity between the Main and IP
Expansion is not allowed, whether or not IP daughterboards are connected
to the Main. CE-MUX expansion is not a separately packaged option, but
does depend on IP Expansion (IPEX) package 295.
The Small System as a branch office
The Branch Office feature extends Communication Server 1000 features
from a main office to one or more branch offices. The branch office connects
to the main office over Virtual Trunks on a LAN or a WAN.
A CS 1000M Small System can function as a main office.
With CS 1000 Release 4.5 software, customers can reconfigure existing
satellite Small Systems to function as branch offices to their main office IP
PBX. This configuration allows customers to incorporate systems that were
previously stand-alone into a Branch Office network. In this configuration,
the main office can be any CS 1000S system or CS 1000M Large System or
Small System operating CS 1000 Release 4.5 software. Any single-cabinet
or single-chassis Small System is eligible for conversion to a branch office.
For more information about the Branch Office feature, refer to Branch Office:

Cabinet and Chassis system mix-and-match expansion
In a mix-and-match scenario, a Chassis can be connected to IP Expansion
Cabinet(s). Similarly, a Main Cabinet can be connected to IP Expansion
Chassis.
Figure 11 "Cabinet and Chassis system IP expansion configuration" (page
43) shows an IP configuration in which a Main Cabinet is connected to an
Expansion Chassis using IP connectivity.

an SSC card equipped with an IP Expansion daughterboard. Slot 14 of
the Expansion contains the NTDK16 48-port Digital Line card.
Figure 12 "Cabinet and Chassis system IP and fiber expansion
configuration" (page 45) shows another example of a "mix-and-match"
configuration in which a Main Cabinet uses both fiber and IP cabling
to connect two Expansion Cabinets and one Expansion Chassis. The
Expansion Chassis is equipped with a Chassis Expander.
Note: Figure 12 "Cabinet and Chassis system IP and fiber expansion
configuration" (page 45) is only an example of one of many possible
configurations using Cabinets and Chassis.
In this example, the SSC card in the Main Cabinet has one dual-port
Fiber Expansion daughterboard installed in the top connector and one
single-port IP Expansion daughterboard installed in the bottom connector.
The dual-port Fiber Expansion daughterboard in the top connector supports
card slots 11–20 and 31–40. The single-port IP Expansion daughterboard
in the bottom connector supports card slots 21–30.
Note: When both Fiber and IP Expansion daughterboards co-exist in a
system, configure the Fiber Expansion daughterboard as expansions 1
and 3 and the IP Expansion daughterboard as expansions 2 and 4.
