Hi :) here is some info for you on DMS Switches for all you switch ninjas
out there :)

DMS-10 Carrier Class Switching System:

Low initial product cost and low operating costs make the DMS-10 a proven
life cycle leader that provides the fastest return on investment of any
switching system in its class. The DMS-10 delivers advanced features such
as Meridian Digital Centrex, integrated Digital Subscriber Line (xDSL)
services for internet access, Basic rate interface (BRI) and Primary Rate
Interface (PRI) ISDN services, Advanced Intelligent Network (AIN) services
and a wireless interface.

Designed for small to meduim applications, the DMS-10 fits the need for
competitive service providers requiring low-to-meduim line size voice and
data networking. A single DMS-10 can provide access to 320 ISDN PRI links
or more than 20,000 lines.

As your market penetration grows, large cluster configurations can extend
coverage to a wider area. For flexible service delivery to remote subscribers
the DMS-10 supports the full portfolio of Nortel Networks remote access
solutions, such as the Star Remote System, and the AccessNode and AccessNode
Express. In addition, the DMS-10 also supports the TR303 generic interface
which allow you to connect to non-Nortel remote devices.

DMS-10 is a key element in Nortel Networks powerful unified networks
solutions strategy that spans data and telephony. Unified networks enables
you to take advantage of your existing revenue generating infrastructure
while seamlessly adding data and internet optimized segments. This powerful
union of the time-tested and the leading edge-built on the highly economical
DMS-10 platform-puts you in an enviable competitive position.

DMS-100/200 Local Switching System:

The modular DMS-100 local switching system directly serves residential and
business subscribers with leading edge communication solutions. Hundreds of
local carriers around the world rely on this fully digital system to reliably
deliver superior local exchange end office capabilities for serving areas,
large metropolitan business districts, large corporations, and a variety of
other applications.

The same hardware and software components of the DMS-100 system can be used
for a high capacity toll center with optional leading edge operator and
directory services. This DMS-200 Access Tandem terminates trunks as a traffic
concentrator between local exchanges. DMS-200 system options include a large
tandem that supports as many as 112,000 trunks and the DMS-100/200 system,
the first integrated Local Exchange/Toll Center solution.

 BENEFITS:

  - The DMS-100 system's modular hardware and software design offers
    impressive versatility so lines, trunks, and features can be added
    easily and cost-effectively.
  - This flexible solution can grow to over 135,000 lines and extend
    revenue generating services to remotes in outlying areas as much as
    650 miles away.
  - With the industrys largest menu of service options, the DMS-100 system
    provides extensive residential and business services ranging from basic
    telephone service to megabit data access for all market segments.

DMS-250:

The DMS-250 SuperNode is a high capacity switching system designed to anchor
the networks of interexchange carriers. Through the advanced DMS SuperNode
processing architecture, state of the art hardware, optimized system software
and maximum processing capacity, the DMS-250 provides high-speed message
handling capacity to meet the most demanding voice and data communications
needs of today's long distance users.

The modular, scalable system architecture of the DMS-250 system allows
network providers to add processing capacity, memory capacity, trunk capacity
and services as they are needed. The DMS-250 can be configured to handle from
480 to 100,000 trunks depending on call configuration. Enhanced processors
additonal switching matrices, peripherals, and trunk cards can be added
without redesigning the system or interrupting service.

DMS-300:

The DMS-300 switching system processes worldwide telephone traffic for voice
data and video between national and international networks. Offering a full
suite of signaling capabilities, the DMS-300 enables public network carriers
to expand service portfolios and establish operations as full-service
providers of national and international communications.

The DMS-300 is part of our proven family of DMS public network switching
systems. DMS switching systems are used throughout the world by the leading
public network carriers, who count on Nortel Networks products to provide the
highest level of reliability. The DMS-300 architecture is designed to support
the sustained levels of traffic over multiple busy hour peaks which are
characteristic of international calling patterns. The DMS-300 incorporates a
redundant architecture design to provide non-blocking network features.

 BENEFITS:

  - The platform to build the sustainable competitive advantage essential
    for profitable growth.
  - The capability to increase revenue streams through value added services
  - The power to control costs through precise and timely management tools
  - The ability to position your company as a total telecommunications
    provider to your customers.

DMS-300/250 - Combined Long Distance and International Switch:

Designed as an international gateway switch, the DMS-300/250 system processes
worldwide telephony traffic between national and international networks. This
large-capacity digital switching system is capable of supporting up to 70,000
trunks on a highly reliable, robust and versatile gateway platform.

Features:

Providers can drive down the costs and expand the revenue opportunities of
their networks through a combined DMS-300/250 system. With a single software
load on the same DMS hardware platform, providers can deliver the long
distance features of the DMS-250 switch along with the gateway features of
the DMS-300 - sharing common DMS Maintenance and Administration Position
(MAP) interfaces and tables.

 BENEFITS:

  - Reduced costs through sharing of switching equipment
  - Reduced operations, administration, maintenance, and provisioning (OAM&P)
    expenses through equipment and training efficiencies.
  - Additional revenues with the combined, expanded feature set.
  - Modular, scalable architecture meets a wide range of trunk size
    requirements.
  - Flexibility in service development and differentiation.
  - Standards-compliant platform interworks with network switching and
    transmission equipment, including different versions of ISDN, supplied
    by a variety of vendors.

DMS-500 - Local and Long Distance Switch:

The DMS-500 Local and Long Distance Switch is a DMS SuperNode application
that combines local services of the DMS-100 switch, toll and operator
services of the DMS-100/200 Traffic Operator Position System (TOPS), and long
distance services of the DMS-250 switch. In addition to the trunk connections
supported by the DMS-250, the DMS-500 delivers all line types currently
supported by the DMS-100 system for residential and business applications.

The DMS-500 is a total solution with one of the industry's most application
rich portfolios of carrier services loaded with major capabilities that are
market-ready today. These include local services, long distance services,
call center services, operator services, and data services. And, as part of
the Nortel Networks Succession network plan, the DMS-500 is uniquely
positioned for the evolution to data-centric communications.

     - selling or reselling long distance services.
     - operating with or without operator services.
     - offering business and residential line services.
  - Cost and operational efficiencies gained in combining DMS-100/200 and
    DMS-250 services:
     - reducing front-end hardware requirements
     - reducing office site and environmental requirements
     - centralizing operations, administration, maintenance, and provisioning
  - Expanded pre  and post sales service support to build a network, train
    the staff, and operate the network, if needed.
  - Multi-vendor network operability ensured with the DMS-500 Supernode
    system's open architecture.

Thats all folks. Cya Next time :)
