Lucent Technologies New High-capacity Switch Accelerates Cost-effective Migration to Internet Protocol Networks.Business & Technology Editors MURRAY HILL Murray Hill may refer to one of the following places:
5E-XC(TM) switch based on significant 5ESS (1) (Electronic Switching System) A large-scale computer from Lucent used to route telephone calls in a telephone company office. The 5ESS is a Class 5 central office switch, and the 4ESS is a Class 4 tandem office switch. (R) switch enhancements that nearly triple capacity, offer path to IP networks, provide up to 50 percent operational savings and help increase revenue Lucent Technologies (NYSE NYSE See: New York Stock Exchange : LU) today introduced a new high- capacity switch and components to enable service providers to evolve their existing 5ESS(R) circuit switched networks to Internet Protocol See Internet and TCP/IP. (networking) Internet Protocol - (IP) The network layer for the TCP/IP protocol suite widely used on Ethernet networks, defined in STD 5, RFC 791. IP is a connectionless, best-effort packet switching protocol. networks. The new 5E-XC(TM) switch is part of Lucent's strategy to focus on near and clear market opportunities that play to the company's strengths - in this case circuit switching A networking technology that provides a temporary, but dedicated, connection between two stations no matter how many switching devices the data are routed through. Circuit switching was originally developed for the analog-based telephone system in order to guarantee steady, consistent and circuit-to-packet evolution. The high-capacity switch consists of the most significant upgrades to the 5ESS switch in the last 10 years and nearly triples the capacity while requiring considerably less floor space. A large service provider is deploying the high-capacity switch in its local network to interconnect (1) To attach one device to another. (2) A physical port (plug, socket) or wireless port (transmitter, receiver) used to attach one device to another. , primarily, with wireless and long distance carriers in an application known as an access tandem See tandem switch. switch. (See separate release today). The tandem (Tandem Computers Inc., Cupertino, CA) A former major manufacturer of fault-tolerant computers founded in 1974 by James Treybig and provider of the early 21st century technology for HP's enterprise computing strategy. application is the first in a series of 5E-XC switch applications. `The 5E-XC portfolio offers the most significant enhancements to the 5ESS switch in the last decade," said Dave Geary, vice president and general manager of Lucent Technologies Convergence Solutions business. "We are delivering what our customers want - a cost-effective migration to next-generation packet networks -- having higher capacity, higher densities, higher speed interfaces while reducing footprint, reducing power, and simplifying software delivery. Next-generation voice networks will evolve from current investments, will be IP-based, and will be enabled through SIP." Lucent's 5E-XC portfolio can deliver savings on service providers' operating and capital expenses. Savings are achieved by software, density and capacity improvements as well as access to more efficient IP transport networks and the addition of SIP (Session Initiation Protocol (protocol) Session Initiation Protocol - (SIP) A very simple text-based application-layer control protocol. It creates, modifies, and terminates sessions with one or more participants. Such sessions include Internet telephony and multimedia conferences. It is described in RFC 2543. ). SIP provides the ability to add new revenue services to the 5ESS switch, and it also provides a much more cost effective delivery mechanism for existing and future services. Migrating To IP With SIP The 5E-XC portfolio includes an enhancement that enables service providers to deploy IP-over-optical trunk connections by adding software and a packet card to the switch. In its development laboratory, Lucent has demonstrated to customers circuit-to-packet calls using the IP card on a 5E-XC solution.

Boosting Capacity, Reducing Wireline and Wireless Network Operating Expenses Operating expenses The amount paid for asset maintenance or the cost of doing business, excluding depreciation. Earnings are distributed after operating expenses are deducted. Providing up to 256,000 trunks, compared to 92,000 trunks on an existing 5ESS switch, the 5E-XC high-capacity tandem switch A telephone central office switch that links telco end offices together and does not connect to the customer directly. Also called a "Class 4 switch" or "TDM switch," a tandem switch is a computer that is specialized for TDM-based, circuit-switched telephone calls. can save customers up to 50 percent annually on the total cost of owning a switch including office space, power, cooling, installation, maintenance and software-upgrade costs. The improved switch integrates smoothly under the same network management system Lucent customers already have in their networks. The increased trunk capacity in the 5E-XC helps mobile network operators expand and upgrade their current mobile switching centers A switching center is a node in a telecommunications Circuit switching network which is connected to either another switching center and/or to end user devices. Switching centers are aware of other centers and possible routes between them such that on demand a center can establish (MSCs), reducing the cost associated with adding voice capacity to their network to meet increasing subscriber demand. Additionally, the ability to employ packet trunking See port aggregation. between MSCs will reduce the cost of transporting voice calls between key markets, offering substantial additional cost savings. Delivering Flexibility, Scalability and Savings Lucent's switch architecture offers flexibility and scalability, permitting customers to deploy a complete 5E-XC switch or use components to upgrade an existing 5ESS to provide the extra capabilities. The 5E-XC components available today include the: -- Communications module (CM3), combined with new software, that can enable nearly three-times previous switch capacity yet uses only one-twelfth the space, one-tenth the power and requires fewer spares than the previous version. -- Optical interface unit (OIU) that enables a 10-fold increase in the number of trunks per cabinet or rack, and can support a mix of traditional voice and IP traffic on the same shelf. The OIU cabinet handles nearly 120,000 trunks. -- Signaling platform (PSU) that uses 40 percent less power, supports larger call volumes and requires fewer spares than previous platform. -- Switch software (5E16.2) that can enable greater switch capacity, has a longer life, and also offers service providers additional call-forwarding, voice-mail, call-waiting and call-transfer features to help customers increase market penetration and revenues. New features include call-forwarding to five different numbers simultaneously and a Centrex call transfer feature that identifies (via caller ID) the individual initiating the call rather than the individual transferring the call. The longer life software permits service providers to add features through software downloads instead of time-consuming and costly retrofits. This saves customers up to 75 percent in software retrofit costs. Additional information on 5E-XC solutions is available at http://www.lucent.com/5e-xc.
