These new chips are ideal for network equipment such as DSLAMs, customer premise equipment (CPE (Customer Premises Equipment) Communications equipment that resides on the customer's premises. CPE - Customer Premises Equipment ) based routers, access multiplexers, and wireless base stations. The new PM5352 S/UNI(R)-STAR, PM7339 S/UNI(R)-CDB and PM7349 S/UNI(R)-4xD3F chips improve system design flexibility, speed time-to-market and reduce overall system cost for packet and ATM based networking equipment. Highly integrated silicon solutions are necessary to facilitate the expansion of service provider networks via DWDM (Dense WDM) The term given to wavelength division multiplexing (WDM) when significantly more channels were being added. Since WDM is increasingly more "dense" all the time, both terms are used synonymously. See WDM. DWDM - wavelength division multiplexing and SONET/SDH based transmission systems. In addition, interfaces into these networks require greater capacity and traffic handling capabilities. To facilitate this expansion, semiconductor solutions targeting customer premise equipment are migrating from T1/E1 rates to T3/E3 rates and those targeting DSLAM (DSL Access Multiplexor) A central office (CO) device for ADSL service that intermixes voice traffic and DSL traffic onto a customer's DSL line. It also separates incoming phone and data signals and directs them onto the appropriate carrier's network. See DSL. equipment from DS-3 to OC-3 uplinks. "While current system development efforts focus on OC-48, OC-192 and beyond, it is critical that we continue to enable our customers to design and build world-class multi-service equipment with T1/E1, T3/E3, and OC-3/STM-1 connections for today's multi-layered, multi-rate network," said Travis Karr, Product Manager, PMC-Sierra's Optical Networking Communications between computers, telephones and other electronic devices using light. An optical network is far more reliable and has far greater potential transmission capacity than networking in the electrical domain. See optical fiber. Division. New Solutions for DSLAM and Wireless Base Station Equipment The S/UNI-STAR is targeted at packet and ATM interfaces for applications such as DSLAM up-links (see figure 1), CPE based routers and switches and wireless base-stations. The device is a highly integrated single-channel OC-3 (155 Mbit/s) SONET/SDH framer that combines a dual-mode Packet-Over-SONET (POS (1) See point of sale and packet over SONET. (2) "Parent over shoulder." See digispeak. POS - point of sale ) frame processor and ATM cell processor with integrated clock recovery and clock synthesis. The S/UNI-STAR's jitter A flicker or fluctuation in a transmission signal or display image. The term is used in several ways, but it always refers to some offset of time and space from the norm. For example, in a network transmission, jitter would be a bit arriving either ahead or behind a standard clock cycle performance meets all Bellcore GR-253 intrinsic jitter, jitter tolerance and jitter transfer specifications. The S/UNI-STAR is also designed to be pin and software compatible with PMC-Sierra's PM5349 S/UNI-QUAD and PM5351 S/UNI-TETRA devices, preserving existing software investments and an easy migration path to four-channel devices. The S/UNI-4xD3F chip provides four physical layer interfaces for packet-based equipment, integrating four DS3 framers. Additionally, the device provides E3 and J2 framer support that can be independently configured with DS-3 for multi-service flexibility. By enabling a single board design to accommodate all three rates, the S/UNI-4xD3F greatly reduces design time for next-generation multi-service equipment, customer premise equipment routers and wireless base stations (see figure 2). The S/UNI-4xD3F is also designed to be pin and software compatible with PMC-Sierra's PM7347 S/UNI-JET and PM7346 S/UNI-QJET devices, preserving existing software investments. The S/UNI-CDB is a fully UTOPIA Utopia (y  tō`pēə) [Gr.,=no place], title of a book by Sir Thomas More, published in Latin in 1516. Level-2 standard compatible,
four-channel, cell delineation block device that can operate up to a
maximum speed of 52 Mbit/s. The device provides the Physical Layer
Convergence Protocol (PLCP PLCP Physical Layer Convergence Procedure (SONET)PLCP Planning Command Pool PLCP Physical Layer Conversion Protocol (DQDB, NEC) PLCP Premobilization Legal Counseling Program ) for DS-1, DS-3, E1 and E3 transmission systems. Support is provided for ATM direct mapping into various rates up to 52 Mbit/s. Targeted at quad-channel applications such as DSLAM Access equipment (see figure 3), Internet Access See how to access the Internet. Devices (IAD (Integrated Access Device) A device that multiplexes a variety of communications technologies in the customer's premises onto a single telephone line for transmission to the carrier. It also demultiplexes the incoming streams into their respective channels. ) and wireless base stations, the S/UNI-CDB provides the cell delineation needed in these ATM based applications. The S/UNI-CDB is also designed to be pin and software compatible with PMC-Sierra's PM7347 S/UNI-JET and PM7346 S/UNI-QJET devices, preserving existing software investments.
