An inverse multiplexer differs from a demultiplexer in that each of the low rate links coming from it is related to the other Designs PMC-Sierra (Nasdaq:PMCS PMCS PMC Sierra (stock symbol) PMCS Project Management Control System PMCS partial mission-capable, supply (US DoD) PMCS Preventive Maintenance Checks & Services PMCS Professional Military Comptroller School ) today announced three Inverse Multiplexer for ATM (IMA (Interactive Multimedia Association, Annapolis, MD) An earlier trade association founded in 1988 originally as the Interactive Video Industry Association. It provided an open process for adopting existing technologies and was involved in subjects such as networked services, scripting ) products. The PM7341 S/UNI-IMA-84 supports an industry leading 84 T1 or 63 E1 links in a single device and is optimized for T1/E1 over fiber applications in Multiservice ATM switches, Metro-Optical Access switches and Third Generation (3G) Wireless Base Station Controllers. The PM7342 S/UNI-IMA-32 supports up to 32 links and is optimized for high density T1, E1 or ADSL See DSL. ADSL - Asymmetric Digital Subscriber Line over copper applications in DSL DSL in full Digital Subscriber Line Broadband digital communications connection that operates over standard copper telephone wires. It requires a DSL modem, which splits transmissions into two frequency bands: the lower frequencies for voice (ordinary Access Multiplexers (DSLAMs), Multiservice Access Multiplexers, and 3G Wireless Base Station Controllers. For low link count applications such as Integrated Access 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 3G Base Stations -- the PM7340 S/UNI-IMA-8 supports up to 8 T1, E1 or ADSL links. All three devices set a new benchmark for device density in their respective classes -- the S/UNI-IMA-84 replaces 10 or more devices using previously available solutions (see Figure 1). IMA Bridges the Bandwidth Gap between T1 and T3 Today service providers offer broad availability for 1.5 Mbit/s T1 services. The explosive demand for high data rate applications such as videoconferencing and LAN (Local Area Network) A communications network that serves users within a confined geographical area. The "clients" are the user's workstations typically running Windows, although Mac and Linux clients are also used. interconnect is driving the need for access speeds beyond 1.5 Mbit/s. Currently the next standardized service rate beyond T1 is 45 Mbit/s T3. T3 services are often more than 10 times the cost of T1, have limited availability When customers of the PSTN make telephone calls, they commonly make use of a telecommunications network called a switched-circuit network. In a switched-circuit network, devices known as switches are used to connect the caller to the callee. , and provide more bandwidth than many users require. IMA technology is designed to bridge the bandwidth gap between T1 and T3 by combining multiple low cost T1 lines into a single higher speed service at multiples of 1.5, 3, 4.5, 6 Mbit/s or higher. In addition to IMA over T1, the S/UNI-IMA family also supports multiplexing of E1 and ADSL links (see Figure 2). "We worked closely with PMC-Sierra on the definition of the S/UNI-IMA chip and the S/UNI-IMA software driver to ensure compliance to the stringent requirements for deployment by the major carriers," said Thomas Alex Hamilton

(NASDAQ: CSCO, HKSE: 4333 ) is an American multinational corporation with 54,000 employees and annual revenue of US $28.48 billion as of 2006. . "The combination of the S/UNI-IMA-84 and TEMUX-84 meets the port density, power and performance required by our next generation multiservice switches," continued Hamilton. S/UNI-IMA Further Strengthens Industry's Most Comprehensive Multiservice Offering These three new devices join PMC-Sierra's broad portfolio of high density multiservice access solutions which includes the SPECTRA(TM) SONET/SDH framers, TEMUX(TM) T1/E1 framers, AAL1gator(TM) circuit emulation processors, MECA MECA Maine College of Art MECA Middle East Children's Alliance MECA Manufacturers of Emission Controls Association (Washington, DC) MECA Marriage Equality California MECA Mars Environmental Compatibility Assessment (TM) Voice-over-Packet processors, FREEDM FREEDM Frame Engine and Data Link Manager (TM) HDLC (High-level Data Link Control) A data link protocol from ISO for point-to-point communications over serial links.
