PMC-Sierra Introduces Industry's First Eight Channel E1 Framer for High Density Internet and Telecom Access Equipment.VANCOUVER, B.C.--(BUSINESS WIRE)--May 4, 1998-- The 3.3 Volt PM6388 EOCTL Device Complies with the Latest ITU-T See ITU. ITU-T - International Telecommunications Union V5 Standards and Offers an Unparalleled Increase in System Density to Minimize Design Effort And System Cost PMC-Sierra, Inc., today announced the PM6388 EOCTL, the industry's first single-chip eight-channel E1 framer.(a) The device provides at least double the E1 framer density compared to previously available solutions. The EOCTL is the first multi-channel E1 framer device to use a low power 3.3 volt CMOS (Complementary Metal Oxide Semiconductor) Pronounced "c-moss." The most widely used integrated circuit design. It is found in almost every electronic product from handheld devices to mainframes. technology. As a result, the EOCTL achieves a typical power consumption of only 50mW per framer. Manufacturers of central office switches, digital loop carriers and Internet access See how to access the Internet. equipment can greatly increase system port density by using the EOCTL to reduce overall board space and power consumption by up to 50 per cent. A comprehensive EOCTL applications solution package including a hardware reference design, software drivers, datasheets, and a technical overview is available on PMC-Sierra's web site (http://www.pmc-sierra.com) to minimize design time and development resources. The EOCTL is available in June 1998, packaged in a 14 by 20mm 128 pin PQFP (Plastic Quad Flat Package) Refers to many varieties of QFP chip packages, which are molded in plastic. See QFP. , characterized to the industrial temperature range (-40 to +85 degrees Celsius) and priced at $86 in 1 KU quantities. EOCTL is the industry's first device to fully support a multi-channel V5.2 interface for E1(a) as specified by the ITU-T G.964 standard. This standard allows network operators to deploy products from multiple vendors in their access networks while ensuring interoperability. V5.2 standard compliance is now required for most of the world's telecom infrastructure including central office switches, digital loop carriers, wireless local loop systems and PBX (Private Branch eXchange) An inhouse telephone switching system that interconnects telephone extensions to each other as well as to the outside telephone network (PSTN). systems. The EOCTL integrates the three HDLC (High-level Data Link Control) A data link protocol from ISO for point-to-point communications over serial links. Derived from IBM's SDLC protocol, HDLC has been the basis for numerous protocols including X.25, ISDN, T1, SS7, GSM, CDPD, PPP and others. controllers per channel, each with 128-byte transmit and receive buffers, as required by the V5.2 standard -- for a total of 24 embedded controllers. EOCTL provides the industry's highest density solution for the aggregation of large numbers of E1 Internet and Frame Relay access lines(a. The device is pin and software-compatible with the PM4388 TOCTL (octal A numbering system that uses eight digits. It is used as a shorthand method for representing binary characters that use six-bits. Each three bits (half a character) is converted into a single octal digit. Okta is Greek for 8. T1 framer) enabling a common design platform for both T1 and E1 applications. EOCTL and TOCTL also connect directly to the PM7364 FREEDM-32 and PM7366 FREEDM-8 high density HDLC controllers for a complete frame relay or Internet access solution. In addition, EOCTL provides a 32 bit fully programmable Psuedo-Random Binary Sequence (PRBS PRBS Pseudo-Random Binary Sequence PRBS Pseudo Random Bit Sequence PRBS Pseudorandom Bit Stream (Hekimian) PRBS Probability Random Bit Sequence PRBS Pseudo Random Bit Stream ) generator and detector for each E1 framer. The PRBS function enables the Internet or frame relay service provider to conduct line testing and verification during service installation and enables ongoing line quality monitoring. "We worked closely with PMC-Sierra to ensure that the EOCTL would provide the density and reduced power consumption required for our next generation Internet See Internet2. Access products," said Leo Paquette, manager of hardware engineering at Bay Networks. "The availability of the pin-compatible TOCTL for T1 applications significantly reduced our overall design effort," concluded Paquette. "The EOCTL is designed to work seamlessly with PMC-Sierra's family of high density network access products including the PM4314 QDSX quad line interface unit and the PM4351 COMET single channel T1/E1 framer and line interface unit," said Glenn Bindley, PMC-Sierra's director of product marketing. "In addition, we ensured software compatibility with our previous generation E1XC single-channel and EQUAD quad-channel framer devices to maximize our customers' software investment and minimize overall time to market."
