PMC-Sierra Introduces Industry's First Quad ATM PHY Chip; S/UNI-MPH Provides High Density T1/E1 ATM Inverse Multiplex and UNI Solutions for Edge and Enterprise ATM Switches.VANCOUVER, British Columbia--(BUSINESS WIRE)--Sept. 27, 1995-- PMC-Sierra, Inc. today announced the introduction of the first Quad ATM Physical Layer (PHY See physical layer and physical. ) interface chip, the PM7344-RI S/UNI-MPH (MPH stands for Multi-PHy). This new addition to the S/UNI family of ATM physical layer devices allows designers to provide T1/E1 ATM interface solutions with at least three times higher density than currently available alternatives while significantly lowering the cost per channel. Primary applications for the S/UNI-MPH are in ATM enterprise switches and ATM central office edge switches. The S/UNI-MPH supports both individual T1/E1 ATM User Network Interface (UNI) connections as well as the emerging ATM Inverse Multiplexing T1/E1 interface currently being defined by the ATM Forum A membership organization founded in 1991 to promote ATM networking technology. It worked with ANSI and the ITU to set standards. Its first specification in 1992 defined the User-Network Interface (UNI). In 2004, the Forum merged with the MPLS and Frame Relay Alliance. . PMC-Sierra plans to continue working closely with other key inverse multiplexing proponents at the ATM Forum to complete the specification. The S/UNI-MPH is now available and packaged in a rectangular 128 pin 14x20 mm PQFP (Plastic Quad Flat Package) Refers to many varieties of QFP chip packages, which are molded in plastic. See QFP. . The device will be fully tested in PMC-Sierra's broadband conformance lab for adherence to ATM Forum, ITU (International Telecommunication Union, Geneva, Switzerland, www.itu.ch) A telecommunications standards body that is under the auspices of the United Nations. Comprising more than 185 member countries, the ITU sets standards for global telecom networks. and Bellcore standards. Pricing for the PM7344-RI S/UNI-MPH is $125 in high volumes. Key features of the S/UNI-MPH include integrated quad T1 and quad E1 framers, T1/E1 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. datalink processing, a quad ATM cell processor, and an 8 bit, 25 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. , Utopia compliant ATM-PHY Layer cell interface. The S/UNI-MPH is also software compatible with PMC-Sierra's industry standard PM7345 S/UNI-PDH for DS-3, E3, T1 and E1 UNI applications, with the PM4341A T1XC T1 Framer/Transceiver, the PM6341 E1XC E1 Framer/Transceiver and with the PM4344 TQUAD Quad T1 Framer. "The combination of the extensive ATM system level expertise within the SATURN Group combined with PMC-Sierra's extensive ATM PHY layer design and verification expertise delivers a terrific `one-two punch one-two punch n. 1. A combination of two blows delivered in rapid succession in boxing, especially a left lead followed by a right cross. 2. Informal An especially forceful or effective combination or sequence of two things. ,'" said PMC-Sierra's vice president of marketing and business development, Steve Perna. "We reviewed the final specification for the chip at our May SATURN meeting and the response was very positive. A number of SATURN members have designs underway and have placed orders," Perna added. "The S/UNI-MPH solution allows designers to implement large numbers of T1/E1 channels on ATM enterprise or edge switch port cars and it is tailor-made to address T1/E1 ATM Inverse Multiplex applications," said Glenn Bindley, marketing manager for WAN products at PMC-Sierra. "Port card density is critical with these products because the switch cost per port is a key metric in the end users' equipment selection decision." PMC-Sierra, a wholly-owned subsidiary of Sierra Semiconductor, is a leader in networking component solutions emphasizing broadband ATM, SONET/SDH and T1/E1 applications.
