Douglas Spencer received his B.S.E.E. (magna cum laude) from the University of Utah in 1968. He received his M.S.E.(E.E.) and (E.E.) Professional Degree in 1970 and 1972 respectively from the University of Michigan, where he studied under a National Science Foundation Fellowship. He joined AT&T Bell Labs in 1972 in the Transmission Terminals Laboratory where he worked on high speed transmission systems terminals (M34 Multiplexer: DS3 - 45 Mb/s to DS4 274 Mb/s). He turned up the M34 multiplexer for first service between Newark and New York City.
He transferred to the Customer Switching Laboratory in Denver, Colorado in 1976 where he worked on a variety of projects including pioneering work on direct T1 transmission interfaces and integration of data transmission devices and interfaces into customer switching systems. He provided systems engineering support on the engineering aspects and the introduction of electronic tandem networks. This work included considerable collaboration with account teams and early introduction customers.
He did exploratory development work on a data transmission infrastructure for customer switching systems. This work provided the underpinnings for product development work in which he also participated. He provided major inputs to the architecture team which defined the first all digital customer switching system, the System 85. He later provided architecture support on the migration to the distributed switching architecture which became the System 75 (later named the DEFINITY platform).
He was appointed a Distinguished Member of Technical Staff in 1983 and made major contributions to the bearer and signaling architectures fundamental to the integration and implementation of ISDN concepts. He fathered the concept of Frame Relay for user information transport through a digital network and became involved in ISDN standardization in both ANSI and CCITT (later ITU) as well as ECMA standards bodies. He chaired several standardization teams in both the US and Internationally. His contributions were fundamental to the definition of protocol and services including flow control and congestion management.
He was promoted into technical management in 1984 and led teams which developed complex signaling and bearer transport interfaces including T1/E1 interfaces (ISDN PRI) with integrated facility maintenance functions, X.25/X.31 and frame mode interfaces, ISDN Basic Rate Interfaces (BRI), performance and traffic monitoring and other service functions. He also had responsibility for FCC compliance testing.
In 1990 he led a team which pioneered a statistically multiplexed terrestrial infrastructure needed to support the CDMA wireless air interface. Pioneering concepts included synchronization and signaling mechanisms needed in support of the CDMA air interface including the support of simultaneous communications between a subscriber unit and multiple base stations. This pioneering work was fundamental to Lucent Technologies gaining a leading CDMA infrastructure market position. Concepts pioneered are reflected in present standards for CDMA based Second and Third Generation public wireless systems.
He has led teams in pioneering product evolutions while preserving customer investments in existing platforms. This work has included: migration to a TCP/IP based control architecture, migration to an X86 based controller architecture, applications co-residency capabilities, migration to converged backbone architectures which embrace ATM and/or IP, migration to distributed server architectures including high reliability and redundancy capabilities, hybrid networking migrations including both traditional and Voice Over IP capabilities, and migrations to enhanced voice processing and enhanced switch control paradigms. He also led efforts aimed at enhanced signaling architectures including Signaling System 7, IP networking security strategies, and other enhancements aimed at enhanced messaging and call center offers.
Mr. Spencer has originated many project proposals, dealing with both technical and business case aspects which have resulted in leading edge technical advances and market differentiating product offers. Examples include, for example, integrated facility management, ATM and IP convergence offers, and echo control strategies for converged networks. The fielding of these proposals has resulted in substantial revenues.
He has also collaborated extensively with account sales and services teams and strategic customers, both domestically and internationally, on platform technology and platform evolution issues. This collaboration has been instrumental to meeting customer expectations and needs in a timely and comprehensive manner. He has also collaborated extensively with market management and product development organizations developing public networking products including collaborations with strategic networking operators. Throughout his career, he has maintained an extensive network with knowledgeable personnel in the telecommunications world and has expended extensive efforts in maintaining currency in technology and networking offers.
Mr. Spencer has published including the Bell Labs Record and the Bell Labs Technical Journal and twice in conjunction with the International Telecommunications Union, World Telecommunications Forums in Geneva, where he presented papers on Frame Relay and CDMA/PCS Wireless Infrastructure at Telecom87 and Telecom95 respectively. Throughout his career, Mr. Spencer has pursued supplemental learning including pursuing a Mini-MBA from the Wharton School, Signaling System 7, Queuing Theory, Market Management for Technologists, Steven Covey Courses, RF system design, and many others in diverse management, business, and technical areas.
He was appointed a Bell Labs Fellow in 1999, being cited for: "Sustained contributions to global telecommunications in digital transmission, ISDN and Frame Relay standards, CDMA cellular telephony and PBX architectures."
Mr. Spencer has over 20 patents issued or pending in diverse areas such as CDMA terrestrial infrastructure, communications systems design, communications protocols including Frame Relay, networking convergence protocols and services, comprehensive echo control for hybrid networks, IP security, synchronization schema, and voice processing architectures.
Since forming Boulder Technology Labs, Mr. Spencer has consulted extensively in the area of telecommunications technology as applied to both public and private networks including next generation networking and wireless networking. He has consulted with legal firms and corporate clients in the area of intellectual property related to telecommunications art. Intellectual property consultation has included focus in the areas of researching and mapping given intellectual property to applications and realizations of given patented telecommunications art. He has effectively leveraged the breadth and depth of his knowledge of both technology and business aspects of telecommunications. Intellectual property consulting work has included involvement in many aspects of due dilligence, licensing, assertion, and litigation.
He is a member of Tau Beta Pi, Eta Kappa Nu and Phi Sigma Phi national honor societies and is a registered Professional Engineer in the State of Colorado. Mr. Spencer is a Senior Member of the IEEE. He lives with his family in Boulder. He founded Boulder Technology Labs, LLC in October, 2001 after his retirement from AVAYA Labs.
