6000SERIES INTELLIGENT NETWORtí PROCESSORS The Codex 6000 Series Intelligent Network Processors (INP's) present the most advanced means of managing your data communications network. Based on an ad­vanced multi-microprocessor architecture, the 6000 Series provides economy, distinctive performance characteristics, and advanced degrees of flexibility to solve your most demanding data communications problems. More intelligent than a multiplexer, and more economical and efficient than a concentrator, the 6000 INP offers unique data handling functions at the nodes of your net­work. By distributing intelligence through the network, and by performing tasks that cannot be accomplished by tra­ditional devices, the 6000 INP provides centralized net­work control and monitoring for ali nodes, including the gathering of statistical measurements of network perfor­mance, and the detection and reporting of abnormal conditions when preset thresholds are exceeded. The 6000 INP statistically combines information from a large number of terminais as traffic is offered. Dynamic bandwidth allocation allows the 6000 INPto handle more terminais than a traditional time division multiplexer for a given trunk speed. A data compression feature which substitutes short codewords for frequently used charac­ters further increases throughput. This combination of statistical multiplexing and data compression provides overall savings by decreasing modem and line costs. The 6000 INP is operationally transparent, and NO spe­cial equipment or software engineering is required for in­tegration into y.our planned or existing system. Its modular design provides for growth in both size and functionality, trom line concentration up to distributed network monitor­ing and control. In addition, the Codex 6000 Series INP implements a full-duplex GO-BACK-N ARa (automatic repeat request) internodal protocol, assuring error-free communications.

THE 6000 SERIES INTELLIGENT NETWORK PROCESSORS FEATURE: • Error-Free Transmission • Operational Transparency • Network Management and Performance Monitoring • High Throughput Efficiency • Modular Expandability • Data Compression • Network Configuration Control • Multinode Capability • Intermixed Data Rates and Protocols • Autospeed • System Diagnostics • Capacity for up to 248 Terminais • Multiplexed Network Interface to Codex 6500 Series

Communications Front-End Processors

EXTENSIVE NETWORK CAPAlILITIES

LOWCOST REMOTE DATA CONCENTRATION The Codex 6000 Series INP's provide efficient concentra­tion and data compression, allowing you to transmit data streams from up to 24810w to medium speed terminais over one high speed line. With its error-free data trans­mission and high throughput, the 6000 INP reduces line requirements to substantially decrease your communica­tions costs.

REPLACEMENT OF CONVENTIONAL TDlts On high spe.ed traffic links, the Codex 6000 Series INP's require a narrower digital bandwidth than a TDM, due to the INP's concentration and data compression features. The resulting transmission cost savings alone can justify the replacement of a TDM. The benefits of error control, enhanced network control and diagnostics are an added bonus.

ORAMATIC RESULTS IN BISYNCHRONOUS ENVlRONMENTS The 6000 INP can dramatically increase the efficiency of bandwidth utilization in BSC environments. The band­width in terrestrial or satellite links, which ordinarily goes unused due to the half-duplex nature of BSC protocol, can be re-allocated by the 6000 INP to additional syn­chronous or asynchronous devices. This means that more terminais can communicate without additional costly communications links.

NETWORK liROWTH THROUliH MODULAR EXPANSION The Codex 6000 INP offers a variety of feat~res and hardware and software options lhat allow you to expand its capabilities as your data communications needs grow. To increase capacity, you can increm~ntally add terminal ports, throughput capability or memory storage by simply inserting additional plug-in modules. Features such as autospeed and custom data compression can also be easily incorporated at any time. And, as your system grows, the Codex 6000 Series INP's will keep pace with your requirements for sophisticated network monitoring and control.

NETWORK INTEGRATION The Codex 6000 Series Intelligent Network Processors permit the integration of multiple applications-oriented networks under one transparent data transport system, despite an extensive mix of terminal types and host CPU's.

TURNKEY COMMUNICATIONS NETWORK FACILITY The combination of the powerful network processing capabilities of 6000 INP's with the advanced communica­tions features of the Codex 6500 Series Communications Front-End Processors (FEP's), presents a turnkey com­munications network facility that can be tailored to meet your specific applications. It allows Vou to upgrade your network, instead of your mainframe. The Multiplexed Network Interface Capability of the 6500 Series FEP's permits you to extend your network capa­bilities to remote locations over a single physical connec­tion to remote 6000 INP's. And, the multiplexing capa­bilities of the 6000 INP's allow multiple data terminais to communicate with your host computer. This interfacing scheme lets you achieve more efficient utilization of your processing resources, while increasing throughput and functionality.

ADVANCED FEATURES

ERROR-FREE TRAN5MI5510N Using a highly efficient full-duplex ARO scheme for node­to-node communication, the Codex 6000 Series INP's assure you of error-free transmission in the network. In addition, optional features are available to automatically monitor the quality of the communications links.

CENTRALlZED NETWORK CONTROL Vou can achieve centralized network control with the Codex 6000 INP by either of two options.

An Operator Console can be used to select , examine and modify a variety of system configuration, status and per­formance data anywhere in the network. 11 also serves as a hardware diagnostic/ test panel during installalion and maintenance. The other system control device is a Con­trol Terminal Porl which allows local or remote monitoring, interrogation and reconfiguration. This port may be inter­faced to most asynchronous terminais or directly to your Codex 6500 FEP or host computer.

NETWORK MANAGEMENT The 6000 INP's Network Management feature provides full capabi lity for the collection, computation , and cen­tralized reporting of statistical measures of system per­formance. Vital advance information of potential bollle­necks or inefficient resource ulilization is therefore at your fingertips. Typical information includes: character error rates of terminais, processo r loading, memory utilizalion , data compression efficieney, line utilization, and traffie density. In add ition, the Monitoring Option supplies re­ports whenever abnormal conditions oeeur, or user preset threshold leveis are exeeeded, while the Statistics Option produces longer term performance data in response to operator interrogation.

MULTlNODE CONFIGURATlON5 The Codex 6000 INP is designed to support the intercon­neetion of two or more nodes in a network. A variety of mullinode distributed eonfigurations, where eaeh node may be eonneeted to one or more neighboring nodes, ean be structured, permitting you to alie r the interconneetions of source/destination pairs.

INTERMIX OF TERMINAL5 Eaeh terminal porl module is capable of supporting asyn­chronous or BSC synehronous terminais , with other paekages available on special request. Configuration changes to port type and characteristics can be handled direetly from the Operator Console or the Control Termi­nal Porl. No hardware strapping or board replacement is necessary.

• Synchronous speeds (internai clock): 1200,2400, 3600, 4800, and 7200 bps

• Any externai clock speed up to 7200 bps • Asynchronous speeds:

75, 110,134.5,150, 300,600, and 1200 bps Additional speeds are available on special order.

OPTlON5 AUT05PEED The Codex 6000 INP Autospeed Option provides auto­matic configuration of a terminal pari to match the bit rate and charaeter format of data from an asynchronous ter­minal. This feature allows a single terminal porl to supporl a variety of asynchronous terminal speeds, without any operator intervention.

5UPERVI50RYCOMMUNICATlON55UPPORT The Supervisory Communications Supporl (SCS) Option gives you an "Engineering Order Wire" type of faeility on 6030/ 6040 INP systems. 11 provides automatie message routing between network control personnel at ali or at seleeted nodes of your network. Flow and error-control capabilities implemented by SCS route supervisory communications around link failures.

REPORT LOGCiINCi The Report Logging/Control Terminal Porl (RUCTP) Option automatically presents and logs system reports at user-selectable intervals. Ali reporls include time stamp data, and may be output as they oecur, or may be queued and output at preset intervals. The RUCTP is applicable with any asynchronous ASCII terminal equipment. 11 provides standard control terminal functions in addition to reporl logging.
