Platform Introduction Today, network planners face a dilemma. Since the future of standards and services remains unclear, there is a healthy concern about investing in what may become “deadend” technol- ogy. Still, networks must grow and change, both to provide current revenue and to accom- modate emerging services and markets, while competition and deregulation add to the sense of urgency. The penalty for delay is stagnation. On the other hand, choosing the wrong path wastes current resources and blocks future growth. The Soneplex ® Intelligent DS1 Service Delivery Platform lets you build today, while preserving future options. The Soneplex platform offers a modular architecture which supports copper and fiber optic transport facilities in point-to-point and point-to-multipoint topologies. By integrating network interface, access, and management functions, the Soneplex platform substantially reduces your required inventory. The Soneplex platform lets you install the facilities which will earn you revenue today, and add new ones as demand – and revenue potential – grows. The modular design makes change, such as upgrade from asynchronous to synchronous interface, easy, often simply a matter of swapping cards. The Soneplex system also improves your return on costly, skilled human resources. Preprovisioning is easy and cost effective, so turnup of services can be handled quickly, inexpensively, and often remotely. The same is true of system administration and mainte- nance. This, coupled with sophisticated self-test and notification capabilities, gives you a critical edge as networks grow larger and more densely packed. Most important, the Soneplex system keeps your options open. You can continue to use existing infrastructure while you plan your future. Today’s HDSL or DS1 modules, interfacing to copper, can operate side-by-side with optical DS2 modules interfacing with fiber. As your needs change, the Soneplex platform will evolve with you. Growth and change become part of your strategic plan. As networks are required to do more, cost less to operate, and perform more reliably, the Soneplex system lets you build with confidence. The system accommodates a range of asynchronous and SONET interfaces, DS3 and STS-1. Upgrade from copper to fiber can be as simple as a change of modules. Two basic Soneplex systems are designed to meet all of your loop access and transport needs, from the central office to network hubs to large customer sites. The Soneplex Loop Extender System distributes services from DS1 feeds. The Soneplex Broadband System lets you distribute services from DS3 or STS-1 high bit-rate interfaces. The intelligence built into the Soneplex system lets it take an active part in network manage- ment. The system provides simple, flexible access to the network for remote testing, and monitors many aspects of the network measuring user-defined parameters and sending alarms, or even rerouting traffic when error-rate thresholds are exceeded. These capabilities can substantially reduce, or even eliminate, many of today’s costs of service initiation or system maintenance. The Soneplex DS3 Remote Control System allows central office control of a remotely located Soneplex Broadband System by transporting individual circuit information via an embedded DS3 communications channel without using valuable bandwidth. Introduction Financially Sound Soneplex System Makes Sophistication Simple 4 3/97 481 3/17/97 11:00 am The Soneplex system’s high-density, multifunction design combines the functions of a variety of network elements: multiplexers, DSX bays, office repeaters, fiber optic extension shelves and monitoring devices. It simplifies installation, saves valuable space and eliminates multivendor products. Each chassis is made up of three primary sections: one for network interface, another for service distribution, and a third for network management and maintenance. The high-speed network interface section of the Soneplex Broadband System accepts DS3 inputs and eliminates the need for external M13 multiplexers. It also supports STS-1 synchro- nous electrical input – an inexpensive form of connection to collocated equipment – performs VT mapping, and has time-slot assignment capability. The service distribution section of the system supports up to 28 modules for delivery of DS1 hicap service over conditioned or unconditioned copper or fiber facilities. High bit-rate digital subscriber line (HDSL) modules perform 2B1Q conversions for transport of hicaps over non repeater-equipped copper. Optical DS2 modules convert electrical signals to optical, trans- porting 4 DS1 signals over a DS2 fiber link. The management and maintenance section consists of a main processor unit (MPU) and an alarm processor unit (APU). The system supports TBOS and TL1 interfaces for remote connection to an operations support system (OSS). It also supports an easy-to-use, menu- driven craft interface, and X.25 and alarm contact closure interfaces. HDSL signal transport allows local exchange carriers to continue to earn revenue from existing copper infrastructure. Each HDSL module allows one DS1 signal to be transported up to 12,000 feet over copper without the use of line repeaters, bridge taps, or cable pair separation. The addition of an HDSL repeater doubles the effective delivery distance to 24,000 feet. HDSL compensates for gauge changes, and tolerates the presence of near-end crosstalk. RLX modules in the chassis will extend DS1s, and power up to 10 span repeaters on a single unconditioned copper circuit. Each 19" shelf supports 20 modules. The standard Soneplex shelf supports up to 28 modules serving as many as 28 customer sites. For fiber transport, optical DS2 modules can operate side-by-side with HDSL cards. Up to seven customer sites can be supported by each Soneplex chassis. One optical module per site provides unprotected 6.3 Mbps service (4 DS1s). Two modules per site provide 1+1 protection. The combination of HDSL and optical DS2 modules provide: T1 hicaps, T1 transport of digital loop carrier, T1 video using the latest compression techniques, fractional T1, and cell-site connection for cellular telephony transmission. The system’s remote OSS interface and onboard management capabilities make it ideal for unstaffed sites or operations with limited staffing capabilities. Remote provisioning and monitoring simplify setup and routing maintenance demands. Realtime and historical performance monitoring, and remote loopback and bit-error testing greatly reduce the demands on technical support personnel. System Design and Capabilities II.

Implement what your customers are willing to pay for, and build new infrastructure as revenues allow. Instead of placing new burdens on personnel, the Soneplex platform lets them offload time consuming chores to the system itself. Technicians acclimate quickly, using familiar existing support systems, and can access large areas of the network remotely. As technology and the network grow and change, the Soneplex platform adapts quickly and easily. Today’s rebuild becomes tomorrow’s card swap. Migration to fiber, SONET, and new support systems becomes easy and economical. The Soneplex platform solves the network planning dilemma. Soneplex Platform: Focus on Function Soneplex Platform in Summary 6 3/97 481 3/17/97 11:00 am III. System Introduction The Soneplex Broadband system is a flexible, cost-effective platform which provides DS1 services in point-to-point or point-to-multipoint applications while providing a DS3 or STS-1 network interface. To meet the short turn-up intervals that exist in today’s competitive market, different modules can be mixed within the chassis to match the transport facilities already in place. These modules include the Optical DS2 (ODS2), the High bit-rate Digital Subscriber Line Module (HLX), the Repeater Loop Extender Module (RLX), and the DS1 Loop Extender (DLX). The Soneplex Broadband system accepts a standard electrical DS3 or SONET STS-1 signal on the network side and can be used with any multiplexer, DCS or network element that gener- ates standard DS3 or SONET STS-1 signals. The Soneplex Broadband system consists of a rack mount chassis, electrical carrier - 1 (EC1M) and virtual tributary mapper module (VTMM) for STS-1 interface, a DS3 mux module for DS3 interface, and up to 28 low speed modules which extend up to 28 DS1 circuits over either copper or fiber. A main processor unit (MPU) provides the interface from the transmission modules to the operation support system (OSS). An alarm processor unit (APU) provides a critical/major/minor contact closure appearance to the telemetry alarm system (TAS), as well as housekeeping alarm inputs. DS1 transport schemes employed by the Soneplex Broadband system include: • High bit-rate digital subscriber line (HDSL): The HLX modules perform a DS1/HDSL 2B1Q signal conversion to transport hicaps over repeaterless copper twisted pairs. An inline HDSL repeater may be used to double the transmission distance to 24 kft. • Repeatered DS1s: The RLX modules transport repeatered DS1 signals over copper facilities. • Optical DS2: The ODS2 modules perform electrical/optical conversions, allowing up to four DS1 circuits per module to be transmitted over a 1:1 protected or unprotected fiber optic link. This module is housed in the Soneplex Broadband chassis and interfaces with a QLX module located at the remote location. • Quad Loop Extender: The QLX modules perform electrical/optical conversions, allowing up to four DS1 circuits per module to be transmitted over either a 1+1 protected or unprotected fiber optic link. This module is located at the remote and interfaces with the ODS2 modules located at the central location. • DS1 Loop Extender: The DLX extends one DS1 up to 655' to a DSX-1. Introduction Description 7 3/97 481 317/97 11:00 am III. System Introduction The Soneplex Broadband system provides a variety of interfaces for interconnection into office alarm systems and operations centers. At the heart of this operations feature set is the direct TL1 connection to the X.25 network. This connection is accomplished via a synchronous output from an EIA-232 port controlled by the MPU. This port eliminates the need for an intermediate Packet Assembler/Disassembler (PAD). Operations The rear of the Soneplex Broadband chassis has three serial interface ports. Port 1 supports an EIA-422 telemetry byte oriented serial (TBOS) protocol interface. Port 2 is a serial EIA-232 25- pin D subminiature connector that supports either craft interface or TL1 commands. Port 3 is also a serial EIA-232 25-pin D subminiature connector that can support three logical connec- tions over one X.25 connection. These logical connections can be in the form of either permanent virtual circuits (PVCs) or switched virtual circuits (SVCs). The virtual circuits can be configured for craft interface or TL1 commands. The Soneplex Broadband system stores all revision level information to allow local or remote inventory via the craft interface terminal or remotely through dial-up access or X.25. Future software upgrades to the Soneplex Broadband system are performed through a download procedure, which may be accomplished locally through the craft interface or remotely through dial-up access. For external back-up protection of system parameters, the system can upload and download from the MPU its specific configuration database. This operation is effected from a personal computer using a standard file transfer program with the configuration stored in a disk file. The download procedure of the database will be similar to the MPU software download. MPU-specific administrative and provisioning information is retained on the HLXC, VTMM or DS3 MUX Plus modules for database and restoral purposes. Therefore, if MPU replacement is necessary, no external data transfer or back-up protection is required.

System Introduction Modern maintenance philosophies center around the premise of being alerted to potential service outages before the problem manifests itself. Through full-time DS1 performance monitoring, the Soneplex Broadband system provides unparalleled insight into the actual service level delivered to the customer. Extensive maintenance features are provided by the Soneplex common equipment and the service modules themselves. Trouble isolation and sectionalization is accomplished through loop backs. Front panel indications, along with visual and audible alarms, provide local notification of critical, major and minor alarms as well as other maintenance conditions. User access is provided through VT100 emulation, using any personal computer or laptop computer terminal. This capability is available remotely through dial-up access. Protection switching architecture is employed on any service-affecting interface carrying multiple DS1s. The high speed interfaces are all protected 1:1. The optical low speed interfaces are protected 1+1. The Test Access Unit (TAU) is an optional maintenance device that provides monitor and intrusive test access to the DS1 channels in the chassis between the VTMM/DS3 MUX and the low speed distribution modules (DLX, HLXC, ODS2, and RLX). Access is provided through Bantam jacks on the TAU front panel and is controlled through the Craft Interface. The TAU requires the B1 DS3 MUX and MPU Version 4.2 or later. The DS3 Soneplex Remote Control System provides an embedded DS3 communications channel between a DS3 mux installed in a remote Soneplex Broadband and a DS3 path terminating device located at the central office. The embedded channel provides remote alarm hauling, performance monitoring and provisioning capabilities of the Soneplex Broad- band shelf from the central office. Critical circuit information utilizing craft interface or TL1 can be collected from seven remote locations from a single point, eliminating the need for a costly overlay network to transport data. All provisioning is performed locally or remotely through the craft interface. Depending on the service delivered, a minimum number of options must be set to enable the circuit. Provisioning information is stored in non-volatile memory, and is maintained in the MPU even during power down conditions. Each module also retains its own provisioning informa- tion in case the MPU itself needs to be removed and replaced. The new MPU is then updated automatically by each module in the Soneplex chassis. A standard TL1 message set is supported through logical channels in the X.25 link. Customer circuits may be enabled, disabled, reprovisioned, looped for trouble isolation or interrogated for performance information via this link.
