Soneplex Broadband and Soneplex Loop Extender Systems Alarm/Performance Remote Retrieval Options
This application note provides detailed alternatives for transporting the Soneplex Broadband and Soneplex Loop Extender alarm and performance information from a remote location back to the central/hubbing location. The Soneplex Broadband System is used as an intelligent network hub for DS1 hicap distribution in the local loop. The network interface is one standard electrical DS3 signal. This DS3 signal is demultiplexed into twenty-eight DS1 circuits, which can then be delivered to up to twenty-eight remote locations utilizing either fiber or copper facilities....

DSX-3 75 ohm Circuit Termination
DS3 Network Elements (NE) such as fiber optic terminals (FOT) or M13 multiplexers (M13) that are cabled to the DSX-3 require a 75 ohm load to stabilize the output signal. This 75 ohm load or 75 ohm termination prevents the output from oscillating and affecting adjacent channels. When a NE is cross-connected to another NE, the output of each NE is terminated by the input of the other NE. When multiple NEs are installed, many are often unassigned for a period of time until working service is required. Although unassigned, the NEs are powered up Hot in a standby mode, waiting to be turned up live as...

DS3 FLC Distance Learning
Several schools utilize distance learning to meet demands for greater variety in their curriculum. Distance learning entails transmitting a presentation or lecture from one location to several remote locations for students to observe. Distance learning offers several benefits to the traditional classroom setting. It provides for a more effective use of an educator’s time, and allows a specialist's expertise to be spread across a wider audience. In addition, distance learning permits the sharing of resources between institutions and increases the availability of a broader curriculum to the student body. In short, distance learning solves educators’ problem of providing more variety with fewer resources....

UNBUNDLED COPPER DELIVERY SOLUTIONS
It's an exciting time to be a competitive local exchange carrier (CLEC). With more carriers entering the market, customers know they have many options for service. In fact, shopping around for the most economical and best quality solution is becoming almost as basic for businesses as casual Fridays. For new competitors, the key to getting customers' attention is finding a cost-effective way to deliver and differentiate their services. The opportunity is clear when CLECs take a look at the exploding T1 service delivery market. T1 services are growing at 30 to 40 percent annually to meet the demand for hicap voice, ISDN-PRI, Frame Relay, Internet access,...

HDSL2 : INTEROPERBILITY AND BEYOND
In order to function, services transported over traditional HDSL require transceivers at both ends — central office and customer premises — provided by a single vendor. Standards currently being considered for its replacement, HDSL2, would allow transceivers from different vendors to interoperate. The obvious benefit for purchasers of such devices is the freedom to “mix and match” components from different manufacturers, increasing competition and ultimately reducing costs. But the real, long-term benefits of interoperability are less apparent and far more important....

Soneplex® PCS System Collocated in the BTS
The Personal Communication Services (PCS) network is a digital network that has the same basic components and standards as cellular networks. A PCS network consists of a mobile switching center, base station transceivers or cell sites, and base station controllers connected to a network service provider. The mobile switching center typically handles 100,000 subscribers. It connects the radio network to the service provider’s telephone network. The base station controller handles link handoffs, acts as an administrator for the location register and concentrates and routes the traffic from several cell sites to the mobile switching center....

DSX-3 Cable and Cross-Connect Limits
The DSX-3 is a common point in central offices or network nodes that provides the following functions: • Termination of a variety of equipment referred to as network elements (NE). The NE are permanently cabled to this common point during the initial installation and remain terminated at the DSX-3 for the life of the equipment. • Cross-connection of two NE together to configure a circuit. The cross-connect jumper is a semi-permanent connection that may be changed as the telephone network evolves and circuits are re-configured to meet service demands. As new equipment is introduced into the network, this replaceable jumper facilitates a means to re-connect equipment together throughout the...

RF Signal Management Traditional Splitter/Combiner Installation and Cable Management
Successful signal management in headends of the future will be determined in large part by one issue: the ability to manage the dynamic environment of the return path. New services such as the addition of multiple channel lineups or narrowcast insertion of telephony, PCS, network management or data services, demand two-way signaling and the development of a robust reverse path. At the same time, providing excellent customer service requires a high level of network reliability, often achieved through headend redundancy....

Soneplex® Loopback
There are several ways which loopbacks can be placed in and on Soneplex units for extended testing of circuits. Listed are several ways of providing these loopbacks: 1. At the HLXR location, provide a physical cord loop from the Network “IN” to the “OUT” jacks on the face of the unit. This provides a hard loop to run any stress test the customer requires. Once testing is completed, this cord loop will have to be removed. 2. If a repair person is at the customer location, they can access the HLXR unit and from the Main Menu, go to the HLX Configuration screen and change the Loopback...
