Scalable multiservice switch

HIGH-CAPACITY ATM SWITCHING PLATFORM is engineered specifically for use within the service-provider network. Designed to meet NEBS requirements, with DC power and carrier-oriented timing and synchronization options, General DataComm's APEX-NPX is one of the leading platforms for delivering ATM services in demanding public networks. GDC APEX-NPX offers multiservice provisioning of voice, video, and data, while benefits of its deployment include lower trunking costs of national and international voice networks. Advantages of APEX-NPX include smooth migration from legacy and frame to ATM-based solutions and a fully standards-based approach conforming to ITU, ATM, and Frame Relay Forum recommendations.

To enhance port density in its Voice-over-ATM platform, General DataComm has introduced 8 kbps CS-ACELP compression (ITU-T G.729A) as an upgrade to its APEX Voice Service Module (VSM). Together with existing silence suppression algorithms and standards-based AAL2 variable-bit rate (VBR) Voice, VSM users can now enjoy bandwidth savings of up to 8:1 with as many as 120 voice channels per VSM. The addition of the 8 kbps CS-ACELP algorithm provides the high port density 8 kbps VBR Voiceover-ATM product, with each GDC APEX system capable of supporting up to 1,800 compressed voice channels. This density and the inherent modularity of the GDC APEX design ensures the product is ideal for both customers who require low numbers of channels for private networking between digital PBXs and those who require higher densities for applications such as the backboning of public voice services. The GDC APEX VSM Voice-over-ATM solution offers over twice as many voice channels per system compared to competing products.--General DataComm, Inc.

Electronic signature pad

NEED A SIMPLE WAY TO SIGN electronic documents? Recognizing the trend toward the paperless office, Interlink has developed ePad, an innovative pen input device to sign and store documents electronically. Capturing handwritten signatures for PC applications is useful in authorization of e-commerce, e-mail messages, and on-line banking transactions. Interlink's ePad allows access to signature-based electronic security systems. It uses a pressure-sensitive input pad, Interlink's VersaPad. When used with its pen-input software, ePad captures signatures and inserts them into Microsoft Word documents. Interlink's software permits "signature binding" (affixing and time-stamping of an electronic signature to a document), is compatible with other signature binding software packages, and supports biometric signature verification.--Interlink Electronics

Wireless LAN at 5 GHz

DELIVER 24-MBPS DATA RATES over your wireless LAN network. Proxim is developing a high-speed product line based on the HIPERLAN Type 1 wireless LAN standard. Projected to be available in early 2000, RangeLAN5 products will support real-time multimedia applications, video distribution, and voice communications. HIPERLAN-based products operate in the 5-GHz band and deliver 24 Mbps data rates, more than twice that of 11 Mbps wireless LAN products. The HIPERLAN wireless LAN standard specifies support for isochronous services. Because they are operative at 5 GHz, HIPERLAN systems do not interfere with installed 2.4-GHz wireless LANs, decreasing the possibility of downtime or reduced throughput of existing systems. --Proxim, Inc.

Mobility server

LUCENT TECHNOLOGIES has produced a server that enables wireless capability for most PBX or Centrex systems. In a move that broadens Lucent's multivendor approach for business systems, the Lucent Mobility Server now integrates the DEFINITY wireless business system with switches from companies such as Ericsson, Nortet Networks, Hitachi, Siemens, Rolm, and Panasonic. The server also can create a unified network of switches from multiple vendors that share the same phone features and dialing plan. This support of a multivendor approach to wireless systems allows businesses to build off their embedded networks and to get the immediate benefit of in-building wireless services.

The DEFINITY Wireless Business System offers mid- and large-size businesses the flexibility and convenience of wireless communications with the same features and functions of desktop telephone sets. The system's pocket phones can handle three phone lines and make it easy for users to screen, forward, transfer, and hold calls. The phones have conference call capabilities and can access and forward voice mail, picking up virtually all of the features of a deskset.

The system has a transmission range of 2.4 million square feet and can support 1,500 pocket phones. DEFINITY allows for 12 simultaneous calls per fixed base station, 96 calls per zone, and 260 simultaneous calls per network--the highest density in the industry. The system operates at a low power level in the 1.9 Ghz frequency range so it does not interfere with sensitive equipment.

The Lucent Mobility Server is available in a stackable, single-carrier unit, or for larger enterprises, a multicarrier unit. Depending on customers' requirements, the mobility server interfaces with a PBX or Centrex in one of two ways. With the station-side interface, the PBX supplies a bridged analog connection to the Mobility Server. With the trunk-side interface, the PBX supplies tie trunks, such as through an ISDN PRI interface, to the Mobility Server.--Lucent Technologies

AcceSS7 applications

ENABLE TELECOM NETWORK OPERATORS to implement some of the provisions of recent FCC rulings on intercarrier compensation for ISP-bound traffic. Hewlett-Packard has developed two HP acceSS7 business-intelligence applications to help identify and measure Internet traffic. The HP acceSS7 ISP finder application identifies and tracks Internet service providers by comparing calling patterns against a typical ISP calling pattern. HP's acceSS7 interconnect ISP-analysis application allows operators to measure the volume of ISP-bound traffic as a percentage of the total traffic they send to or receive from specific interconnecting operators. Network operators can use this data to apply the correct rating factors when calculating payments under interconnect agreements. Hewlett-Packard
