MDS TransIt Series Overview

An MDS Transit system offers intelligent wireless networking products and network management software to support real time applications such as lottery terminals, ATM machines, POS terminals, water, gas and oil SCADA, etc. The Transit On-Line Transaction Processing (OLTP) system is a highly efficient wireless implementation that employs intelligent radios at each end of the wireless network. A Transit point-to-multipoint system is organized in cells. Each cell consists of one NM-200 master station and multiple NR-100 remote radios managed by Transit NMS (Network Management System) software. Multiple master stations are typically connected through a WAN to one or multiple processing centers.

Transit integrates into existing customer networks allowing the wireless network to seamlessly coexist with a wired network infrastructure. It provides intelligent network support for real time applications with a data transfer rate of up to 19.2 Kbps.

MDS TransIt NM-200 Product Overview

The TransIt NM-200 network master station utilizes DSP technology to offer a highly efficient network capability to support bursty data applications.

TransIt NM-200 supports multiple applications and network protocols. When the need for multiple applications arises, the NM-200 has five ports in support of five different network protocols. In addition, each NM-200 can manage up to 249 TransIt NR-100 remote radios. We designed the NM-200 to accept a full range of frequencies to complement TransIt NR-100’s capabilities, licensed radios (200 MHz to 960 MHz) and unlicensed spread spectrum radios (900 MHz). The TransIt NM-200 supports point-to-multipoint configurations and, when required, coverage can be extended with repeaters.

The TransIt NM-200 is a wireless master station that supports standard network protocols. It integrates into customer specific networks, allowing wireless data to seamlessly exist within the network infrastructure. When a transaction is received by the data port of the NR-100 remote transceiver, it is converted to an efficient radio protocol and only the data portion is transported over the wireless segment and into the master station.

The TransIt NM-200 master station delivers the transaction to the local data center host computer or alternately, sends the transaction across a wide area network (WAN) into a NM-200H host interface unit. The NM-200H converts the data back into the appropriate protocol and delivers it to the host computer.

The TransIt NM-200 series can be configured with its 5 data ports in support of multiple concurrent industry standard protocols (X.25, IP). It is a seamless solution that allows direct connectivity to a telco switch or cloud without the need for third party equipment. The TransIt NM-200 series improves access time by incorporating spoofing functionality to conserve bandwidth in polled systems and only using the channel when there is data to send.

Why Consider a MDS TransIt Solution?

Carrier-rated reliability that supports mission critical revenue producing applications. GE MDS is an ISO 9001 certified manufacturer of radio equipment.
Transit NM-200’s architecture offers a redundancy option at the master station for increased availability.
Transit NMS monitors every point on the network. With a Windows-based GUI it offers complete control and updated information to manage the network: alarms, statistics, diagnostic tools and remote control functionality.
Ease of integration – Transit is compatible with standard WAN transport protocols. Its multiprotocol capability encompasses the most comprehensive suite of protocols.
Efficiency – Transit operates on a single radio frequency allowing you to double the number of networks running on existing frequency pairs or to cut in half the expense to acquire new frequency pairs. Its multiprotocol capability reduces the need to support parallel networks for different services.
Rapid deployment – reduces time to revenue.
Flexibility to incorporate both licensed and license-free (spread spectrum) radios in the same system.
