Data solutions for Frame Relay and X.25 networks

RAD’s packet switching family includes packet assemblers/

disassemblers (PADs) and multiprotocol packet switches.

All are designed to the latest ITU specifications and ANSI

recommendations. They support various protocols,

including HDLC, async, SLIP, PPP, IP, and ISDN. The

products can be used to transport Frame Relay and X.25

over IP or to construct high performance, private X.25/

Frame Relay networks or efficient extensions of public

X.25/Frame Relay networks. In addition, RAD offers a wide

range of interchangeable interfaces, such as built-in CSU/

DSUs and ISDN BRI terminal adapters.

GPRS connectivity

For backup and special access purposes, the async

channel can connect to a GPRS modem to transmit data

where wire lines are not available, or for backup purposes.

Remote Ethernet connectivity

RAD’s remote connectivity solutions offer a range of

products that provide users with the desired transparent

connectivity and their corporate network managers with

the flexibility to choose the WAN services, port quantities

and security features that best suit their applications.

Management over extended Ethernet and IP

networks

Management of networking devices over increasingly

complex, heterogeneous environments has created

challenges for carriers and corporate network managers,

as well as for vendors of communications equipment.

RAD’s unique combination of routing technology and

modem and E1/T1 technologies provides comprehensive

support of Ethernet and IP to answer customers’ remote

management needs. Plugging devices such as the

TinyBridge into the Ethernet management port of any

network device, for example, allows immediate remote

management access over any available WAN service. This

enables transparent management of the remote

networking device, as if it were connected to the local

network.

Rate and interface converters

RAD’s wide range of converters provides conversion

between different interfaces. Depending on the

application, the conversion may involve one or more of

the following:

• Electrical: converting the signal levels

• Physical: providing a different connector type

• Functional: converting the functional operation of

the signals

• Speed: converting from one data rate to another

Fiber optic distance and bandwidth

Distance and bandwidth are determined by fiber type and

light source.

Fiber type – There are two types of fiber optic strands:

multimode and single mode. Multimode fiber allows

propagation of light along various paths, resulting in high

attenuation, while single mode fiber allows a single

transmission path, which results in lower attenuation and

higher speeds.

Light source – Signal attenuation in fiber optics also

depends on wavelength. Low attenuation occurs at three

different wavelengths: 850 nm, 1310 nm and 1550 nm.

RAD's fiber converters support connectivity over these

different fiber types and light sources.

Converters and Connectivity

Many IT users still work in an environment using legacy equipment typically

characterized by lower speed data rates and specialized data communications

protocols. RAD is one of the few vendors in the market today offering connectivity

products for these devices.
