Frame relay connectivity

CONVERGE SNA, LEGACY AND IP APPLICATIONS across frame relay with one device. The 4300 FrameNode from Sync is a frame relay router optimized for high fan-out branch networks. It features a variety of connection options, including a FT1/T1 DSU/CSU for connecting to the frame relay network, BRI ISDN terminal adapter, token ring or Ethernet LAN interface, up to six serial data ports for SNA or legacy applications and an RS-232 local network management port for on-site management of the box. The 4300 runs FrameNode software to deliver SNA session rerouting, automatic dial backup, frame relay bandwidth allocation and burst managment, IP branch routing, and circuit management. The automatic dial backup feature can use either a v.90 analog modem or an ISDN connection to maintain the WAN connection in emergency conditions. A built-in service modem allows for out-of-band network management of the device. The unit is 1.71 "x 7.32"x 1.313" and weighs 8 lbs.-Sync Circle 313 for more information

Fiber repeater

EXTEND FIBER-BASED NETWORKS up to hundreds of kilometers with a protocol-independent, hot-swappable module for IMC Networks' iMcV Chassis Series. The iMcVFiberWay is a new line of fiber extender/repeater modules designed for network installers connecting remote offices and other applications that require medium- to long-fiber runs. Upon receiving data through the cable, iMcV-FiberWay retimes the signal, removing jitter and amplifying the data, then retransmits the signal. Long data hops are possible, reducing the cost of additional switches in long-distance WAN installations. IMC Networks' fault isolation circuitry helps cable installers rapidly identify the location of a broken fiber cable should one occur. In addition to helping overcome distance, the iMcVFiberWay can provide a single conversion between 1300 nm multimode, 1300 nm single-mode and 1550 nm single-mode fiber. The modules support transmission speeds of OC1, Fast Ethernet, OC3, OC12, Fibre Channel and Gigabit Ethernet. The iMcV Chassis Series can also host an SNMP-compatible systems management module to monitor and manage all conversion modules and power supplies within the chassis.-IMC Networks Circle 317 for more information

WAN router with twinax

IMPLEMENT E-BUSINESS ACCESS SOLUTIONS without abandoning SNA applications and hardware with a high-performance router that includes integrated twinax terminal server support. The new Perle SmartServer 400e high-performance router provides a complete solution for mixing Ethernet LAN connections, dialup PCs, locally attached serial devices and voice connection over a wide area network (WAN). The SmartServer 400e can connect over one or two high-speed digital leased lines, with analog or ISDN connections available for primary and backup WAN connections. It is also voice over IP ready to deliver voice and fax traffic over a single network for reduced inter-office communication costs. The unit maximizes bandwidth to increase WAN performance by taking advantage of high-speed, leased-line digital services and data compression, as well as ISDN bandwidth-on-demand. It has a modular and scalable design for growing user populations and can handle all types of data interfaces, including synchronous, asynchronous, Twinax and LAN protocols. Integrated network security ensures secure access. Comprehensive network management and diagnostics simplify ongoing operation to maximize uptime.-Perle Circle 316 for more information
