CHASE IOLAN

Chase IOLAN Terminal Server
Technical Data Page

IOLAN is a feature rich Ethernet TCP/IP terminal server which enables serial devices to be connected directly to LANs. The serial devices can be terminals, printers, modems, bar code readers or any other RS232 device. With a simple to use menu-driven interface, installation can be achieved in minutes.



ARCHITECTURE

IOLAN is used wherever serial devices need to be connected to LANs. IOLAN uses a standard physical ethernet connection and TCP/IP for the software connection. IOLAN conforms to the most commonly used standards ond offers a flexible metod for serial connection.

Serial connections using RS232 ecable IOLAN to connect to a wide range of devices. IOLAN implements the full nine pin connection on both the DB25 and RJ45 connectors, which many other vendors ignore. This allows even the most complex asynchronous devices such as high speed modems to be connected directly to the IOLAN and fully controlled without loss of data or performance.

IOLAN is available in a variety of different packaging styles including rack-mount and stand-alone.

APPLICATIONS

With IOLAN's flexibility it can be used in a large number of applications, from workgroup computing to modem pooling. IOLAN is used extensively for multi-user computer peripheral sharing.

Typical devices that are connected include:

PERFORMANCE

IOLAN has the performance you need to handle a diverse range of high speed devices in complex applications envirenments. IOLAN can transmit data at speeds up to 115.2Kbps. This allows high performance devices to function at very high speeds.

To achieve this high speed and to maintain a high throughput, IOLAN utilizes the performance of RISC based CD180 OCTARTs in combination with highly tuned firmware.

EASY INSTALLATION

IOLAN setup can be performed in a matter of minutes using our unique menuing system. A minimum configuration requires only the IP address to be set. for installtion requiring further setup, the IOLAN will assist you in stepping through the additional configuration options including port speeds, flow control, security and PPP/SLIP connections.

RELIABILITY

Reliability is the single most important aspect of any network device. IOLAN comes with a lifetime warranty (as does every Chase product). This is a practical demonstration of faith in both the build quality and design of the product.

FLEXIBILITY

IOLAN can be configured as either a dedicated virtual connection or the menuing system can be used to give multiple host access. With a dedicated connection, the network is transparent to the userand access is provided to a single pre-selected host. In the menuing mode, the user can hot-key between fou simultaneous sessions per port. IOLAN can handle all ports running 4 sessions simultaneously up to the maximum of 64 separate connections.

MANAGEMENT

Administrators have access to any IOLAN on the network using remote access (via telnet). This facility allows remote configuration and diagnostics. IOLAN also supports the SNMP (Simple Network Management Protocol) at MIB-I, MIB-II and Chase specific enterprise variables. Using SNMP, the network or system administrator can be advised about various conditions that appear on the network, often anticipating problems and correcting them before the users have noticed.

PRINTING & MODEM SUPPORT

IOLAN is a versatile printer and modem server. Printing devices can be configured as local printers on a UNIX host using the Chase supplied daemon software. Alternatively, the RCP or LPD protocols can be used on a port enabling IOLAN to act as a remote print queue. This allows any system on the network to interface printouts on one print queue or access a hunt group. Te high bandwidth provided by IOLAN makes it the right choice for all types of printer connections.

Modems and other bi-directional devices can be configured as local TTY ports under UNIX and appear as COM ports under DOS/Windows, using a combination of IOLAN features and reverse telnet software. This allows programs such as CU, UUCP, KERMIT and many other communications packages to use IOLAN ports without modification. IOLAN is a perfect platform for modem pooling, not only because of its high speed but also the enhanced security. Individual ports can have multi-level password protection. Security can also be enhanced by using a dedicated connection to a predetermined host. Access to the administrator's menu is also password protected and can be enabled/disabled on a per-port basis.

COMMUNICATIONS

IOLAN can be used in applications beyond those normally associated with terminal servers; with it wealth of software features IOLAN can be catagorized as a communications server. An IOLAN configured for PPP/SLIP connections will allow remote network connections over serial lines. Remote users will appear directly connected to the LAN. The IOLAN acts as a router by forwarding IP traffic between the LAN and PPP/SLIP connections.

One of IOLAN's strongest features is Reverse Telnet which is configurable on a per port basis and can be used to allow systems that do not support ethernet or TCP/IP to be networked. The reverse telnet feature also used by the Chase supplied host software to create seamless serial port connections for modems and printers. These connections appear as local UNIX ports and can be used with most any application or system administration tool. Reverse telnet can also be used to make IOLAN a front end TCP/IP processor allowing non-networked systems access to the LAN.
