For more specific configuration information, please refer to your User Guide and you may also find information within other documents in the Perle Knowledgebase.

Solution:

A1.	Does the JetStream8500 have all the functionality of the older JetStream6000 and MTS? Yes. The 8500 can do everything the JetStream6000 does - with superior performance, ease of management and network access functionality built in.
A2.	Can I get a port on one JetStream to talk to a port on another JetStream, in effect creating a serial data pipe across the network? Yes. The ports are configured using TCP socket numbers to link a port on one JetStream to a port on another JetStream, allowing data to flow in both directions. This is useful for connecting serial based, remote machinery or monitoring equipment back to a central system using the existing network infrastructure.
A3.	The JetStream8500 offers SNMP support. What is this and how can it help me? Simple Network Management Protocol (SNMP) is a network management protocol widely used in TCP/IP networks. SNMP communicates between a management program run by an administrator (HP OpenView) and the network management agent (JetStream8500). SNMP is being used more and more these days to aid in the management of networks. Using this protocol, it is possible to query the status of various network components, (i.e. routers, managed hubs, servers, etc), and in some cases to configure the units. With the JetStream8500 and SNMP you can achieve the following : View product configuration and versions Obtain statistics on IP usage Configure the unit Receive notification of problems.
A4.	I want to connect branch offices to the head office system. How can Perle help? One of the best ways to connect your serial equipment in the branch office to the head office is to use a JETSTREAM8500 and a couple of routers (such as P-Series) over a kilostream or ISDN line. Just connect a Router to the head office network and to the ISDN. At the other end of the ISDN, connect the other Router for the branch office network. A JETSTREAM8500 is then linked to the network to provide the necessary serial ports for terminals, printers etc.
A5.	I want to connect branch office printers and terminals to the head office system. One of the best ways to connect your serial equipment in the branch office to head office systems is to use a JETSTREAM8500, JETSTREAM4000 or LANSTREAM2000. The 2 sites can be linked using a router/access server combination giving TCP/IP access from one network to the other. Terminals and printers can then be connected using Telnet, Rlogin, RCP & LPD or using Perle software such as TruePort.
A6.	We are a network management company with a requirement to access serial management ports on a variety of equipment (e.g. routers, workstations, PBX, etc). We need to be able to access these across a TCP/IP network. The JETSTREAM4000, JETSTREAM85000 and LANSTREAM2000 can be used to give access to serial port from the network. The JETSTREAM ports are configured for reverse telnet and each one given a unique TCP socket number, e.g. 2000. From a PC (or server), with network access, you can then telnet to the individual ports by using the following syntax "telnet ipaddress 2000". This will give direct access to the port. To protect against unauthorised access, connections can be restricted to systems listed in the JETSTREAM host table.
A7.	How many user accounts can be configured on a Jetstream? All Jetstreams have an internal user database which can hold 32 individual user accounts. If more accounts are needed then an external Radius server will need to be used.
A8.	Can a port be locked to a particular user? Yes. In the port settings for each port there is a user field. If a valid username is entered into the field then only that user will be able to access the port.
A9.	Why would I need Trueport software? If using the Jetstream as a terminal server then normally the ports are setup to Telnet to particular Unix servers. However some applications, such as accounting, need to now what terminal performed what transaction. To achieve this the application often needs to use fixed port addresses. By loading Perle's trueport onto the server it can be configured to create the fixed ports permanently linking to the desired terminal. There are also appications that need to attach to dumb devices such as barcode scanners which cannot make a connection and so the server must initiate the connection. Again this is done by loading Trueport and then the devices can be accessed through fixed TTY or Fixed COM ports.
