INTRODUCTION OF THE 3COM OFFICE CONNECT REMOTE 500 SERIES WIDE AREA NETWORK ROUTER

INFORMATION RELEASE

3COM OFFICECONNECT REMOTE 500 SERIES WIDE AREA NETWORK ROUTER

1. INTRODUCTION.

The 3Com OfficeConnect Remote 500 series router is suitable for extending a company's existing LAN a branch office and further.

Three models are currently available all with the same software capabilities and only differing in the number and type of WAN connections.

2. SPECIFICATIONS.

OfficeConnect Remote 511. This has only one ISDN port although both ISDN channels are accessible and can be bonded to create a single 128Kb connection.

OfficeConnect Remote 521. This model has the same features as the 511 with the addition of a voice port. This will allow a telephone handset to be attached to either end of the link and a single voice call made on an unused ISDN channel.

OfficeConnect Remote 531. This has the features included with the previous models plus a serial port (V.24, V.11 and V.35) which allows for direct connection to a leased line i.e. kilostream. This model can be configured to utilize the ISDN line if additional bandwidth is required or as a backup if the leased line connection fails.

OfficeConnect Remote features. All models have the following features.

Transparent bridging of all networked protocols.
IP and IPX routing capabilities.
NetWare protocol spoofing.
Data compression on all types of WAN link.
Supports Point to Point Protocol (PPP) allowing the router to be used for internet access via an ISP.
Can operate as a Domain Name Server (DNS) and supports Dynamic Host Configuration Protocol (DHCP).
Supports Network Address Translation (NAT).
Has built in firewall software for increased security.
Can be managed via a serial terminal or PC with emulation software, telnet session or SNMP management software.
Can be stacked and integrated with other 3Com products and managed by 3Com Transcend software.

The rear panel has the following connection present as described below.

Power should be supplied be the external transformer supplied with the unit.

RESET For use by 3Com Technical Support only.

SERIAL Attach the serial management terminal to this port. The terminal should be configured at 9600 baud, 8 data bits and no parity. It should use a VT100 emulation mode.

COAX Use this port to attach to a 10Base-2 Ethernet LAN segment. If this is required, make sure nothing is attached to the 10Base-T LAN port.

MDI/MDIX This switch determines the type of connection that the 10Base-T LAN port provides. If the unit is connected to a hub then the switch should be set to the IN position. If the device is attached directly to a PC network adapter then the switch should be set to the OUT position to enable the crossover.

WAN (531 only) This is a 25 way D-type female connector used to attach the unit directly to a leased line. The port supports X.21/V.11, V.24/V.28 and V.35/V.36 standards up to 2Mb.

10BASE-T Use this port to attach to an 10Base-T network via an RJ45 connection. Make sure nothing is attached to the COAX port if this connection type is required.

ISDN Using an RJ45 connection attach the ISDN line to this port.

VOICE (521 and 531 only) Using an RJ11 connection an standard PSTN telephone handset can be connected to this port. A BT to RJ11 converter is supplied with these models.

Resetting to Default Values.

Before configuring the device, it is recommended that it is reset back to factory defaults. This should be done as follows.

The following message will be displayed.

This will ERASE all configurations. ERASE (Y/N) ?

Type Y and press Enter.

The unit will now reboot, this may take a few minutes.

Once rebooted, press Enter when prompted and log in as normal.

Type SAVE and press Enter to store the changed settings.

Type QUIT and press Enter to log out.

Remove the power connector from the rear of the unit and then refit the lead to reboot with the cleared configuration.

This will ensure that all configuration information has been cleared.

5.1. BRIDGE OPERATION.

The bridge configuration is slightly simpler to implement than that of a router but will allow all protocols to be transferred across the link. This can lead to excessive amounts of data being transferred and cause the link to slow. This type of configuration is suited to small single site networks or leased line connections.

IP Addressing in Bridge Mode.

To minimize the amount of unnecessary network traffic sent across an ISDN link and therefore the cost of its usage, some thought should be given to the allocation of IP addresses.

On a bridged network all IP addresses must be within the same IP network. For example, if the host server is configured with an address of 129.1.1.1 and a netmask of 255.255.0.0 (standard for a class B address), all devices must be configured within the 129.1 network. If the ISDN autocall numbers are configured in this fashion too much data is likely to be unnecessarily transmitted across the link. By using a netmask this can be substantially reduced.

By using the next octet it is possible to subnet the remote sites. For example, if a remote site’s IP addresses are grouped as 129.1.10.xxx and a netmask of 255.255.255.0 is used then only data relevant to the 129.1.10 network would be sent across the ISDN link. Other sites can then be configured by selecting other values for the third octet i.e. 129.1.20, 129.1.30 etc.

This netmask would only be used in the configuration of the local bridge, the remote bridge should still maintain the 255.255.0.0 netmask to allow it access to all other devices within the same network.

The IP address and netmask would only be required when configuring the autocall numbers, not the port address. See details later on.

Bridge Setup.

Reset the unit to its default value as described previously.

Type CO and press Enter to select the Configuration menu.

Type SY and press Enter to select the System Parameters screen.

Most of these parameters should be left at their default values as above. Make sure that the Network Type is set to Europe, including UK (ETSI).

The option Maximum Call Duration can be changed to prevent unwanted long calls being made if a problem occurs. This will cause the bridge to force a disconnection of the line even if data is being transferred. The call will be automatically re-established if a valid data connection is required.

It is possible for two bridges to share the same ISDN-2 line and these can be configured to only use one particular ISDN channel. This is achieved by changing the Aux Working (UK Only) option from Disabled to either B1 Only or B2 Only. This will force the bridge into using only the channel specified.

This should now be repeated for all bridges being configured.

Testing the Connection.

A simple ping test can be done to prove that the configured link works.

From the local server, ping the local bridge to make sure that the local network can see the device.

Ping the IP address of the remote bridge to open the ISDN link and prove the WAN connection. The ISDN light on the front of the unit should light and briefly some of the ISDN utilization lights should show.

Finally ping a device at the remote site to prove an end to end connection.

These tests can also be performed in the reverse direction to confirm a bi-directional operation.

5.2. ROUTER OPERATION.

The router mode of operation requires more knowledge about the network and type of protocols being used to allow it to be configured correctly. A router will only allow certain protocol types to be transferred across the link, this does allow for more control on the type and amount of data being sent. This type of configuration is more suited to larger network installations across all forms of WAN connection.

IP Addressing in Router Mode.

On a routed network each site must be on a different IP network address. For example, if the host server is configured with an address of 129.1.1.1, then since this is a class B address the remote sites would need to have different network numbers i.e. 129.2, 131.10 etc.

Default and static routes would also need to be added to the configuration of each network device to allow them to find the remote network devices. Alternatively a routing protocol such as RIP would need to be enabled on each server to provide similar information to the rest of the network. This type of configuration is highly dependant on the operating systems involved and will not be covered in this document.

Router Setup.

Reset the unit to its default value as described previously.

Type CO and press Enter to select the Configuration menu.

Type SY and press Enter to select the System Parameters screen.

Enter the IP Address of the network being connected to i.e. 129.10.0.0 for a unit at the local end of a link and 129.1.0.0 for the remote unit.

Enter the appropriate IP Mask for the device being configured i.e. 255.255.0.0 for a class B address.

Enter the Remote Unit name as specified previously when adding the ISDN number of the remote unit (see the previous step).

Set the Idle (secs) timeout to a suitable value. Too short and the router will be constantly dialing and dropping connections. Too long and call charges may become excessive. This timeout value is the length of time that the connection will remain up without any data being transferred. A value of between 15 and 60 seconds should be workable.

Press Control-E to submit the changes.

The IP Autocall Address screen will be redisplayed with the new entry now listed.

Testing the Connection.

A simple ping test can be done to prove that the configured link works.

From the local server, ping the local router to make sure that the local network can see the device.

Ping the IP address of the remote router to open the ISDN link and prove the WAN connection. The ISDN light on the front of the unit should light and briefly some of the ISDN utilization lights should show.

Finally ping a device at the remote site to prove an end to end connection.

These tests can also be performed in the reverse direction to confirm a bi-directional operation.
