Compatible Systems 1270i manual WAN Interface Configuration

Chapter 6 - Basic Configuration Guide 21

Suggested for IPX

You may want to set your own network numbers, rather than using the autoconfigured values. You may also want to turn off unused frame types.

CV: Use the IPX Routing: Ethernet 0 Dialog Box.

TB: Use configure and set keywords in the IPX Ethernet 0 (and/or Ethernet 1)section.

WAN Interface Configuration

In order to use a WAN interface, you may first need to set some phys- ical parameters and then set up the link and protocol parameters.

There are differences between the capabilities of the built-in T1 CSU/DSU WAN interface and the RS-232 WAN interface. The T1 interface can only be used with lines which run at fractional or full T1 rates. The RS-232 interface can be run synchronously or asynchro- nously, at rates up to 256Kbps (sync) or 230.4Kbps (async).

Internal T1 CSU/DSU (WAN 0) Physical Communications Settings

Required for Dedicated Line Operation

No changes from the default values are required for standard operation over a full T1. The default values are listed in Appendix A.

Suggested for Dedicated Line Operation

Changing to fractional T1, different coding or framing, etc., may be required for a particular installation.

CV: Use the Physical Configuration: WAN 0 Dialog Box.

TB: Use configure and the T1 Interface WAN 0 section.

RS-232 (WAN 1) Physical Communications Settings

You may need to set the baud rate, sync/async operation, and other physical communications parameters for the WAN interface. These parameters will depend on the line communications device you are using.

Note: Frame Relay is presently supported in the MicroRouter 1270i vonly via synchronous operation. An external clock signal is generated for Frame Relay.
