Installing The Module

2-7

You also need a proprietary communications software package such as 

Windows ‘Terminal’ to communicate with the module’s management 

system. See the

 AccessBuilder ISDN Access Router Software Reference

 for 

more information about managing the module.

WAN Ports 

(8 & 9)

These ports are used to provide connection to a WAN over a private 

leased line. The port terminates with a SCSI connector. This port 

supports any of the CCITT data transmission standards; X.21/V.11 

V.24/V.28 (RS232), and V.35/V.36 at data transfer rates up to 2 Mbps. 

Provided that connection cables that follow these standards are used, 

the unit automatically detects the type of interface that the port is 

required to support, and configures it accordingly. 

Refer to 

Appendix A

 for information about the WAN interface cables 

required. Suitable cables are available from your 3Com reseller as spare 

parts, refer to 

Appendix A

 for the required item part number.

The PRI Bridge/Router Module supports up to eight ISDN channels. 

However, if you use a WAN port, one less ISDN channel can be supported. 

If both WAN ports are used, a maximum of six ISDN channels can be 

supported by the module.
