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 
 
 
 for information about the WAN interface cables 
 
required. Suitable cables are available from your 3Com reseller as spare 
 
parts, refer to 
 
 
 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.
