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.
