You can attach the included handles to the Gateway and mount it onto a 19-inch rack.


The Digital Gateway requires EIA/TIA 568-A Category 5 cabling for trunks and Category 3 (or higher) cabling for 10BaseT connections. Both cables require standard RJ-45 connectors. Cables and connectors are not supplied.

Installing the Digital Gateway's Software

Installing the software for DT-24/DE-30 involves copying necessary files from the CallManager and transferring them to the DT-24/DE-30.

To install the DT-24/DE-30 software:

Step 1   On a PC running DOS 6.22, Windows 95, or Windows 98, create a bootable floppy. For example, insert a floppy and type format /s a: at the command prompt.

Step 2   Perform one of the following procedures:

Step 3   On the PC you used in Step 1, copy the file "" to the floppy. Do this only after you have completed Step 2.

Step 4   On the floppy disk, edit the autoexec.bat file using Figure 1 as an example. First, edit the subnet mask. Then, edit the IP addresses for the DT-24/DE-30, the subnet's default gateway, and the DNS server. Use if an address is not used.

Step 5  

On the floppy disk, edit the TFTP server's IP address in the file dacfg.ini using Figure 2 as an example.

Step 6   Insert the disk into the floppy drive of the DT-24/DE-30 and power on the gateway. The gateway's hard drive is reformatted. This can take up to 5 minutes. A long beep signals when the process is complete. Do not continue until disk activity is complete.

Step 7   Remove the floppy and reboot the DT-24/DE-30.


This device cannot be connected to the public switched telephone network (PSTN) in countries outside of North America.
