R2 Card Specifications
Administration of R2 Card Software
The IMAT (ISDN Maintenance and Administration Tool) application is used to perform operation
and maintenance functions on the R2 card. You can use IMAT to download R2 card software
for backup and upgrade purposes and to install or restore the database.
IMAT runs on an independent computer with a Windows 95, 98, or 2000 Professional operating
system and is connected to the R2 card through a serial link. The IMAT computer accesses
the R2 card either through a direct connection on-site or remotely through a modem.
To install the IMAT application, see the README.TXT file on the R2 card software CD-ROM.
For more information on IMAT, refer to Using the ISDN Maintenance and Administration Tool
(IMAT).
Software Upgrades
Use IMAT to upgrade the R2 card software and to install or restore the database. For more
information on upgrading R2 card software, refer to the IMAT online Help.
Details of how to perform software upgrades are given in Upgrading or Re-installing R2
