6 Controller C4 – 1 Introduction
1 Introduction
The AVM ISDN-Controller C4 is the ideal solution for all those
who need more than one ISDN BRI line. Equipped with a
high-performance CPU and on-board memory, the C4 can be
used for all kinds of communication tasks. All commonly
used digital communication protocols are provided. Analog
connections are also supported at up to 14.4 kbit/s. Incom-
ing or outgoing telefax connections can be processed over all
eight channels simultaneously.
Up to four active AVM ISDN-Controllers can be used in one
PC, so that you can meet your company’s growing communi-
cation needs by adding more ISDN-Controllers. This means
long-term security for your investments in ISDN hardware.
Mixed configurations with other active AVM ISDN-Controllers
for the PCI or ISA bus in the same computer are also suppor-
ted.
1.1 The AVM ISDN-Controller C4
The Controller C4 is an active ISDN-Controller with its own
high-performance CPU and on-board memory. The architec-
ture and technologies used are especially well suited to the
operating conditions found in server environments.
The driver software for the AVM ISDN-Controller C4 supports
all important communication protocols. Smooth communica-
tion is thus ensured with systems in ISDN, GSM cellular, ana-
log telephone networks and other digital networks.
The ISDN-Controller C4 allows you to connect a computer to
four basic-rate ISDN lines. You no longer need four bus slots
and four times the system resources to use eight ISDN B
channels. The ISDN-Controller C4 requires only one slot and
the system resources for one card.
Each of the S
