1 Introduction to the AVM ISDN-Controller T1/T1-B
protocols V.110, V.120 and ISO 3309 are also sup-
ported. The ISO 3309 protocol is used primarily in the
field of GSM cellular communications, as with Mobile
ISDN.
The AVM ISDN-Controller T1/T1-B conforms to the
ITU-T I.431 recommendation and supports all 30 B
channels and the D channel of the S
2M
interface at
64 Kbit/s. On the ISDN D channel, the T1-B supports
both the European DSS1 protocol and the national
protocol 1TR6. The controller has international approv-
als for use throughout Europe.
The driver software is available for the operating
platforms Novell NetWare, Windows NT and MS-DOS.
Several AVM ISDN-Controllers can be easily combined
in one PC. Up to four active AVM ISDN-Controllers can
be operated simultaneously.
Installation of the ISDN-Controller hardware and soft-
ware completely connects the PC to ISDN.
