Optimum ADSL Utilization
9 NT/MPRI – 1 Introduction
ler C4 is supported at the basis rate interface (BRI), the BRI version of
the NT/MPRI can be expanded to up to eight channels. In the version
for the primary rate interface (PRI) up to 120 B channels can be used.
The driver software for the AVM ISDN-Controller in Windows XP/Win-
dows 2000/NT computers is included in the NT/MPRI package. It is lo-
cated on a separate CD entitled “Server Edition”. The driver software
supports the DSS1 (Euro ISDN) D-channel protocol as well as the com-
mon national protocols.
The NT/MPRI uses and controls the ISDN connection through AVM
ISDN-Controllers, over which it can be operated either directly on the
public ISDN network (point-to-multipoint or point-to-point access) or at
a Private Branch Exchange (PBX).
The following types of leased lines are also supported (designations of
the Deutsche Telekom AG):
l Digital 64S (B channel 1x64 Kbit/s)
l Digital 64S
2
(B channel 2x64Kbit/s)
l Double-switching Digital 64S (B channel 2x64Kbit/s, split be-
tween two users with 1x64Kbit/s each)
l Digital S
0
/TS
02
(B channel 2x64 Kbit/s + D channel 1x16 Kbit/s)
The AVM ISDN-Controllers B1, C4 and T1-B offer support for GSM in ac-
cordance with the Mobile ISDN standard (GSM 07.08), enabling reliable
and seamless network connections over ISDN even via GSM and
HSDCSD (High-Speed Circuit-Switched Data).
Optimum ADSL Utilization
ADSL (Asymmetric Digital Subscriber Line) is a technology which
makes Internet access at a high bandwidth possible using normal tele-
phone lines. ISDN and ADSL use different frequency ranges, enabling
parallel operation free of interference.
