2 Hardware Installation
2.2 Connecting the Cable from the PC
Interface Card to the AVM ISDN-
Controller T1/T1-B
After you have installed the PC interface card, it must
be connected to the AVM ISDN-Controller
T1/T1-B.
To prevent interference in the high-frequency link, no
extensions should be added to the cable supplied.
1.
Connect the 15-pin sub-D connector of the cable
supplied to the upper socket on the back plate of
the PC interface card (see Fig. 1). Nothing needs
to be connected to the lower socket of the PC
interface card.
2.
Connect the 9-pin sub-D connector of the cable to
the 9-pin socket on the ISDN-Controller T1/T1-B
(see Fig. 3).
3.
Secure both connectors by tightening the finger
screws.
Now the AVM ISDN-Controller T1/T1-B must be
connected to the ISDN network terminator (NT).
2.3 Connecting the Cable from the ISDN-
Controller T1 to the NT
This section explains how to connect the cable from the
AVM ISDN-Controller T1/T1-B to the ISDN network
terminator (NT) installed by the ISDN provider.
The ISDN operator Deutsche Telekom AG uses various
types of NTs. For this reason, two different connection
procedures are described:
1. Connecting the ISDN-Controller T1 to the NTPM (NT
