First you have to determine the transmission mode. Via
keypad you select between G.711 (3.1 kHz, telephone), G.722
(7kHz, H.221/SRT), Layer 2 and Layer 3.

The input menu asks for the ISDN number to be entered
using the numeric keypad as usual. Dialing is initiated by
pressing the ‘Enter’ key.

The connection parameters are determined as follows:
When entering only one ISDN number: 64 kbps, 48 kHz,
mono, user data 1200 baud.
When entering two ISDN numbers: 128 kbps, 48 kHz, Joint
Stereo, user data 1200 baud.
The audio input is taken from the ‘Accept Configuration’.
The used ISDN Sync is always ‘AUTO’. You can select
between AUTO, H.221 and SRT for the G.722 mode.

You can easily monitor your audio transmission. After a
connection has been established and the audio parame-
ters have been exchanged, the online transmission menu
is displayed.

It informs you of the send and receive levels, connection
time as well as the set headroom. In addition to the trans-
mit (Tx) and receive (Rx) configurations, the IP address or
ISDN number of your connection partner is displayed.

Once an ISDN connection has been established, not only
the connect time but also the $ icon for connection charges
is displayed. The actual connection charges can only be
displayed on an ISDN line of the German Telecom after
being respectively activated.
