1.4.2.1 Users and lines
Telephony subscribers in internal areas can take part in voice
communications and, in the SwyxConnect VoIP environment, are
referred to as "users". The SwyxConnect differentiates between:
• ISDN users
A maximum of 40 terminal devices connected over the ISDN
network, including ISDN and analog devices connected to an
upstream ISDN PBX.
When connecting downstream PBXs to point-to-point lines, the
number of possible ISDN subscribers is determined by the
length of the extension number (DDI). In this case, all of the
telephones and terminal equipment connected to the PBX can be
mapped with a single ISDN user entry.
• Analog users
Two devices connected to the analog interfaces
• SIP users
A maximum of 32 SIP terminal devices connected over LAN,
WLAN and DMZ and analog devices connected with an ATA.
The external paths of communication available to the users are
known as "lines". The SwyxConnect differentiates between the
following lines:
