Trunk Groups Of Network Interfaces - ASCOM Ascotel 2025 System Manual

4.1.1

Trunk Groups of Network Interfaces

General Rules and Settings
A network interface can only be assigned to a single trunk group.
A trunk group contains either analogue or digital network interfaces (the network
interface entered first is decisive).
The digital network interfaces of a trunk group lead either
• to the permanently networked PISN if "network type = private" is set,
• to the public network if "network type = public" is set.
The following rules apply to the setting of the transmission protocol ("Protocol")
for the network interfaces of a trunk group:
• Trunk groups with "type of network = private" are usually set to the QSIG pro-
tocol.
PSSI (QSIG) set.
• Trunk groups with "Network type = public" are set to protocol DSS1.
Tip:
It is advisable to enter network interfaces that have the same destination
in the same trunk group, for example to set up one trunk group for the
public network, one trunk group for PINX 1 and one trunk group for
PINX 2, etc. (see also planning suggestions in Part 3).
Initialization Settings
Newly set up digital network interfaces are automatically entered in trunk
group 1.
Trunk group 1 is set to "Network type = public" and "Protocol = DSS1".
Newly set up analogue network interfaces are automatically entered in trunk
group 2.
Trunk group 2 is set to "Network type = public".
