Signaling Message Monitoring
Configures the logging PC address pool. In the signaling application you select the pool
entry to be used, so different signaling applications can use different logging PCs.
The logging PCs are connected to the internal subnet of the instrument. Thus the first
two address segments are determined by the subnet configuration. The other parts sup-
port only a limited range. Assign compatible addresses to the logging PCs.

4.4.9 IP Subnet Configuration
This section configures the internal IPv4 subnet of the instrument. This is only relevant
for instruments equipped with an "Ethernet Switch H661A" (option R&S CMW-B661A).
The option includes two LAN SWITCH connectors at the rear panel, providing access to
the internal subnet. This is for example required for signaling message monitoring via an
external PC. The external PC is connected via the LAN SWITCH to the internal subnet
and thus to the signaling units.
The R&S CMW500 subnet uses the subnet mask 255.255.0.0. IP addresses belonging
to the subnet are structured as follows.
IPv4 address = w.x.y.z:
●
w.x:
Network ID, identifying the network segment used by the subnet. The network ID is
identical for all IP addresses belonging to the subnet. Example: 172.22.y.z.
●
y:
Node ID, identifying a network node within the subnet (subnet node). You must con-
figure a different node ID for each instrument and PC belonging to the subnet.
●
z:
Adapter ID, identifying a network adapter within a subnet node.
Some applications provided by the R&S CMW500 require that you establish a direct
connection between the LAN REMOTE connector and the LAN SWITCH and assign a
specific IP address to the "Lan Remote" network adapter. To do so, plug the patch cable
delivered with option R&S CMW-B661 into the LAN REMOTE connector and connector
1 of the LAN SWITCH. Assign the subnet conform IP address w.x.y.3 to the "Lan
Remote" network adapter via the configuration dialog, see "Network Adapter"
on page 103.
The patch cable and the subnet conform "Lan Remote" IP address are required by the
following applications:
●
Selftest "Unit Test > IP Access Test External"
(requires "User (Extended)" mode, see "External Tests" on page 94)
●
Protocol testing (requires option R&S CMW-KP080) without using a Data Application
Unit (R&S CMW-B450A)
●
Monitoring of signaling messages via an external PC without using a Data Application
Unit.
