4.3 Configuring Service Parameters
The user defines the type of service required, Ethernet Only or Ethernet with
TDM. The bandwidth remaining available for Ethernet if TDM services are required
is shown in the dialog box.
Airmux-200-L versions are Ethernet Only.
In the Service Parameters dialog box select if Airmux-200 is to provide E1/T1,
(x1 or x2 for IDU, or x4 for IDU-E). Define the required transmission rate, and the
distance between the sites.
 To configure E1/T1 and Ethernet services:
1. In the Service dialog box, select one of the following:
 Ethernet plus a number of E1/T1 channels (see
Figure 4-6 ).
 Ethernet data only.
2. Select the transmission rate required.
 Adaptive
 12 Mbps
 18 Mps
 24 Mbps
The default rate is Adaptive. Airmux-200-L versions only operate in adaptive
mode.
Adaptive Modulation - The system changes modulation automatically
depending on channel characteristics in order to guarantee continuation of
service. The adaptive modulation enables the user to maximize Ethernet
throughput without degradation of the TDM service quality. When Ethernet
only service is used, the adaptive modulation enables improving the Ethernet
performance in case of air performance degradation (periodical interference
or RSS changes).
In event of interference at one site, there is no need to use a lower
modulation at the other site (as in previous versions). In such a case the
actual rate changes automatically only at the problematic site, while the
second side of the link maintains the highest rate possible (Asymmetric).
Adaptive modulation can be changed in both Installation and Configuration
wizards.
3. Type in the distance between the sites.
If TDM services are selected, then the Evaluate icon shows on the screen
whilst the maximum rate is evaluated.
When evaluation is complete the icon changes and the following message
is shown:
Service has been evaluated, click Next to continue.
4. Click Next.
