period, you should navigate to Site Configuration | Ethernet and then click the Disable

Setting the Maximum Information Rate (MIR)
What is the MIR
The maximum Ethernet throughput of the link (MIR) can be limited. The default setting is
Best Effort
(see Figure 8-15 above), where the highest information rate available for the link
conditions and settings is used.
What is it for
The MIR setting limits the throughput for Ethernet service. It does not affect the capacity of
TDM services.
If the Link Budget Calculator or air conditions limit the capacity to X Mbps, and suppose that
you use Y (< X) Mbps for TDM services, then you are left with X - Y=Z Mbps for Ethernet.
Suppose for example, that Z = 20 Mbps.
As a Service Provider, you can decide to sell a package based on 10Mbps and charge $P1 for
it, or 15 Mbps for $P2 > $P1.
The MIR setting allows you do this.
The default value is “best effort” (shown as “Unlimited”) which will give Z above.
To limit the Ethernet information rate:
1. From the Configuration menu, choose the site to reconfigure.
2. Click Advanced | Ethernet
The Configuration dialog box opens.
Note
The minimum value is 256 Mbps.
The maximum value will be the minimum between Z above and -
• 50 Mbps for RADWIN 2000 B
• 10 Mbps for RADWIN 2000 PDH
• 50 Mbps for RADWIN 2000 L
• 20 Mbps for RADWIN 2000 X
• 200 Mbps for RADWIN 2000 C
The MIR setting is independent per direction.
