In the Management Tree, right-click an MMU2 H.
Point to Configure and click Configure Radio Link to open the MMU2 H Configuration page.

145. Terminal ID — The name or id number of the Radio Terminal
Terminal Parameters
Terminal ID — The name or id number of the Radio Terminal
Far End ID — Specifies the expected identity of the Radio Terminal on the other end of the radio link. If Radio ID Check is enabled, this identity must match the identity of the far-end terminal.
Radio ID Check — Controls that the received traffic originates from the correct far-end Radio Terminal; if not, an alarm is generated.
Mode — Specifies the protection mode of the Radio Terminal. Note:   Protection modes other than 1+0 require a license.
Not Defined — Indicates a mismatch in a protected Radio Terminal. For example, it has been configured as 1+1 Hot and then one MMU2 H is removed.
1+0 — Specifies an unprotected Radio Terminal.
1+1 Hot — Specifies a protected Radio Terminal in hot standby mode. Only available if there are two units in the correct positions.
1+1 Work — Specifies a protected Radio Terminal in working standby mode. Only available if there are two units in the correct positions.

146. Capacity
Enable XPIC — Selecting the check box enables XPIC while clearing the check box disables XPIC. If an error causes XPIC to disconnect, the button Restore XPIC after Fault appears. The error cause must be corrected before the button is clicked. Note:   XPIC requires license for PDH modems, for example, MMU2 H.
Adaptive Modulation — Enable or disable Adaptive Modulation.
Channel Spacing (MHz) — Specifies the selected channel spacing. Only supported channel spacings are available for selection.
Reference Spectrum Efficiency Class — Specifies the static value for Reference Spectrum Efficiency Class when Adaptive Modulation is selected. Only visible when Adaptive Modulation is enabled.

147. Fading Rates — There are two possible values:
50 dB/s High Throughput
100 dB/s High Fading Resistance
Fading Rates is only shown when Adaptive Modulation is selected and Max Capacity – Modulation and Min Capacity – Modulation do not have same values.
Capacity – Modulation — Specifies the traffic capacity and modulation of the Radio Terminal. Only supported combinations of capacity and modulation for the selected channel spacing are available. After the capacity value, the frame format version is stated within parenthesis. Unknown indicates that an invalid combination of settings is selected. Only available when Adaptive Modulation is disabled.
Packet Link Capacity — Displays the Packet Link Capacity in Mbit/s for the selected Channel Spacing and Capacity — Modulation. Only available when Adaptive Modulation is disabled.

148. Tx Freq. (MHz) — Transmitting frequency. RF
Tx Freq. (MHz) — Transmitting frequency.
Rx Freq. (MHz) — Receiving frequency
Output Power Mode — Specifies how the output power is controlled.
Fixed (RTPC) — The output power is set from a management application.
ATPC — The output power is set automatically depending on the received input power in the far-end RAU.
Output Power (dBm) — Specifies the output power in dBm.
Transmitter On — Selecting the check box turns the transmitter on.
XPIC
Companion Pos — Position of pair connected MMU2 H/F in an XPIC configuration.

149. Configuring Switching with MMU2 H
In the Management Tree, right-click one of the MMU2 H.
Point to Configure and click General.
