3. Right-click on the HOST Site Number (see
Figure 4-6
). The Site Number pop-up screen
will open. Enter any number between 1 and 24 and then click on OK to close the screen

4. Check the REMOTE Site Number field (see
Figure 4-6
). The REMOTE Site Number
does not have to be entered. When the HOST Site Number is entered, the system will
automatically enter the same number for the REMOTE Site Number.
automatically enter the same number for the REMOTE Site Number.
5. Right-click on the REMOTE Site Name field (see
Figure 4-6
). The Site Name pop-up
screen will open. Enter a unique name for the REMOTE. The name may be up to 32
characters long and must not contain any spaces. The name may include numbers,
punctuation, and upper or lower case letters and must always begin with a letter. Click on
OK to close the screen and make the changes take effect.

6. Open the Tools menu at the top of the main window and then select Refresh Catalog to
make the new Host and Remote site names appear in the View menu.
2.5
Enter Host Forward Attenuation
The HU internal forward path attenuator setting determines the maximum composite output
signal level at the STM antenna port. The appropriate attenuation value for any particular
system is based on the number of channels the system is transporting and the level of the
composite forward path signal input at the HU’s FORWARD RF IN port. The maximum output
power that can be provided by the system is 40.5 dBm (11 Watts). The total forward path gain
that is provided by the system (with host and remote forward attenuators set to 0 dB) is 80.5
dBm. Use the following procedure to set the forward path attenuation to provide the maximum
composite output signal level:

composite output signal level:
1. Click on the HOST RF tab. The HOST RF display will open within the EMS main
window as shown in
Figure 4-8
.
2. Right-click on the Host Fwd Att section of the display (see Figure 4-8). The Host Fwd
Att pop-up screen will open as shown in
Figure 4-9
.
3. Obtain the value of the total composite input signal level as determined in step 10 of
Section 2.3
.
4. Determine the appropriate value to enter for the Host forward path attenuator by
subtracting the required system output level (per system design plan) from 80.5 (the total
system gain) and then adding the composite input signal level. The result (see sample
calculation) is the amount of attenuation required.

calculation) is the amount of attenuation required.
Atten Required = 80.5 – (Required System Output Power) + (Composite Input Power)
5. Enter the attenuation value and click OK to close the pop-up screen and to make the
changes take effect.
