Carrier Parameters 
Various settings are configurable for the RF Gateway 1 output carriers.  Some 
settings are configurable on an individual carrier basis, other settings are limited to a 
particular RF port (group of four carriers). 
To Configure Port Output Parameters 
1 Navigate to the QAMS page. 
2 Expand the tree menu and select desired RF Port.

Result: The RF Port Configuration window is displayed. 
 
3 In the Port Modulation field, select desired modulation (64 vs. 256 QAM). 
4 In the Port Output Level field, enter output level. 
5 In the Combined Channels field, select the number of active carriers per port (i.e., 
for four carriers per port, set Combined Channels to quad). 
6 In the Channel Number field, select channel frequencies. 
Note: Combined Channels are limited to be spaced contiguously (separated by 
the chosen channel spacing) from the frequency of the lowest carrier.  Therefore, 
only the frequency of the first carrier of a port may be configured.

Channel Application Mode 
The RF Gateway 1 operates in various network scenarios including table video, 
VOD, SDV, and data modes (pre-DOCSIS 3.0 wideband as well as full M-CMTS 
(DTI) scenarios).  These various scenarios are configurable on a per carrier basis, 
using the Channel Application Mode setting. 
To Configure Channel Application Mode 
1 Navigate to the Maps page. 
Result: The following window is displayed. 
 
2 Select desired Channel Application Mode. 
 Video 
 Data 
 SDV  
 NGOD 
 DEPI Learn 
 DEPI Remote 
3 Click Apply. 
4 Click Save.
