The following table describes the labels in this screen.
Table 25:
The Basic: MoCA Screen
Bridge Name
Use this field to modify the name of the CGNM/ CGNM-
3552 on the network. This allows you to identify the
specific device by the room in which it is installed when
you assign a unique Bridge Name to each device on the
MoCA network.
Select the room type from the drop-down list.
Figure 32:
Bridge Name Options
Channel Plan
The MoCA specification defines several channel plans
for communication on the cable network (see
The
Multimedia over Coax Alliance
on page
8
). This field
allows you to select the channel plan that you want the
CGNM/ CGNM-3552 to use.
Select the channel plan that you wish to use from the
dropdown list.

Channel
Use this field to define the channel on which you want
the CGNM/ CGNM-3552 to communicate on the cable
network, dependent on the
Channel Plan
that you
selected.
Select the channel plan that you wish to use from the
dropdown list. If you select SCAN, ensure that you also
configure the
Scan Range (Start)
and
Scan Range
(End)
fields.
Figure 34:
Channel
Scan Range (Start)
If you selected
SCAN
in the
Channel
field, use this field
to select a channel at which the CGNM/ CGNM-3552
should start scanning for a connection on the cable
network.
Scan Range (End)
If you selected
SCAN
in the
Channel
field, use this field
to select a channel at which the CGNM/ CGNM-3552
should stop scanning for a connection on the cable
network.
TxPower
Use this field to set the power at which the CGNM/
CGNM-3552 transmits (TX) over the cable network,
from
0
to
10
.

BeaconPwLevel
Use this field to set the CGNM/ CGNM-3552’s beacon
power on the cable network, from
0
to
10
. The MoCA
beacon allows other devices on the cable network to
detect the CGNM/ CGNM-3552.
NC Type
Each MoCA network has a Network Coordinator (NC)
which acts as a manager for all the other devices on the
cable network.
By default, the NC is chosen from the pool of MoCA
devices based on its suitability (signal strength, etc.)
To base NC status on merit, or if you have specified
another device as “preferred” and do not want the
CGNM/ CGNM-3552 to compete with it, select
Auto-
negotiated
.
When one device is set to be the “preferred” NC, it will
be the NC whenever it is available on the network (if
multiple devices are “preferred”, the most suitable one
will be chosen). Select
Preferred
to add the CGNM/
CGNM-3552 to the preferred group.

Wireless Overview
This section describes some of the concepts related to the
Wireless
screens.
5.1.1
Wireless Networking Basics
Your CGNM/ CGNM-3552’s wireless network is part of the Local Area Network
(LAN), known as the Wireless LAN (WLAN). The WLAN is a network of radio links
between the CGNM/ CGNM-3552 and the other computers and devices that connect
to it.
5.1.2
Architecture
The wireless network consists of two types of device: access points (APs) and
clients.
The access point controls the network, providing a wireless connection to each
client.

Hitron CGNM/ CGNM-3552 User’s Guide
The wireless clients connect to the access point in order to receive a wireless
connection to the WAN and the wired LAN.
The CGNM/ CGNM-3552 is the access point, and the computers you connect to the
CGNM/ CGNM-3552 are the wireless clients.
5.1.3
Wireless Standards
The way in which wireless devices communicate with one another is standardized by
the Institute of Electrical and Electronics Engineers (IEEE). The IEEE standards
pertaining to wireless LANs are identified by their 802.11 designation. There are a
variety of WLAN standards, but the CGNM/ CGNM-3552 supports the following (in
order of adoption - old to new - and data transfer speeds - low to high):
IEEE 802.11b
IEEE 802.11g
IEEE 802.11n
5.1.4
Service Sets and SSIDs
Each wireless network, including all the devices that comprise it, is known as a
Service Set.
NOTE:
Depending on its capabilities and configuration, a single wireless access
point may control multiple Service Sets; this is often done to provide different
service or security levels to different clients.
Each Service Set is identified by a Service Set IDentifier (SSID). This is the name of
the network. Wireless clients must know the SSID in order to be able to connect to
the AP. You can configure the CGNM/ CGNM-3552 to broadcast the SSID (in which
case, any client who scans the airwaves can discover the SSID), or to “hide” the
SSID (in which case it is not broadcast, and only users who already know the SSID
can connect).
