2 WebUI Access Overview
This section explains the various access interfaces and access levels to CGA4131 Web UI.
There are 3 interfaces for the user/operator to connect to on the CGA4131 TCH2-GA-TBR:
• LAN (Default URL 192.168.0.1 on LAN side)
• Cable Modem (CM IP on the WAN side)
• eRouter (eRouter IP on the WAN side)
Apart from these 3 interfaces, there are 2 user levels – Home User and Advanced User.
The access to the various Web UI pages from various interfaces are determined by the configuration of specific MIBs and the bit masking MIB to enable or disable a specific Web UI page. The following table explains the Web UI pages accessible in these combinations:

The Web UI pages available for home user and the advanced user access levels can be different. They are defined by the access Level MIB and bit masking MIBs (tchCmWebAccessHomeWriteBitmaskand tchCmWebAccessAdvancedWriteBitmask).The bit masking information is also stored in the config file. They can also be modified by the SNMP MIBs. Please see Appendix 2 for examples of configuring these bitmask MIB elements.
The user is directed to login page to login with default system credentials (admin / password). For the advanced user, the user name is admin and the password would be the generated password of the day (POTD).
CM Config file snippet for POTD configuration
SnmpMibObject tchCmWebAccessAdvancedType.0 Integer 2; /* potd */ SnmpMibObject tchCmWebAccessAdvancedPassword.0 HexString 0x272a73bdb4945eddc88f6a66198c1056;
The Web UI has an idle timeout of 15 minutes. The user needs to re-login to access the Web UI after the timeout.

3 Initial Configuration and Setup
The CGA4131 is configured using the Web UI.
3.1 Accessing the Web UI
CGA4131 Web UI can be accessed through the various interfaces (LAN IP, CM IP or the eRouter IP) as explained in the previous section. The gateway prompts the user to enter the username and password.
Figure 3.1
The various pages on the Web UI would be accessible once the credentials are accepted.

5.6 DOCSIS Signal
Status Tab / DOCSIS Signal
The DOCSIS Signal page displays the plant information on which the modem is connected. Click on the Status tab then click on DOCSIS Signal.
Upstream Bonding:
This section displays information about RF upstream Bonding, including upstream channel ID, Upstream Lock Status, Channel Type, Centre Frequency, Band Width, Modulation, and Power Level (Tx Power level at gateway for the particular channel).
• Upstream Bonding - Number of channels locked to upstream which can be used for upstream data transfer
• Upstream channel ID - The CMTS identification of the upstream channel
• Upstream Lock Status- Displays Locked if QAM and FEC are locked (indicates that
the channel is usable)
• Upstream Channel Type - Displays if it is a SC-QAM channel (Phy type 3) or a OFDMA channel (Phy type 5)
• Upstream CenterFrequency - The center of the frequency band associated with this upstream interface. Displays 0 if the frequency is undefined or unknown.
• Upstream Band Width-The bandwidth of this upstream interface as configured on the CMTS (Generally 1.6MHz, 3.2Mhz or 6.4MHz)
• Upstream Modulation - Displays the modulation used on upstream ATDMA, TDMA, SCDMA or MTDMA
• Upstream Power Level- Transmit power level at which the cable modem is transmitting on the respective channel
Downstream Bonding:
This section displays information about the RF downstream bonding with downstream channel ID, Downstream Lock status, Downstream Bond Status, Downstream Channel Type, Downstream Centre Freq., Downstream Band Width, Modulation, Power Level (Rx power level at the gateway for the specific channel) and SNR Level.
• Downstream Channel ID-The CMTS identification of the downstream channel within this particular MAC interface. If the interface is down, displays the most current value. If the downstream channel ID is unknown, 0 is displayed.
• Downstream Lock Status -Displays Locked if QAM and FEC are locked (indicates that the channel is usable)
• Downstream Bonding-Number of channels locked to downstream which can be used for downstream data transfer
• Downstream Channel Type -Displays if it is a SC-QAM channel or a OFDM channel
• Downstream Centre Frequency-The center of the downstream frequency associated
with this channel
• Downstream Band Width -The bandwidth of this downstream channel. Most implementations are expected to support a channel width of 6 MHz (North America).
