New Features
IGMP version is now selectable (V2/V3) in the Advanced Setup/LAN menu. This setting
pertains to IGMP Proxy (WAN) in router-mode only.
Changes and Fixes
Fixed an intermittent DNS relay issue where the connected LAN-side DHCP client
would receive the modem’s own LAN IP as the DNS server instead the DNS IP
received from the network
TR-069 field InternetGatewayDevice.DeviceInfo.ModelName now shows actual model
name instead of board ID
Fixed that LAN Statistics wouldn’t increment when Virtual Ports feature was enabled
Fixed a compatibility issue with P2P tool (ARES) running over an IPoA PVC
Changed the TR-069 function InternetGatewayDevice.DeviceInfo.UpTime to start
when SNTP is set and synced
Modified TR-069 parameters for firewall and IGMP
Fixed Boolean logic issue with ClearAccess ACS
Changed TR-069 attribute WANPPPConnection.n.Enable from true/false to 1/0
Status of LAN port 4 can now be read via TR-069
Added a TR-069 VLAN MUX (802.1q) parameter
For static DNS entries, the modem will provide its LAN IP (ie: 192.168.1.1) to LANside devices. When “obtain DNS server addresses automatically” is selected, the
modem will pass the DNS IPs it received from the WAN interface to LAN-side device
Moved Enable Full Cone NAT menu selection option directly underneath Enable NAT
Revised the APUSER account by removing the ability to do software upgrades

Anomalies
ATM statistics don’t increment
Eth0 appears as an interface in the initial port mapping menu
SIP ALG needs to be set to 5060
The password for “apuser” cannot be changed
Compatibility/System Notes
This release is backwards compatible with all versions listed in the revision summary.
For modem management purposes, a PC connected to a LAN port and using a static IP
address should be configured for 192.168.1.3 or higher. When the modem is configured
as a DHCP server, the first address it issues will be 192.168.1.3. This is because the
modem reserves two addresses (one for each CPU). If the primary address is changed
from its factory default 192.168.1.1 to, for example, 10.10.10.1, the secondary address
will follow automatically (10.10.10.2).
This particular release supports Physical Layer Retransmission (PhyR) which operates at
Layer 1 and uses a mechanism similar to TCP where retransmits occur if errors are
detected. As a result the line is more robust (greater BER) while also allowing the INP to
be set lower, thereby increasing the available data rate. PhyR is not configured on the
modem but is negotiated automatically during the initialization process with the DSLAM
(Broadcom proprietary). Versions supporting PhyR can be identified by the number 3 in
the third character of the file name (example: H131-310CTU -C07_R01_4.5.5.27).
Normally the modem operates using two pairs, however when configured for nonbonding mode, the WAN connection is via the 2nd pair only. The 2nd pair uses the outer
pins on the modem’s ADSL connector (RJ-14 positions 1 and 4) and corresponds to the
front-panel ADSL2 LED. Statistics for the 2nd pair can be seen at 192.168.1.2 or the
modem’s primary management IP address plus one.
IGMP Standard and Blocking modes apply only in instances where multicast traffic is
present without a set top box first generating a join message. This condition is unlikely to
occur since there’s little reason for unsolicited multicast traffic to be present. However, if
for some reason it is, in standard mode, multicast traffic will flood to all bridge ports
(even if IGMP snooping is enabled) and in blocking mode, multicast traffic will be
blocked. The purpose of the Enhanced IGMP feature is to prevent STBs from receiving
IGMP reports from other LAN-attached STBs so as to ensure they’ll always send IGMP
report and leave packets even if watching the same channel.
MAC address considerations - Each modem contains a label indicating its LAN (base)
MAC address. The source MAC address contained in upstream packets equals this
address +3. Example: a CT-5631 with a base MAC ending in AA:10 will assign AA:13
to its 1st PVC. Additional PVCs will increment by one. This rule applies to bridge and
routed PVCs alike. In the case of TR-069, the modem’s base MAC address will be used.

Wireless security - Each modem’s factory-default wireless settings consist of a unique
SSID and WEP key. The SSID is Comtrend plus the last 4 characters of the modem’s
Ethernet MAC address (example: Comtrend741b). Network Authentication is Open and
64-bit WEP encryption will be enabled using a Network Key derived from the last 10
characters of the MAC address (example: 1d200c741b). This feature is enabled by
default and can be disabled or changed as desired.
In the current software revision, the DHCP Option 60 Vendor ID for Comtrend modems
is “uDHCP 0.9.6”.
Port Mirroring – All Comtrend modems contain a troubleshooting/debugging aid called
port mirror which makes it possible to monitor WAN traffic from the LAN using
Wireshark or other tools. Incoming and outgoing traffic can be monitored separately or
simultaneously from LAN port 1 or the USB port (where applicable). For more
information on using this feature contact your Comtrend rep.
Historical
H131-310CTU-C06_R02_4.5.5.22
The backup configuration filename has been changed from backupsettings.conf to
version_name.conf. The name of the backup file will reflect the software revision
resident on the modem (example: H131-310CTU-C06_R02_4.5.5.22.conf). The file
name can be modified but should be preserved if the need arises to email it to Comtrend
NAT is now enabled by default for PPP connections
MTU value settings shall be restricted to 64-1500 (PPPoA) and 64-1492 (PPPoE)
Hide login passwords when selecting view source in GUI
If excessive PADI packets were received on the WAN interface, the modem might
lockup over time. This condition was seen with the Calix E5 only
SSID names are legible in the port mapping menu
Corrected reset-to-factory default condition when WEP encryption was enabled and two
or more WEP network keys were configured
Fixed issue where wireless was enabled and wireless security was set, modem was
unable to apply configuration changes it received from a Comtrend ACS
Removed a previous modification forcing the modem to respond with an ACK to each
FTP port command as this created a general LAN to WAN FTP issue. The original
modification was required in only one known scenario, namely an FTP session from the
modem’s LAN to the management port of a Calix C7
Fixed issue where PPPoE sessions wouldn’t always reconnect after DSL retrain if the
modem received excessive PADO packets from multiple broadband remote access
servers
H131-310CTU-C05_R01_4.5.5.22
Gratuitous ARP - In cases where the modem contains a static IP (i.e.; MER), this
feature generates traffic enabling upstream equipment to populate its MAC table
“Save Default configuration CLI Command”. This allows the user to manually create
their own factory default settings on a per modem basis. This is accomplished by simply
H131-310CTU-C07_R01_4.5.5.27
Comtrend Release Notes

using the modem’s GUI to create the desired configuration (save/reboot) then telnet to
the modem and issuing a save command as such; save_default --save (space between
default and the two dashes). There are also commands for clearing and reading the
default settings; save_default --clear, save_default –read
New modem management privilege level restricting menu access to changing the WiFi
settings, software upgrades, configuring/viewing logs, running diagnostics and viewing
all stats. This restricted GUI is accessed with the user name and password “apuser”
(user name and password are case sensitive)
Slave ADSL statistics are now available
Modem now responds with an ACK to each FTP Port command
Changed IGMP Snooping from polling to interrupt (Fast/Immediate Leave) so a port is
removed immediately from a multicast group after a Leave Group message is received
Port Mirroring responds bi-directionally
DHCP Option 125 supports TR-111 (device identity is sent to the network)
Modem reports the most recent 32K of its system log to an ACS
Remote access can be enabled/disabled using the CLI
Removed the PORT selection in Advanced Setup\WAN since this applied to VDSL2
When configuring Virtual Server with a range, default ports such as 23 and 80 will be
shifted accordingly
“PPPoE persistently dialing” added to PAP mode
Blocking, instead of Standard mode, is now the IGMP default setting
H131-310CTU-C04_R01_4.5.5.19
Added PhyR-related statistics
Unique SSID and WEP key for each wireless modem: (SSID = Comtrend plus the last 4
characters of the Ethernet MAC address. WEP with 64-bit encryption keys equal the
last 10 characters of the MAC address) - enabled by default
Telnet/SSH to WAN or LAN
Can disable Full Cone NAT without having to delete the PVC
In Routed Mode (MER, PPP, IP) the modem will assign a DHCP lease time of 24 hours
regardless of PVC status
Upgraded to the latest PhyR DSP
