Troubleshooting DTMX5000 IP Gateway
5–6 Rev. 1
5.2.3 The Gateway Does Not Reply to Telnet but Does Reply to SNMP
and Terminal Communication
Possible Cause Solution
High CPU Load. This situation can occur
when the Gateway is highly loaded –
high bit rate with small IP packets. Use SNMP to check the CPU load.
5.2.4 A User Cannot Receive Multicast Channels or Loses Multicast
Packets
Possible Cause Solution
Multicast is disabled or the Multicast
channel is not registered. Check that Multicast is enabled and that the specific Multicast
Channel is registered.
QoS maximum bit rate is too low. Check QoS parameters for Multicast channel.
If Multicast is enabled, then the Gateway assigns the maximum
bit rate of 2 Mbit/s for each.
If the user consumes more, packets will be lost.
5.2.5 A PC Connected to a LAN Fed by a Satellite Receiver (Static
User) Does Not Receive Unicast Transmissions
Possible Cause Solution
The receiver is not functioning. Check whether other PCs on the LAN can RX Unicast. Check
the status reported of the receiver.
No network connection between the LAN
and the satellite receiver machine. Check the local LAN connections by pinging from the client to
the receiver.
Incorrect static user settings. Check that the static user settings are set to unicast rather than
Multicast and change if necessary. In the Static user definition
ensure that the PC is in the subnet.
5.2.6 The CCU Cannot Register a User in the Gateway
Possible Cause Solution
The user is already registered as a Static
User. Check the users table to ensure that the user is not registered as
a Static User.
