H.3.4 Dynamic Hub Demodulators in a Multiple TDM Hubs Configuration
Appendix D. OPTIONAL NETWORK PROCESSOR (NP) INTERFACE MODULE
In BPM Mode, multiple Hub TDM Modem configuration is supported along with dynamic
assignment of Hub Demodulators.
In a dynamic Hub Demodulator assignment, the Hub Demodulator can be assigned to any Hub
TDM Modem. Packet transmission should therefore be forwarded from the Hub Demodulator to
the corresponding Hub TDM Modem. In order to accommodate this, a separate VLAN packet
tagging is used.
Packets transmitted from the Hub Demodulator will be tagged with configured VLAN (or double-
tagged if the packet already has a VLAN) and then sent to all designated Hub TDM Modems. The
corresponding Hub TDM Modem(s) will receive and process these packets, while non-
corresponding Hub TDM Modems will ignore them.
Figure H-8. Hub VLAN Configuration HTTP/HTTPS Interface Pages
With this configuration (see Figure H-8), the Hub TDM Modem is set to Vipersat Hub per the
'Admin | Vipersat Mode' web page and configured for Multi-TDM Tunneling Mode per the 'LAN |
Interface' web page (see Appendix D. OPTIONAL NETWORK PROCESSOR (NP)
INTERFACE MODULE, Sections D.2.5.2.1 and D.2.5.4.1).
This VLAN communication is configurable as Automatic. When Multi-TDM Tunneling Mode is
configured as Manual, then a unique VLAN ID has to be entered.
