Appendix G
At each CDM-570/L-IP Remote Modem, VLAN Filtering must be enabled and the appropriate
VLAN IDs entered into the Match table.
As shown in Figure G-5 the network consists of a managed Hub Site and three Remote sites. In
this service, Remote Sites 'A' and 'B' share a common corporate service (Service 'B' Network),
a typical requirement in the oil and gas industry. All three sites employ a Shared Voice Service.
Sites 'B' and 'C' employ a Shared Internet Service. Each site additionally has services (VLAN
networks) that are exclusive to that site. The services provided in this network are defined in the
table below:
