Appendix G MN/CDM570L.IOM
G–13
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 Re
mote 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:
Service Description VLAN ID Sites in Service
Shared Voice Services 0911 A, B, C
Shared Internet Services 1111 B, C
Management Services 1200 A, B, C
Corporate Network ‘A’ 0080 A
Corporate Network ‘B’ 0081 A, B
Corporate Network ‘C’ 0090 B
Corporate Network ‘D’ 0100 C
Corporate Network ‘E’ 0101 C
