have project consists from main office and nine remote sites will be connect through satellite links i am thinking to use Frame relay Hub ans spoke i will use Cisco routers, but i have problem , bcz i am using Satellite link; at the main office there will be one modem for transmit from the main office to remote site with big carrier(9 Mhz) and plus nine modems(1 Mhz) for the receiving from nine sites.
and in each remote site there will be only one modem but the problem how can i configure all 10 modems (1 transmit +9 receive )at the main office in the Cisco router in the main office
to do the frame relay network
i will use star topology that i mean in the HQ or the hub i will use one big carrier for all the nine sites in certain frequency (F1)
and the hub will receive from the nine remote sites at different frequencies (F2,f3,f4,f5,f6,f7,f8,f9,f10) to demodulate these carriers i need nine modems , these modems will connect to the router in the hub ; these modems use interface called smart serial. in the remote site i have only one modem this will be used for transmit and receive for certain freq. frequency (F1 for the receive and one of the these freqs. f2,f3,f4,f5,f6,f7,f8,f9,f10) for transmit
we are planing to use this network for data like oracle , mail and web traffic
as backup for terrestrial network
