iDirect 5000 series Satellite Modem/Router

Hi All,

Pls i need information on this series of iDirect satellite modem/router, particularly on the issue of the number of links that this equipment can carry.

Thanks.

I mean supposing it has enough power, can it be used as a hub for other satellite links connected to it?

Secondly what layer 2 protocol does it support?

Thanks Pat but do u know what the proprietary protocol is called?

The protocol is very similiar to Slotted Aloha, but has some significant differences.  

In iDirect proprietary, the payload of each upstream timeslot varies by type of FEC.  For example: at .793 the payload of a timeslot is 392 bytes.  You still have all the TDMA overhead (Unique Word) in the header and trailers and you can also add additional bytes to the Inroute Protocol Structure if you use things such as SAR, PAD, etc.

As for your original question: You have a remote (terminal).  Not a hub.  It is capable of locking onto a downstream carrier and can freq hop in mulitple D-TDMA upstreams to get back to the hub.  For instance, you can lock onto a large downstream carrier (say 6MB downstream carrier) and you might have return channels aka (inbounds/upstreams) configed as 3ea 2048k channels (TDMA, Freq hop) to get you back to the HUB (hence, return channels).  Heck, nothing says they have to be 2048k each.  They could be larger, say 2ea 3MB channels?  The config of your upstreams are dependent on the capability of your terminal and buying the right amount of MHz to support your requirement.
