Hello,
I am a beginner. I’m trying to understand how to set up a LAN/WAN combo. I want to set it up as economically as possible with no real worry about future expansion. I’m playing around with a concept that includes several different offices in major cities separated by hundreds of miles that have different requirements for volume of data transfer to the main server. There are four outlying offices that connect to a server in the main office where there are about 15 users. One office only needs a transfer rate of about 28Kbps, so the capacity allowed by a V.92 dial up modem would seem to suffice. Another needs nearly 100 Kbps – I thought this would just about match the total capacity of an ISDN BRI line (128 Kbps)with ISDN modems. Another needs about 38 Mbps. This would be close to a T-3 at 44.736Mbps with t-3 CSU/DSUs. The last one needs about 1Mbps. This seems to call for a T-1 line at 1.54Mbps with t-1 CSU/DSUs.
Additionally, the lan system in the home office should support all 15 users with printing services and full duplex at 100Mbps on the same server. This seems to warrant 100Base-TX with a concentrator(s) that will also support the network printer.
My questions are: First, are the ideas I have about the lines connecting the outlying offices to the server valid? If not how should they be set up?, and second, if they are valid, what is the best way to funnel all of the various data flows from the outlying offices into the server in the main office. Or, am I way off base?
Thanks in advance for your insight.
