Question : REAL WORLF FRAME RELAY BASIC SETUP

I like to know about real world frame relay basic setup .

Suppose that we have main office in USA , 2 branches at  Korea and Singapore .

At USA main office , we subscibe the FRAME RELAY service from USA's service provider .
At USA , we have to apply for T1 line installation at USA office plus "purchase" the some number of the PVC with specific bandwidth .

We want the communication between USA, Korea and Singapore are bi-direction , all these 3 locations can communicate with each other .

Only subcribe partial MESH . Japan and Korea are no direct connection . USA's office router is act as "hub router" and Japan & Korea routers are act as "spoke router" .


Question1 :
Do we need to install T1 line at Korea or Singapore sites ??

Question2 :
Do we need to subscribe Frame Relay from Korea/Singapore 's service providers ?

Or just subscribe from USA service provider will take care the whole setup ? ( assuming that service provider in USA does not has office in Korea neither in Singapore )

Question3 : might ask later after first 2 questions beeing answer .

Answer : REAL WORLF FRAME RELAY BASIC SETUP

1) You will need a "local loop" at each location. This is the leased line that connects your office to frame-relay providers point-of-presence (POP) at that location.  The speed of these local loops will be based on the service (port speed, CIR) that you obtain from your frame-relay provider.

2) If you are not obtaining frame-relay service for all locations from the same provider, you will need to arrange for a "network-to-network" interface (connection) between the different providers involved.

>Or just subscribe  from USA service provider will take care the whole setup ?

That would definitely make your life easier.

But here's the catch. Frame-Relay is a... fading technology. New installations have dropped significantly. And some frame-relay providers are not offering frame-relay to new customers. If you're an existing customer and you want to ADD new sites, they'll accommodate you.  But if you are a new customer, you can not get a new connection.

The trend these days seems to be towards MPLS for private multi-access networking.
