I am getting ready to switch Frame Relay providers. I have three sites, each with a CISCO 1750 router. The Head End also has a PIX 506. Each router has a WIC 1DSU T1 interface card installed in SLOT0.
Currently, the circuit speed at the head end is 128k and each remote location has a 64k circuit. When I change over the Head End will stay the same but the two remote sites will go to 56k. My Service Provider swears this is not a switched 56k circuit but a dedicated 56k circuit.
My questions are:
1. Do I need to get the WIC 1DSU 56k4 interface card for the two remote loacations.
2. If I do need the card, can I just drop them in SLOT1.
3. I do have to change the DLCI's on the remote routers as well but that's not really a problem. I do wonder about the service module timeslots however. They currently read:
service-module t1 timeslots 1-2
A very knowledgable individual told me they will need to be changed to:
I believe that service-module t1 timeslots 1-2 is configured on the HUB router (Head End) ... on the remote it may say.. service-module t1 timeslots x.. on that command you can add the speed 56 and you will try to establish a connection at 56k.. I think you can use the same wic-cards.. As long as you match the speed.. You will be up and running..
