RE: Difference Between T1 & Frame relayTo clarify, T1 (or better still, DS1)
is a Physical Layer standard which regulated line encoding and bit timing.
Frame Relay is a Data Link Layer framing convention (based on a modified
HDLC) and has nothing to do with the Physical Layer bit timing and line
e
Briefly,
T1 is a layer one specification describing a digital, point to point
circuit made up of 24 64k channels, each with 8k of inband signalling. The
aggregate as many has mentioned is 1.544Mb/s
Frame Relay is a layer two specification describing a packet switched
network.
The confusion li
T1 is layer 1
Frame Relay is Layer 2. It has datalink addressing (DLCIs).
Frame relay runs over T1 (and other things like 56K DDS and DS-3).

Title: RE: Difference Between T1 & Frame relay
T1 is a type of connection to an ISP, ex. 56k, ISDN, T1, T3
Frame-Relay is an encapsulation connected to a telco provided frame-relay cloud
frame is run over T1
T1 is a permanant connection to an ISP
frame can either be pvc (perm
Hope this helps. Holler back if you need more. I looove Frame! =)

Frame Relay refers to the data network that your provider uses to get data
from one endpoint to another. Inside their frame relay cloud, they usually
run ATM, but that's another matter entirely.
T-1 is a digital line that is used to access the frame relay network. so,
you have this:
Router --
Can some one clearly explain the difference between T1
and Frame relay, Does T1 run over Frame relay circuits
? Aren't they both Layer 1 in the OSI model.
I have searched the archives and found some good info
but I am still a little fuzzy about the concepts.
Thanks Guys.
