Difference in T3 (full rate and subrate)

CHRIS KALETH · ‎10-24-2007

We are ordering a frac 22MB DS3 and need to order a new router and WIC card. I know what WIC card we need but am confused on the router side. What is the difference between full and subrate. I don't want to spend the money for the 3825 if we can get by with a 28xx router. We will primarily only sending traffic to our MPLS provider.

2800 supports one T3 module and hence you should be ok to go with it.

The above data seems to be more from a marketing perspective where it is stated that the router would not support wire rate performance for a full T3 link.

We have a DS3 terminated on a 2800 and its working absolutely fine
