Re: Max Supported T1 & T3 on ISRs

Though it is recommended to run 4 x T1/E1's on a 2800 series due to CPU limitations , you can actually install 6x 2port modules

THe 2800 supports one T3

The 3825 supports 14 T1/E1 modules and 1xT3/E3 module while the 3845 supports 24 T1/E1 modules and 2 x T3/E3 modules

The 1800 series does not support the T3/E3 module and can take 2x 2port modules in its 2 wan slots
