Need advise NIM-2MFT-T1/E1 and NIM-2CE1T1-PRI or NIM-4MFT-T1/E1

I am building a new router configuration to upgrade our 7204 and need advise to make sure I pick the correct T1/PRI card..

We currently have two PRI and two T1 in production. 

The new router is a ISR433.

Now, I am having a hard time picking the right card compatible with our two in production PRI and two T1 configuration.

I can see two types of the 4th Gen NIM-2MFT-T1/E1 and NIM-2CE1T1-PRI (See picture below)

The first one is "clear-channel data", the second one is "channelized data".

Per my current router PRI configuration, do I need to get the channelized card or I can still get the clear-channel data card and will be able to clone the config? The reason I ask, it's because if I don't need the "channelized data" card I could get the NIM-4MFT-T1/E1 that has four ports and configured both PRI and T1.

This is some of the PRI config:

controller T1 2/0
framing esf
linecode b8zs
cablelength long 0db
pri-group timeslots 1-24
!
controller T1 2/1
framing esf
linecode b8zs
cablelength long 0db
pri-group timeslots 1-24
!

interface Serial2/0:23
description PRI Circuit
no ip address
encapsulation hdlc
isdn switch-type primary-ni
isdn incoming-voice voice
isdn outgoing display-ie
no cdp enable
!
interface Serial2/1:23
description PRI Circuit
no ip address
encapsulation hdlc
isdn switch-type primary-ni
isdn incoming-voice voice
isdn outgoing display-ie
no cdp enable

voice-port 2/0:23
input gain -2
output attenuation 2
echo-cancel coverage 32
!
voice-port 2/1:23

output attenuation 2
echo-cancel coverage 32
!

Thanks!

NIM-2MFT-T1/E1 is all you need for a PRI.

Chris I understand the big difference is that NIM-2MFT-T1/E1 does not support G.703, on another hand NIM-2CE1T1-PRI does support G.703, is that correct?
