[cisco-voip] VIC2-1MFT-G703 and VIC2-1MFT-T1/E1

[Syed Khalid Ali]

After reading the data sheets I was able to put out theses
differences. Can any one validate!

MFT-T1/E1 does framed E1 (31 timeslots @ 64 Kbps) and fractional (n<31
timeslots @ 64 Kbps) and T1 support.
MFT-G703 additionally does unframed (2048 Kbps) and no T1 support.
Both support the dedicated echo cancellation daughter module EC-MFT-32 or 64.
With MFT-T1/E1 there is no need for external CSU/DSU when used as a T1 module.
Drop and Insert capability.
Supported in 1841 and higher ISR series routers.
Supported with 2600, 2600XM, 2691, 3660, 3700 and higher models.

The NM-xCE1T1-PRI does not support dedicated echo-cancellation card.
Supports with framed and unframed E1 signaling no need for another G.703 card.
No Multiflex operation.
Compatible with supported V.92 modems.
Supports (native) termination of balanced (coaxial) cable.
Simultaneous support of T1 and E1 operation on the same NM-module.
Supported in 2600XM and onwards.
Online insertion and removal (OIR) supported on Cisco 3660, 3745 and
3845 routers.
On-board expansion slot for future usage.

One thing that still confuses me that in case of VWIC2-2MFT-T1/E1 can
one port act as a T1 and other as E1.

Any other thing that someone wants to add!!!
