2CE1B

I have an Cisco 3660 utilizing 1 2CE1B interface and 1 2CE1Unbalanced interface. I want to move the 2CE1Unbalanced interface to an Cisco 3640 and replace it with another 2CE1B in the 3660. What should I be looking for in the 3640 to ensure that this swap will work. The 3640 currently has 1 1CE1B and 1 1CE1Unbalanced interface, I will be removing the 1CE1B to be replaced with the 2CE1Unbalanced.

Re: 2CE1B

The difference between Unbalanced and Balanced it balanced module has 120 ohm and unbalanced module has 75 ohm interface. So you need to make sure that elco deliverd that E1 line accordongly.

Rest is fine as all the ios supports those modules.
