H221 can be used from 64k to 256k on MPEG 2, 3 and 4 modes.
CDQ / H221 can be used up to 256k when interfacing with a Tokyo/Mayah product
Layer 3 Bonding will operate at 128k in MPEG L3 to another unit supporting L3 bonding and most

Note:
It is not possible to change to an audio profile which uses H.221 or CDQ/H221 as an IMUX
mode during an active call. You must hang up and remake the call if you wish to change Imux
Modes.
You will now be asked if you want to save the audio profile (algorithm, bitrate, mode) you have just created.
Saved audio profiles can be used as shortcuts in other menus when you need to select and algorithm, rate and
mode so it is a good idea to store frequently used combinations. If you elect to save the profile you will be
prompted to select an entry in the profile list (there are 25 possible entries in the list) and to enter a name (see
section 4.4.1 Keypad). Using a meaningful name will make it easier to locate the profile later.
