A preprovisioned CMA slot can remain empty without conflicting with populated slots. 
Once installed and enabled, the system verifies that the installed CMA type matches the 
configured parameters. If the parameters do not match, the CMA remains offline.
Note: On the E3 CMA, bit stuffing is not supported in G.751 framing mode. All of the 12 
justification service bits and the 4 justification bits contain valid data on the transmitted signal. 
Incoming bitstreams should contain valid data in the 12 justification service bits and 4 justification 
bits, otherwise the link will not function.
