The size of this buffer SHOULD be locally
configured to allow accommodation to the PSN-specific
packet delay variation.
If configured to a value not supported by the
implementation, the agent MUST return an error code
'jtrBfrDepth' in 'cpwCTDMConfigError '.
Jitter buffers are a limited resource to be managed.
The actual size should be at least twice as big as the
value of cpwCTDMCfgJtrBfrDepth
