This parameter defines if to use Spaced or Normal CBR. Normal - TD will be allocated from the policing range (described in ACE2002 NMS SRS). The PCR is expanded with a constant value of 30 cell/sec. Spaced - TD will be allocated from the spacing range (described in ACE2002 NMS SRS). The PCR and CDVT will be expanded as described for Normal, and the CES traffic including the OAM will be spaced out at the TD's PCR. This mode is used to prevent CDVT violation due to OAM cell insertion with the CES traffic.
