Comment

This course is a compress version of RN2812 and RN2817.principle of BSS will cover in review level

General O&M of BSC3i (660/1000/2000) and Flexi BSC are similar. Therefore, testbed of BSC3i (660/1000/2000) or Flexi BSC can use for this training. However, if practical need to focus only Flexi BSC please indicate in training requirement.
