How can I configure the clock synchronization between two ViewPoint 8650 MCUs that are cascaded through the E1 line?

Conferences held on the MCUs with asymmetric continuous presence layouts cannot be cascaded.

The ESN cannot be queried in the BootROM system of the ViewPoint 8650 MCU.

The board with video or audio functions cannot be inserted into GPUA in slot 9 of a ViewPoint 8660 MCU.

1. Capacity expansion involves participant capacity, conference IP resources, continuous presence resources, and adaptation resources for software and hardware. You must expand capacities for the software and hardware at the same time; otherwise, the MCU will generate an alarm. Hardware capacity expansion is to add GPUA service boards or HDPX high-density daughter boards, and software capacity expansion mainly involves license capacity expansion. 2. To expand capacity, contact technical support engineers of local Huawei offices to have them calculate hardware resources required for corresponding license resources using the quotation template. Then add required hardware resources. You also need to sign a capacity expansion contract with the local office or an agent before capacity expansion.
