H11-861_V4.0 HCIP-Collaboration V4.0 Questions and Answers

In a co-deployed small/medium network, LAN1 is used for the default gateway to the SMC/public network; LAN2 serves the private segment, so you do not set LAN2 as the default routing port.

4CIF (704×576) at 30 fps gives 704 × 576 × 30 ≈ 12.17 million pixels/s. At 48 bits per pixel, that’s 12.17 M × 48 ≈ 584 Mbit/s, which is nearest to 600 Mbit/s.

When cascading an old-architecture MCU with a new-architecture MCU, only the proxy channel on the new side consumes bandwidth and codec resources - the legacy MCU’s cascading channel is not used.

System administrator accounts in the SMC are management-only and do not support binding to endpoints for use as conference-joining devices; endpoint binding applies only to conference user or room accounts.

If the input volume falls below the echo canceller’s detection threshold, the device can’t identify and suppress return audio, leading to echoes or squealing.

An audio loop, where output is fed back into the input, directly causes echo and feedback noise.

Placing the microphone too close to the speaker allows direct pickup of its output, resulting in echo and potential high-pitched feedback.

Uncompressed 1080p at 60 fps has 1920 × 1080 = 2,073,600 pixels per frame. At 24 bits per pixel, that’s 2,073,600 × 24 = 49,766,400 bits per frame. Multiplied by 60 fps gives 2,985,984,000 bit/s, which is approximately 2986 Mbit/s.
