If the endpoint uses the built-in MCU to initiate a conference, no external MCU is required.

HUAWEI TE40&TE50&TE60 Videoconferencing Endpoint Administrator Guide 4 Conference Experience Issue 01 (2014-12-23) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 20 MCU As an indispensable component in a multipoint conference, the MCU is responsible for multiple functions, such as site access, video exchange, audio mixing, data processing, and signaling interaction. Built-in MCU An endpoint with the built-in MCU function can initiate a multipoint conference by implementing functions such as site access, video exchange, audio mixing, data processing, and signaling interaction. The endpoint can work independently, without involving the other components on the videoconferencing network in conference scheduling. In this case, the endpoint functions as a mini MCU.  On the endpoint web interface, choose Maintenance > System Information, and check whether the endpoint has a built-in MCU.  To provide the built-in MCU function, the endpoint requires a specified license. Contact Huawei post-sales engineers to purchase the license. Conferences held with the built-in MCU function have the following features:  After a point-to-point call is set up, site-by-site calls can be made to hold a multipoint conference.  BFCP or H.239 presentation dual-stream conferences are supported. A SIP site supports BFCP dual-stream, an H.323 site supports H.239 dual-stream, and a hybrid conference supports both BFCP and H.239 dual-stream.  Conferences can be locked from the built-in MCU. After a conference is locked, calls from new sites are restricted.  Conferences can be attended by both H.323 and SIP sites and support H.323 site control.  If a conference is held with a built-in MCU, only Presentation is available. Built-in MCU Capabilities of TE40/TE50 The built-in MCU supports the access from six HD video sites and three audio-only sites simultaneously in a conference.  The six HD video sites include the local site that uses its built-in MCU, that is, the built-in MCU site.  A maximum of six 720p30 full-adaptive sites are supported.  G.722 or G.711 full adaptation is supported. Built-in MCU Capabilities of TE60 The built-in MCU supports the access from nine HD video sites and three audio-only sites simultaneously in a conference.  The nine HD video sites include the local site that uses its built-in MCU, that is, the built-in MCU site.  A maximum of nine 720p30 full-adaptive sites are supported.  G.722 or G.711 full adaptation is supported.

HUAWEI TE40&TE50&TE60 Videoconferencing Endpoint Administrator Guide 4 Conference Experience Issue 01 (2014-12-23) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 21 Initiating a Multipoint Conference on the endpoint with a Built-in MCU Before initiating a multipoint conference, you must enable the built-in MCU function. To do so, choose System Settings > Conference > Normal and set Multipoint call mode to AUTO or Built-in MCU. To initiate a multipoint conference using the built-in MCU, call the first site and then place calls one at a time to several other sites. For details about other methods for initiating a multipoint conference, see 4.2.2 Initiating a Conference from the Predefined Conference Page, 4.2.3 Initiating a Conference from the Conference History Page, and 4.2.4 Initiating a Conference from the Address Book Page. For example, to use the built-in MCU of endpoint A to initiate a conference that includes endpoints A, B, C, and D, perform the following steps: From endpoint A, call endpoints B, C, and D until all the calls are set up. If the built-in MCU of an endpoint is used during a conference, Lock conference can be selected from the Conference control screen on the endpoint whose built-in MCU is being used to prevent unwanted additional sites joining the conference. Conference Control Three types of roles exist in a multipoint conference initiated using the built-in MCU: Endpoint to which the built-in MCU belongs, chair site, and non-chair sites. A site can request chair control rights only after chair control is enabled on the Endpoint to which the built-in MCU belongs. The chair control is enabled by default. Only H.323 sites support conference control functions. Table 4-4 Conference control in a multipoint conference initiated using the built-in MCU Role Conference Control Endpoint to which the built-in MCU belongs Enable chair control, Disable chair control, Lock conference, Set Continuous Presence, and Recording Chair site Release Chair, End conference, Delete Site, Add site, Set Continuous Presence, and Recording NOTE Only H.323 sites where the endpoints in V100R001C10 are used support the Conference Video Layout and Start functions. Non-chair site Request chair The recording function is available only when the recording server address is configured on the Endpoint to which the built-in MCU belongs. Continuous Presence on the Endpoint to Which the Built-in MCU Belongs The Endpoint to which the built-in MCU belongs adjusts the continuous presence layout based on the number of sites in the conference, and can add the local video and presentation

HUAWEI TE40&TE50&TE60 Videoconferencing Endpoint Administrator Guide 4 Conference Experience Issue 01 (2014-12-23) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 22 to continuous presence.

HUAWEI TE40&TE50&TE60 Videoconferencing Endpoint Administrator Guide A E1 and T1 Grounding Criteria Issue 01 (2014-12-23) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 178 A E1 and T1 Grounding Criteria Read the following grounding criteria carefully and comply with the relevant requirements during the installation of the endpoint. The grounding design of the telecom office (station) follows the principle of equalized voltage. That is, the work grounding and the protection grounding (including the shielded grounding and the surge protection grounding of the distribution frame) share a set of grounding conductors. When the E1 cable of the cabinet is over 7.5 m and the T1 cable of the cabinet is over 10 m, a shielded cable and a shielded connector should be used and grounded. When the E1 interface is connected to other devices using coaxial cables, the external shield layers at the transmitting endpoint and receiving endpoint should be connected to the protection ground at the same time. The dual in-line package (DIP) switch offers the possible disconnection function at the receiving end. Copper-core materials instead of aluminum materials should be used for the ground cable. The plastic insulated copper wires with yellow and green insulation color should be used for the protective ground cable. The protective ground cable should not exceed 30 m, and the shorter the better. When the protective ground cable exceeds 30 m, the ground bar should be rearranged. In a balanced circuit, the joint of the E1 (T1) cable and the connector should be grounded using the external shield layer (the grounding conductor) or an additional wire to ensure normal reception and transmission in each E1 (T1) channel. In an unbalanced circuit, the metal braid shield layer of the cable should be seamlessly connected to the coaxial connector. When the E1 cable exceeds 30 m and the T1 cable exceeds 40 m, use the multi-point grounding mode. In addition, connect the E1 cable to the ground at every 15 m and the T1 cable to the ground at every 20 m. When the E1 or T1 cable is extended out of the office (station), the E1 or T1 cable should go through the main distribution frame (MDF) attached with the security unit. The shield layer of the E1 or T1 cable should be firmly connected to the protection ground of the MDF. The security unit on the MDF should have the overvoltage protection, overcurrent protection, and failure alarm functions. The maintenance personnel should check the equipment periodically and replace the ineffective protection unit in time. For questions about grounding the device, contact the device provider for technical support.
