Line Rate (con’t) | Note: The high line rate transmission is enabled |
| with the standard video card (version 1.43 and up) |
| or with the Video+ card. The line rate of incoming |
| ISDN/H.323 calls can be automatically detected |
| and the participant can be connected according to |
| his/her capabilities, without prior setting of the |
| endpoint’s line rate during conference setup. In |
| such a case, the conference Line Rate is the |
| maximum rate for the participant connection. For |
| more details, see MGC Manager User’s Guide |
| Volume II, Chapter 1. |

Audio Alg | Select the preferred audio algorithm. The available |
| audio algorithms are: 8 (G.729/G.723.1), 16 |
| (G.728/Siren7), 24 (Siren14/G.722.1/Siren7), 32 |
| (Siren14/G.722.1/Siren7), 48 (Siren14/G.722/ |
| G.711), 56 (G.722/G.711), or 56 (G.711). |
| Siren 7 and Siren14 are Polycom proprietary audio |
| algorithms. Siren14 can be used only if the MCU is |
| configured to Wideband. |
| To support Siren14, The system must include: |
| • The appropriate Polycom settings to support |
| Siren14. |
| • An Audio+ card must be installed in the MCU. |
| If the conference is set to Siren14 and the |
| endpoints cannot connect in Siren14, G.722.1 is |
| used instead. |
| The option 8 (G.729/G.723.1) is available only in IP |
| Only (VOIP and video) conferences. |
| In Video Switching conferences, all of the |
| participants must use the same audio algorithm. |
| Participants with endpoints that do not support the |
| algorithm selected for the conference are |
| connected as Secondary (Audio only). If the |
| conference line rate is set to 2B or 128 Kbps, to |
| achieve the best audio and video quality select the |
| appropriate audio algorithm for all the participants |
| in the following order: G.728, G.722, G.711. |
