CHAPTER 2. MMC Programming2-356 Samsung Business Communications(continued)No Parameter Description Default12 JITTER AP The Adaptation Period controls the speed at which thejitter buffer can adapt downwards when currentnetwork conditions allow. The larger the value, theslower the jitter buffer adapts down, when jitterdecreases. The value is programmed in milliseconds,with a default of 10000ms(10seconds) and aminimum value of 1000ms(1 second).1 sec13 JITTER AT When the jitter buffer grows past the DeletionThreshold, frames exceeding the deletion threshold aredeleted immediately. Audio quality may be negativelyaffected. This parameter is expressed inmilliseconds, and may be programmed from the valueof the DelayMax up to 500ms.The range is 150 ms ~ 500 ms.250 ms14 T38 FAX USE This option selects the mode of FoIP. If selct Enable, faxprotocol is T.38. In other case, fax protocal is G.711pass through. (This mode should be use G.711 codec)Enable15 T38 REDUND. This option selects retry count of Fax-over-IP if errorsare detected. The range is 0~3(0 means no retry).316 FAX ECM This option selects retry of Fax-over-IP if errors aredetected.ENABLE17 MAX FAX CNT This is the maximum number of channels that can besimultaneously used for Fax-over-IP. The range is00~04.218 RTCP PERIOD This option selects the interval time for sending RTCP. 5 sec19 TOS/DifServ An 8-bit binary value that will be used by externalrouters, switches, etc,(that optionally support TOS-bitprioritization) to identify the transport-priority value ofdata packets generated by the MGI card. This value canbe left at the default value(00000) if your networkinfrastructure does not support this method ofbandwidth management.All bits 020 802.1 p/q Each created channel may be given its own Ethernetheader provided that the Comcerto MAC address isunique. When sending a payload Ethernet frame, eachchannel uses its own Ethernet header (if it has one).This option is enable or disable for 802.1 p/q.(including 802.1 VLAN and 802.1 Prriority)NOTE : These options apply to RTP/RTCP.Disable21 802.1 P Set the 802.1 priority. The range is 0~7. 022 802.1 VLAN Set the VLAN tag. The range is 0~ 4095. 0
