The ADSL equipment produced by Harbor Network Co., Ltd provides the
The channel working mode is determined by operators basing on the demands of users, and for those users who have high requirements for delay such as VOD, interactive games and conference call; for such services as Internet accessing and data downloading, it is recommended to use the interleaving mode.
The related parameter setting is described as follows:
Upon meeting the requirements, the upstream/downstream interleaving delay can be adjusted in ms, with the range of 0 to 255, and its default parameter configuration is: 24ms for downstream and 16 ms for upstream.
The
The default configuration for the upstream/downstream maximum noise margin is 31db, in the case of good line situations, this parameter can be lowered to achieve the goal of reducing the transmission power.
The default configuration of the target noise margin is 6db, and to lower the value of the target noise margin, the synchronization rate of the subscriber line can be increased. Change is not recommended.
The minimum connection rate for upstream and downstream is 32Kbps, it is strongly recommended to keep it unchanged. If this value is too high, some lines may not be connected or connected unstably, especially when the distance of the line exceeds the 3km subscriber line.
The maximum upstream/downstream connection rate is an optional value with the range of
The default value of the minimum training noise margin is 0dB, it is strongly recommended to keep it unchanged.
