Time Slot 9 ~ 30 1408k Maximun Data Rate 2048kbps ITU 991.2 (2004) (G.SHDSL .Bis) supports data rate up to 56964Kbps, but G.703 (E1) only supports data rate of 2048kbps so the maximum data rate of SHDSL line, connected with DCEs, depends on data rate of E1, 2048kbps.
Page 57
For fractional E1, FE1, the data rate is from 64k, N=1, to 1984k, N=31, according to the E1 frame. If the E1 frame is FAS or FAS+CRC4, there are 1~31 available time slot for use data. If the data rate of SHDSL line set to be 512k, the time slot number is 8 and first time slot number is 1.

For Annex A and B, the rate can be adjusted in increments of 64kbps from 64kbps to 2304kbps (N=1~36). For Annex F and G, the rate can be adjusted in increments of 64kbps from 64kbps to 5696kbps (N=1~89). Setup Serial Parameter, Clock Polarity The data port clock polarity may be adjusted to solve some rare clocking issues.
Page 65
The behavior of the RTS (Request To Send) signal may be set in one of two ways. When set 'on', the RTS signal is always forced high (on, positive voltage or SPACE), when set 'from DTE' the RTS signal will follow the DTE's condition. The default setting for RTS is on. Setup Serial Parameter, CTS The behavior of the CTS (Clear To Send) signal may be set in one of three ways.
Page 66
Setup Serial Parameter, DSR The behavior of the DSR (Data Set Ready) signal may be set in one of three ways. When set 'on', the DSR signal is always forced high (on, positive voltage or SPACE), when set 'off' the signal is always forced low (off, negative voltage or MARK), or DSR will follow DTR (Data Terminal Ready) condition of 'on' for DTR on or 'off' for DTR off.
Setup Serial Parameter, Delay The delay setting is used to cause a delay for CTS to follow RTS. The delay setting may be set from 0 to 3 milliseconds. The default setting is 3 milliseconds. 4.4.5. Configure Ethernet parameter When using on Ethernet interface mode, select the Ethernet item and press [ENTER] or [RIGHT]. The Ethernet settings include the data rate, negotiation, duplex the speed.
Page 68
Setup Interface Parameter, Data Rate For Annex A and B, the rate can be adjusted in increments of 64kbps from 64bps to 2304kbps (N=1~36). For Annex F and G, the rate can be adjusted in increments of 64kbps from 64bps to 5696kbps (N=1~89).
