The FAS word is located in timeslot 0 of frame. In FAS mode there have 1~31 timeslot available for use data.
Also known as time slot 16 multiframing. It requires a multiframe alignment signal to be present for frame sync. The Multiframe Alignment Signal (MFAS) is inserted into the 16th timeslot of frame 0 of the 16-frame multiframe. In CAS mode, there have 30 channels available for user data. If timeslot 16 is included in the unit’s mapping, it will be disregarded. CAS PCM30 and PCM30C / FAS+CAS and FAS+CAS+CRC4 The CRC-4 checksum bits are transmitted in the outgoing E1 data stream.
Fractional E1 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 PCM31(FAS) or PCM31C(FAS+CRC4), there are 1~31 available time slots for data use. For example, if the data rate of SHDSL line is set to 512k, the time slot number is 8 and first time slot number is 1. The frame is shown as below.
Setup E1 Parameter, Line Code The G.SHDSL NTU supports two different line codes: HDB3 or AMI. HDB3 is the most popular and preferred line coding and is also the default setting. AMI line coding is also selectable. HDB3 AMI In this line coding, the transmitter substitutes a deliberate bipolar violation when excessive zeros in the data stream are detected. The receiver recognizes these special violations and decodes them as zeros. This method enables the network to minimum pulse density requirements.
Setup E1 Parameter, AIS AIS (Alarm Indication Signal) is a method to inform the remote connection that there is a signal or sync problem with the E1. AIS is only valid in framed mode E1, not in Unframed E1. The setting here of AIS enabled (on) or not (off) and is for testing with AIS. When enabled, the E1 will transmit the forced AIS and it should be confirmed at the remote device (AIS indication lit). After testing, please turn AIS back off.
Setup E1 Parameter, Build Out The G.SHDSL NTU can support both unbalanced E1 at 75 ohms and balanced E1 at 120 ohms. The settings for impedance are made here under the build out menu setting. 4.5.4 Configure Data parameters When using the Data interface model, select the Serial item and press [ENTER] or [RIGHT].
The Serial settings include: Interface, data rate, clocking and handshaking lines (RTS, CTS, DSR and DCD) setup etc. Setup Data Parameter, Interface You can set Data interface to V.35 or RS-530(X.21,RS-449) hardware standard.
Setup Data Parameter, Data Rate For Data data rate, the default setting is N=32. The date rate can be adjusted in increments of 64kbps from 64kbps to 2304kbps (N=1~36). Setup Data Parameter, Clock Polarity The data port clock polarity may be adjusted to solve some rare clocking issues that can result from varying cable lengths.
Setup Data Parameter, RTS 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 Data Parameter, CTS The behavior of the CTS (Clear To Send) signal may be set in one of three ways.
Setup Data 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. The default setting for DSR is ON.
Setup Data 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. 4.5.5 Configure Ethernet parameters When using the Ethernet interface model, select the Ethernet item and press [ENTER] or [RIGHT].
The Ethernet settings include: data rate, auto config, duplex and speed. Setup Interface Parameter, Data Rate For date rate, the default setting is 36, or full rate. The date rate can be adjusted in increments of 64kbps from 64kbps to 2304kbps (N=1~36).
Setup Ethernet Parameter, Auto Configuration You can select Enable and Disable for auto configuration. When auto configuration enabled, the other parameters Duplex and Speed cannot be set.
If auto configuration is disabled, the other parameter Duplex and Speed can setup in forced mode. Setup Ethernet Parameter, Duplex You can set up the duplex mode as Full-Duplex or Half-Duplex.
Setup Ethernet Parameter, Speed You can set up the Ethernet speed as 10Mbps or 100Mbps. Duplex Mismatch issues When using forced mode Ethernet, be sure that both devices on the Ethernet cable are set to the same forced mode speed and duplex. Do not connect a forced mode Ethernet device to an auto negotiation device unless you set the forced mode device to half duplex. This is because when an auto negotiation device fails negotiation, it assumes a half duplex mode.
