5. Configuration with Console Port This chapter will deal with the details of configuration and operation of this product via console port with terminal emulation program. The configuration of the SHDSL.bis NTU is performed via a menu-driven embedded software, using a standard ASCII terminal or a PC running a terminal emulation application connected to the rear panel CONSOLE port. Windows includes a terminal emulation program called HyperTerminal.
5.1 Login Procedure At the start up screen, you will see: Press the SPACE key until the login screen appears. When you see the login screen, you can logon to device. Username use “admin”. When the system prompts you for a password, type “admin” to enter is O.K.
5.2 Window structure After you type the password, it will display the main menu. Above captured screen shows the common structure for all windows used throughout the configuration console terminal. From top to bottom, the window is divided into four major sections. The very top line displays the product name as “SHDSL.BIS NTU”. Next a block of commands is listed where the ">>" symbol indicates the current cursor placeholder. The next block down is the "command" section.
5.3 Main Menu Summary The main menu is prompted as following: Menu Title Function Setup Use this menu to setup SHDSL type, SHDSL parameters and E1/V.35/Ethernet parameters or restore factory default setting. Status Use this menu to show SHDSL status, E1 /V.35/Ethernet status and statistics or clear the statistics Show Use this menu to show general information, all configurations and all configurations in command script.
5.4 Configuration This section provides information about the configuration of SHDSL .Bis NTU. Follow the procedures: In the main menu, select setup and press [ENTER] or [RIGHT] The screen will prompt as following: For setup the local side, select LocCH and press [ENTER] or [RIGHT]. Otherwise, setup the remote side by select RmtCH.
5.4.1.
If the SHDSL.bis NTU is a multi-interface model, it will display more types of interfaces that can be selected. Use the [TAB] key to choose the different interface types.
5.4.2. Configure SHDSL parameters This section shows how to setup the SHDSL parameters: SHDSL Mode, Annex type, Psd Mask, SNR margin. Select Shdsl, and press [ENTER] or [RIGHT]. Setup SHDSL Parameter, Mode Press [TAB] to select the operating type and press enter to finish setting. The SHDSL modes have three types: STU-R, STU-C-INTCLK and STU-C-EXTCLK INTCLK: The device will generate the appropriate clock speed defined by the speed setting of the interface.
To set the SHDSL Annex type, move the cursor to Annex and press [ENTER]. Select the annex type by using [TAB] key. Set Up SHDSL parameter, Annex The Annex has four types: A, B, F and G. To configure the SHDSL PSD, move the cursor to psd and press [ENTER]. Select the parameter via [TAB] key. Set up SHDSL parameter, PSD The PSD has two types: SYM and ASYM.
To set the SHDSL Margin, move the cursor to margin and press [ENTER]. Select the margin via [TAB] key and key in the Next margin. Setup SHDSL parameter, SNR Margin SNR margin is an index of line connection. You can see the actual SNR margin in STATUS SHDSL. The larger the SNR margin, the better the line connection. For example, if you set SNR margin in the field as 3, the SHDSL connection will drop down and reconnect when the SNR margin is lower than 3. The setting range is -10 to 21.
5.4.3. Configure E1 parameters When using E1 interface, select the E1 item and press [ENTER] or [RIGHT]. The E1 setting includes the Channel (frame mode), line code, AIS and build out settings.
Framing Framing is required to recover the channelized E1. In transparent operation, the framing is configured as Unframed. In this case the G.SHDSL framer must be set to Nx64 with N=32. For any framing such as FAS or CAS, the G.SHDSL framer must be set to E1, then the E1 framing here may be set accordingly.
ITU 991.2 (2004) (G.SHDSL .Bis) supports data rate up to 5696Kbps, but G.703 (E1 standard) only supports data rate of 2048kbps so the maximum data rate of SHDSL line, connected with E1 DCEs, depends on data rate of E1, 2048kbps. E1 DTE SHDSL E1 STU-R (E1) STU-C (E1) DTE Frame E1 Data rate # of TS If the connection is E1 vs V.35 or V.35 vs E1, the framer has to use N x 64k. In this case, the data rate depends on value of N.
Fractional E1, PCM30 and PCM30C Using the E1 framing of PCM30(FAS+CAS) or PCM30C(FAS+CAS+CRC4), the FAS will occupy Time Slot 0 and CAS Time Slot 16. There are only 30 Time Slot left for data. On the other hand, the maximum data rate is 1920kbps.
Setup E1 Parameter, Pass Through When SHDSL.bis using 2-pairs(4-wires), the time slot number can only use even number When setting the E1 channel on PCM31C, PCM31, PCM30C and PCM30, there is also an E1 Pass Through selection item. Table of Pass through function with user data rate vs.
For example, when channel framing is PCM30 or PCM30C (with time slot number is 30 and first time slot is 1) refer to the following graphic. When Pass Through is set Off, the DSL transfer data will not include the time slots of FAS and CAS. The information of FAS and CAS on remote is re-created. Warning: When the E1 is carrying signaling information for voice, do NOT set pass through Off. Pass through must be set to ON or signaling and other information will be lost. Setup E1 Parameter, Line Code The G.
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 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 SHDSL.Bis NTU can support both unbalanced E1 at 75 ohms (BNC) and balanced E1 at 120 ohms (RJ-48C). The settings for impedance are made here under the build out menu setting.
5.4.4. Configure Serial parameters When using the Serial interface, select the Serial item and press [ENTER] or [RIGHT]. The serial settings include the data rate, clocking and handshaking lines setup. Setup Serial Parameter, Interface There are two interfaces types : V.35 and X.21. (For RS530/449 please select the X.21 interface.) Setup Serial Parameter, Data Rate - Rate type There are two rate type modes: Nx64K model and T1 mode.
Setup Serial Parameter, Data Rate For 2-wires with Annex A and B, the rate can be adjusted in increments of 64kbps from 64kbps to 2304kbps (N=1~36). For 2-wires with Annex F and G, the rate can be adjusted in increments of 64kbps from 192kbps to 5696kbps (N=3~89). For 4-wires with Annex A and B, the rate can be adjusted in increments of 64kbps from 128kbps to 4608kbps (N=2~72 , even number only).
Setup Serial 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 on (active low), 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.
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 on (active low), when set 'off' the signal is always forced off 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 Serial Parameter, DCD The behavior of the DCD (Data Carrier Detect) signal may be set in one of three ways.
Setup Serial Parameter, Delay The delay setting is used to cause a delay for CTS to follow RTS. The delay setting may be set 0, 1, 2 or 3 milliseconds. The default setting is 3 milliseconds. It works only for the setting: CTS follow RTS and RTS follow from DTE . 5.4.5. Configure Ethernet parameter When using the Ethernet interface mode, select the Ethernet item and press [ENTER] or [RIGHT].
Setup Ethernet Parameter, Data Rate – Rate type There are two modes: Nx64K model and T1 mode. When the remote side has T1 interface and unframed mode connect to this side as Ethernet interface, we must set Ethernet rate mode as T1 mode. Setup Ethernet Parameter, Data Rate For 2-wires with Annex A and B, the rate can be adjusted in increments of 64kbps from 64kbps to 2304kbps (N=1~36). For 2-wires with Annex F and G, the rate can be adjusted in increments of 64kbps from 192kbps to 5696kbps (N=3~89).
Setup Interface Parameter, Negotiation The Ethernet settings include the choice between auto-negotiation (default) or forced mode for duplex and speed. Be very careful to set both Ethernet devices on a link to both auto or forced and do not mix or a duplex mismatch could result. Setup Ethernet Parameter, Duplex When auto negotiation setup is disable, there has to be a selection of duplex mode: Full-Duplex and Half-Duplex.
Setup Ethernet Parameter, Speed When auto negotiation is Disable, the forced mode settings for speed can be set between: 10M and 100M. If auto negotiation is Enable, the items Duplex and Speed cannot be set. The message will display “Ethernet is in auto negotiate”. 5.4.6. Configure T1 parameter When using the T1 interface mode, select the T1 item and press [ENTER] or [RIGHT]. The T1 settings include the Channel, Number of time slots , First time slots, LBO and AIS.
Setup T1 Parameter, Channel The Superframe(SF) (also called D4 or 193S) framing format defines a superframe as 12 frames. The Extended Superframe (ESF) (also called 193E) frame format groups 24 frames into its superframe. Both the SF and ESF framing formats provide an actual payload data rate of 1.536 Mbps (192/193 = 1.536/1.544). The T1 interface can be programmed to encode/decode its transmit/receive signals using Bipolar with Eight Zero Suppression (B8ZS) coding.
Setup T1 Parameter, Time Slot number and First time slot For fractional T1, the data rate is from 64k(N=1) to 1536k(N=24), according to the T1 framing. When SHDSL.bis is using 2-pairs(4-wires), the time slot number can only use even number Setup T1 Parameter, Channel use Unframed mode Unframed: All transmitted bits are used as data bits. This selection must be used when the clock rate of the remote unit is set at 1.544 Mbps. In this mode the T1 signal is passed transparently without regard to framing.
