Configuration of optional T1/FT1 CSU/DSU on S508 ================================================ .1 General The Sangoma S508/FT-1 is Sangoma S508 adapter with an integrated CSU/DSU unit. The S508/FT-1 is used to connect data terminal equipment to the T1 (1.544 Mbps) or Fractional T1 digital telephone network. This unit performs all Bell compatible encoding, decoding, timing and diagnostic responses. Set-up is done only infrequently. Monitoring and testing may be done from any network attached PC. .2 Configuration The configuration utilities can be found in the /DSU-FT1 directory on the Utilities Disk. Set- up can only be done under MS-DOS! It can also be done in a DOS window of Windows 95, and under DOSEMU of Linux, but not from the command prompt of Windows NT. Setup is performed by running the MS-DOS program GO.BAT. This batch file runs CFG_FT1.EXE which tests the card, loads it and then allows the user to pass configuration commands to the adapter. The Sangoma S508/FT-1 DSU has three memory banks: 1. The factory default. 2. The user configured bank. 3. The scratch pad (working memory). To check the current settings (bank settings), type D0 . Configuration changes are made as follows: 1. Type C to open the configuration mode. 2. Change the required settings. 3. After making these changes, type D1 to see the temporary configuration bank. 4. If these changes are correct, then type W to write the configuration to the non-volatile memory. 5. Type Q to exit the configuration mode. .3 Commands +n Add channel n (where n is 1-24) to the active list -n Delete channel n (where n is 1-24) from the active list M0 Set framing mode to ESF (Extendedsuper Frame) M1 Set framing mode to D4 K0 Set encoding mode to B8ZS K1 Set encoding mode to AMI L0 Set line build out to CSU (0db) or DSX-1 (0-133ft) L1 Set line build out to DSX-1 (133 - 266ft) L2 Set line build out to DSX-1 (266 - 399ft) L3 Set line build out to DSX-1 (399 - 533ft) L4 Set line build out to DSX-1 (533 - 655ft) L5 Set line build out to CSU (-7.5 db) L6 Set line build out to CSU (-15 db) L7 Set line build out to CSU (-22.5 db) P0 Set clock mode to normal (SLAVE) P1 Set clock mode to master (LDM mode only) W Write configuration to non-volatile memory F Get factory default configuration Q Exit configuration mode and move temporary (scratch pad) configuration to default configuration D0 Display actual configuration D1 Display configuration in temporary memory E0 Unit does not echo commands sent to it E1 Unit echos back commands sent to it T0 User test modes enabled T1 User test modes disabled NB: Whenever you have finished your changes, you MUST do a WQ in order for them to "take". After that do a D0 to check that the changes have, indeed been written to permanent memory. Example: Required configuration: Channels 1-3 disabled, channels 22 and 23 enabled Line build set to DSX-1 (399 - 533ft) ESF framing mode Clock mode to normal (slave) Type: C-1-2-3+21+22K0L3M0P0D1WQ OR C Open configuration mode -1-2-3 Remove channels 1, 2 and 3 from the active list +21+22 Add channels 21 and 22 to the active list K0 Set the encoding mode to B8ZS L3 Set the line build out to DSX-1 (399 - 533ft) M0 Set the framing to ESF P0 Set the clock mode to normal D1 Display the temporary configuration before saving W Update the user memory Q Close the configuration mode If you are adding or removing many D0 channels, break up the command into 2 or more commands, as the command line buffer has limited length. For instance, to drop the line speed to 128kbps, you need to remove channels 3 to 24. Do: C -3-4-5-6-7-8-9-10-11 -12-13-14-15-16-17-18-19-20-21-22-23-24 WQ D0 and the correct configuration should be shown. .4 Pinouts: RJ-48-s Telco Connector 4 TTIP Transmit 5 TRING Transmit 1 RTIP Receive 2 RRING Receive For back-to-back connections, cross connect: Side 1 Side 2 Red Grey Green Orange Grey Red Orange Green
