Make sure the ACTIVE MAP is set to the correct map (the map you want running) before exiting the DS0 MAPS menu. Left arrow back to the main menu. Appendix D. Configuring the Unit for DSX-1 Applications Initial Setup 1. Setting up the Interfaces From the main menu, select INTERFACES. 2 Highlight the CONFIG menu for the T1 interface and press . 3 Right arrow to select FORMAT and choose ESF or SF. This format must match the format used by the other units in the network. Set the LINE CODE to B8ZS or AMI. This line code must match the line code used by the other units in the network. Set the EQUALIZATION or line build out. The default setting of 0 DB is usually sufficient. Set the CSU LPBK option to ENABLE, DISABLE, or DISABLE ALL based on whether looping to this unit from another unit will be allowed. 2. Mapping the DS0s From the main menu, select DS0 MAPS. Verify that the ACTIVE MAP is set to either MAP 1 or MAP 2. This is the map that is actively running on the unit. The unit has the ability to store two maps. •To edit the current map, press on EDIT/VIEW MAP 1 to view the map. (If Map 1 is the Active Map) •To edit the standby map, press on EDIT/VIEW MAP 2 to view the map. (If Map 2 is the Active Map) The listed on the left side of the menu corresponds to DS0s on the network T1 interface. The PORT number identifies the DS0 on the DSX-1 interface. The and PORT do not need to match; DS0s can be cross-connected from the network T1 to any DS0 on the DSX-1 interface. Scroll down to the DS0 that will be mapped. (Any DS0 can be mapped to the DSX-1 interface.) Set the SERVICE for the DS0 that you are mapping to DSX-1. Set the PORT of the DS0 that you are mapping. The port number entered specifies the DS0 on the DSX-1 interface and can be set to any available DS0. When mapping voice circuits with dedicated signaling channels, be sure to map the signaling channel to the proper DS0 on the DSX-1 interface. For example, ISDN D channel signaling is normally carried on DS0 24. Unless the equipment connected to the Total Access 6XX DSX-1 interface has been specifically programmed, it will expect a D channel on DS0 24. Map DS0 24 to Port 24 to provide the D channel in the appropriate timeslot. Set RBS to OFF or ON depending on the application. When passing voice circuits with in-channel signaling through to the DSX-1 interface, signaling bits are preserved by setting RBS to ON. For clear channel service to the DSX-1 interface (for voice circuits with a dedicated signaling channel and all data) set RBS to OFF (which ignores the signaling bits). Map all the DS0s as desired, and exit this menu by pressing the left arrow button. Your changes will automatically save when exiting the map. Make sure the ACTIVE MAP is set to the correct map (the map you want running) before exiting the DS0 MAPS menu. Left arrow back to the main menu. 5.APPENDICES (T1 ATM APPLICATIONS) The following example is for configuring T1 units with ATM firmware. However, all units using ATM firmware (SDSL, ADSL, SHDSL) may be configured in the same manner. To configure ATM Voice applications with other network types, disregard the T1 Interface Setup Instructions and configure your network interface as needed. Appendix A. Voice Gateway Quick Start Procedure (Voice Turn Up) Figure 7. Application Diagram Initial Setup 1. Setting up the Interfaces From the main menu, select INTERFACES. 2 Highlight the CONFIG menu for the T1 interface and press . 3 Right arrow to select FORMAT and choose ESF or SF. This format must match the format used by the other units in the network. Set the LINE CODE to B8ZS or AMI. This line code must match the line code used by the other units in the network. Set the EQUALIZATION or line build out. The default setting of 0 DB is usually sufficient. Set the CSU LPBK option to ENABLE, DISABLE, or DISABLE ALL based on whether looping to this unit from another unit will be allowed. From the main menu, select INTERFACES. 2 Highlight the CONFIG menu for the FXS interface and press . 3 Right arrow to select MODE and choose LOOP START, GROUND START, TANDEM (E&M), TR08 SINGLE, TR08 UVG, or DPO. This mode should be set based on the network configuration and the operation of each FXS port. All FXS ports are independent and do not need to have the same mode. Set the TX (dB) or transmit direction level for each port. The default value is recommended. Set the RX (dB) or received direction level for each port. The default value is recommended. Set the SVC MODE to IN SERVICE to activate the port. Set the LINE Z (line impedance) of each port based on the size of the network. The default value is recommended. Set the MSG IND to DISABLE or ENABLE. When set to ENABLE, talk path is always open, even in on-hook conditions, in order for FXS message tones to pass through. Disabling this feature will allow higher on-hook voltage but will not allow on-hook messaging other than caller ID. Configure the on-hook battery voltage using ...
