TDM Configuration
The Time Division Multiplexing (TDM) option requires configuration. You must enable TDM on the Oracle® Enterprise Session Border Controller (E-SBC), specify the parameters for the TDM interface properties, and run the Set TDM Configuration Wizard.
- ACLI. Use the tdm-config object from the system group of elements.
- Web GUI - Basic mode. Double-click the TDM icon in the network diagram to display the TDM configuration dialog.
- Web GUI - Expert mode. Use the tdm-config object from the system group of objects.
You can configure TDM to support either the T1 line mode or the E1 line mode.
You can configure all TDM properties, except for line mode, in realtime. For example, changing the default T1 line mode to the E1 line mode requires a system reboot.
After you perform the initial TDM configuration, you must run the Set TDM Configuration wizard. The wizard completes the configuration by creating the realm, SIP interface, steering pools, and other necessary configuration elements including the network interface and the physical interface for SIP call routing. If you have an SRTP license, the wizard also creates the media-sec-policy object, enables the secured-network attribute for the sip-interface object, and configures the media-sec-policy attribute for realm-config. You can run the wizard from either the Web GUI or the ACLI. For more information, see "Set TDM Configuration Wizard."
After configuring the parameters for the TDM interface properties, you must configure the local policy for traffic routing through the TDM interface. For unidirectional TDM call routing, the system requires a local policy only for the call direction that you want. For example, inbound-only or outbound-only. For bi-directional TDM call routing, create both inbound and outbound local policies. In the inbound local policy, specify tdmRealm for the source realm. In the outbound local policy, specify the next hop that you want for TDM traffic.
If you upgrade from a previous release in which you configured outbound TDM and you want to add inbound TDM, you need only to create the local TDM policy for inbound TDM calls.
