5 Local Policy Configuration for Time Division Multiplexing

Time Division Multiplexing (TDM) operations require policies for directing traffic to and from the TDM realm. After configuring the parameters for the TDM interface and running the Set TDM Configuration Wizard, 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, you specify tdmRealm for the source realm. In the outbound local policy, you specify the next-hop for TDM traffic.

Note:

When you upgrade from a previous release in which you configured an outbound TDM policy and you want to add an inbound TDM policy to the newer release, you need only to create the local inbound policy for TDM calls. The outbound TDM policy from the previous release persists.
