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, you need only to create the local inbound policy for TDM calls.

Configure the Inbound TDM Policy

Time Division Multiplexing (TDM) operations require policies for directing traffic to and from the TDM realm. In the following procedure, you specify the attributes for inbound TDM traffic.

• Configure TDM.

In the following procedure, the to-address and from-address can match the caller and called phone number or you can use any of the valid values noted. You must use tdmRealm for source-realm.

1. Access the local-policy configuration element.

   ORACLE# configure terminal
   ORACLE(configure)# session-router
   ORACLE(session-router)# local-policy
   ORACLE(local-policy)#

2. Set the following parameters.

   from-address	Set the origin address. Valid values: <ipv4> | <ipv6> | POTS Number | E.164 Number | hostname | wildcard
   to-address	Set the destination IP address. Valid values: <ipv4> | <ipv6> | POTS Number | E.164 Number | hostname | wildcard.
   source-realm	Set tdmRealm as the source realm.
   description	Enter a description of the policy.
   state	Set state to enable. Valid values: enable | disable.
   policy-priority	Set the priority of the policy. Valid values: none | normal | urgent | non-urgent | emergency.
   	policy-attributes Set the following policy attributes: next hop. Set the next hop. Valid values: Only for the PRI and BRI interfaces—next-hop tdm:span:<number> Only for the Analog interface—next-hop tdm:channel:<number> next-hop tdm:group:<number> next-hop tdm:<profileName> realm: Set the realm for the next hop. action: Set the action to take. Valid values: none | redirect | replace-uri. Default: none. cost: Set the cost. Range: 0-999999999. Default: 0.

• If your deployment requires an outbound TDM policy, see "Configure the Outbound TDM Policy."

Configure the Outbound TDM Policy

Time Division Multiplexing (TDM) operations require policies for directing traffic to and from the TDM realm. In the following procedure, you specify the attributes for outbound TDM traffic.

For the next-hop:tdm attribute, note that span and channel hops depend on the interface.

1. Access the local-policy configuration element.

   ORACLE# configure terminal
   ORACLE(configure)# session-router
   ORACLE(session-router)# local-policy
   ORACLE(local-policy)#

2. Set the following parameters.

   from-address	Set the origin address. Valid values: <ipv4> | <ipv6> | POTS Number | E.164 Number | hostname | wildcard
   to-address	Set the destination IP address. Valid values: <ipv4> | <ipv6> | POTS Number | E.164 Number | hostname | wildcard.
   source-realm	Set the source realm.
   description	Enter a description of the policy.
   state	Set state to enable. Valid values: enable | disable.
   policy-priority	Set the priority of the policy. Valid values: none | normal | urgent | non-urgent | emergency.
   policy-attributes	Set the following policy attributes: next hop. Set the next hop. Valid values: Only for the PRI and BRI interfaces—next-hop tdm:span:<number> Only for the Analog interface—next-hop tdm:channel:<number> next-hop tdm:group:<number> next-hop tdm:<profileName> realm: Set the realm for the next hop. action: Set the action to take. Valid values: none | redirect | replace-uri. Default: none. cost: Set the cost. Range: 0-999999999. Default: 0.
