Configure Time Division Multiplexing

To perform Time Division Multiplexing (TDM) operations, the Oracle® Enterprise Session Border Controller (E-SBC) requires a profile that specifies the TDM interface. After you create the profile, you must run either the Set TDM Wizard from the Web GUI or the setup tdm command from the ACLI to complete the configuration.

• Confirm that the ESBC contains the optional TDM card.
• If you want to enable TDM logging in this procedure, you must enable system logging before you begin.
• If the E-SBC contains the optional Quad-Span card, determine the number of spans that you plan to use.

Use the tdm-config element to configure the TDM profile. The line mode that you specify dictates certain corresponding settings, as noted. For example, when you specify the T1 line mode you must specify ESF for the Framing Value. Do not specify an E1 value for the T1 line mode or a T1 value for the E1 line mode.

1. Access the tdm-config configuration element.

   ORACLE# configure terminal
   ORACLE(configure)# system
   ORACLE(system)# tdm-config
   ORACLE(tdm-config)#

2. In the tdm-config object, do the following:

   Attributes	Instructions
   State	Enable or disable TDM.
   Logging	Enable or disable TDM logging.
   Name	Set the name for this TDM profile.
   Line mode	Set either T1 or E1.
   Signalling	Do one of the following: Set pri-net, if you want the TDM card to use the internal clock as the timing source. Set pri-cpe, if you want the TDM card to use an external clock as the timing source.
   Switch type	Set a switch type for this configuration.
   B channel	Set the B channel value according to the line mode that you specified for this configuration. For T1: 1-23 For E1: 1-15,17-31
   D Channel	Set the D channel value according to the line mode that you specified for this configuration. For T1: 24 For E1: 16
   Span number	Set the span number to 0, whether the quad span card is present or not.
   Line build out	Set a number from 1-13.
   Framing value	Set the framing value according to the line mode that you specified for this configuration. For T1: ESF For E1: CCF
   Coding value	Set the coding value according to the line mode that you specified for this configuration. For T1: b8zs For E1: hdb3
   Tone zone	Set the tone zone value according to the line mode that you specified for this configuration. For T1: US For E1: ES
   Rx gain	Set the TDM receive volume in decibels. Maximum: 9.9
   Tx gain	Set the TDM transmit volume in decibels. Maximum: 9.9
   Echo cancellation	Enable or disable.
   Calling pres	Enable or disable call IP presentation for a SIP device. When you enable "calling pres," you must also enable "caller ID."
   Caller ID	Enable or disable caller ID for CLIP and COLP. When you enable "caller ID," you must also enable "calling pres."
   Options	When the E-SBC contains the Quad-Span card, set the number of channels that you want to use. Type number-of-span=<0-4>.

3. Exit to Configure Terminal.
4. Run the setup TDM command.

• Configure the inbound and outbound TDM local policies.
