Time Division Multiplexing

Oracle® designed the Time Division Multiplexing (TDM) functionality for companies planning to migrate from TDM to SIP trunks by using a hybrid TDM-SIP infrastructure, rather than adopting VoIP-SIP as their sole means of voice communications. The TDM interface on the Oracle® Enterprise Session Border Controller (E-SBC) provides switchover for egress audio calls, when the primary SIP trunk becomes unavailable. You can use TDM with legacy PBXs and other TDM devices.

• Only the Acme Packet 1100 and the Acme Packet 3900 platforms support TDM, which requires the optional TDM card.
• TDM supports bidirectional calls as well as unidirectional calls.
• TDM operations require the configuration of tdm-config and tdm-profile, as well as local policies for inbound and outbound traffic.
• The software upgrade procedure supports the TDM configuration.
• Options for the Acme Packet 1100 and the Acme Packet 3900 platforms include Calling-Line Identification Presentation (CLIP) and Connected-Line Identification Presentation (COLP).
• Options for the Acme Packet 1100 platform include the four-port Primary Rate Interface (PRI), the Euro ISDN Basic Rate Interface (BRI), and the Foreign Exchange Office-Foreign Subscriber Office (FXO-FXS) card.

Interface Requirements

PRI—Digium1TE133F single-port or Digium 1TE435BF four-port card.

BRI—Digium 1B433LF four-port card

FXS—Digium 1A8B04F eight-port card, green module (ports 1-4)

FXO—Diguim 1A8B04F eight-port card, red module (ports 5-8)

Notes

When you deploy either the Acme Packet 1100 or the Acme Packet 3900 in a High Availability (HA) pair, the active system cannot replicate calls between SIP and TDM to the standby system.

The Acme Packet 1100 does not support HA for the PRI, BRI, and FXO-FXS interfaces.

Time Division Multiplexing Configuration

To perform Time Division Multiplexing (TDM) operations on the Oracle® Enterprise Session Border Controller (E-SBC), you must enable TDM, specify the parameters for the interface in use, run the TDM configuration wizard, and create local policies for routing TDM traffic.

TDM configuration requires the following process:

1. Configure the tdm-config element and its corresponding sub-elements. The tdm-config element, located under system, contains the parameters that are common to all TDM configurations. The sub-elements contain the particular parameters for the interface that the system detects in use on the E-SBC. The system displays the sub-elements, as follows:
   • When the E-SBC detects either the Primary Rate Interface (PRI) or the Basic Rate Interface (BRI) interface, tdm-config displays the tdm-profile sub-element with the parameters that correspond to the interface. See "Primary Rate Interface Support" and "Basic Rate Interface Support."
   • When the E-SBC detects the Analog interface, tdm-config displays both the fxo-profile and the fxs-profile sub-elements with the parameters that correspond to the interface. See "Foreign Exchange Office-Foreign Exchange Subscriber Support."
2. Run the TDM configuration wizard to complete the configuration. The wizard creates the realm, SIP interface, steering pools, and other necessary configuration elements including the network interface and the phy-interface for SIP call routing. With SRTP enabled (default), 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 (Set TDM Configuration) or the ACLI (setup tdm).

   The Oracle® Enterprise Session Border Controller (E-SBC) requires running the TDM configuration wizard only after the initial TDM configuration. The system does not require you to run the wizard after you make changes to the existing configuration.

   Note:

   When the Oracle Session Delivery Manager (SDM) manages the E-SBC, you configure TDM from the SDM and you do not need to run the TDM configuration wizard. See "Time Division Multiplexing (TDM) Settings on the Session Delivery Manager (SDM)" for the required settings.
3. Configure the local policy for routing traffic 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. See "Local Policy Configuration for Time Division Multiplexing."

You can configure TDM from the following locations:

• ACLI—Use the tdm-config, tdm-profile, fxo-profile, and fxs-profile elements located under system.
• 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, tdm-profile, fxo-profile, and fxs-profile elements located under system.
• Session Delivery Manager (SDM)—Launch the Web GUI from SDM and use the tdm-config, tdm-profile, fxo-profile, and fxs-profile elements located under system.

Configure TDM

To perform Time Division Multiplexing (TDM) operations, the Oracle® Enterprise Session Border Controller (E-SBC) requires a profile that specifies the TDM interface.

• Confirm that the E-SBC contains the optional TDM card.
• If you want to enable TDM logging in this procedure, you must enable system logging before you begin.

In the following procedure, the line mode that you specify dictates certain corresponding settings, as noted. For example, when you select 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. From the Web GUI in Basic Mode, click the Configuration tab.
   The system displays the TDM icon in the workspace.
2. Double-click the TDM icon.
   The system displays the TDM configuration dialog.

   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. Enter number-of-span=<0-4>.
