3 Primary Rate Interface Configuration

The Acme Packet 1100 and the Acme Packet 3900 support the ISDN Primary Rate Interface (PRI) for higher call-volume customers who want to connect PRI lines (t1,e1), analog trunk lines, analog phones (Extensions), Fax machines, and other analog communications devices to IP PBX/IP telephony systems. The PRI cards provide greater call-volume capacity than the Basic Rate Interface (BRI) card by providing more channels. In the U. S., the PRI card supports 23 b-channels for voice and user data at 64 Kbit per second and 1 d-channel for signaling. In Europe, the PRI card supports 30 b-channels for voice and user data at 64 Kbit per second and 1 d-channel for signaling.

When the system detects the PRI interface, it displays the corresponding configuration parameters in tdm-config and tdm-profile.

• With the single-port PRI, tdm-profile supports creating only one profile that applies to all spans.
• With the four-port PRI, tdm-profile supports applying a TDM profile to each span for more targeted routing. The tdm-profile sub-element supports enabling a particular span as the timing source, enabling echo cancellation for improved audio quality, and specifying a group of profiles for routing. When configuring multiple tdm-profiles, you can create a profile for each span individually or assign multiple spans to one profile. You can assign the profiles to a route group with either the same number or a different number per profile. For example you can configure a call to go to tdm:profileName, tdm:span:1 or tdm:group:2. You can send the call to a specific tdm interface or a group of them.

Span Configuration

TDM supports creating up to four profiles on the four-port PRI card. You can configure each span exclusively or set several spans (up to four) to share the same configuration. Each span represents a physical network interface. The span-number parameter in tdm-profile indicates the interface to which the profile applies. For example, span-number = 1,2,3,4 means that the profile applies to all spans. span-number = 1 means that the profile applies only to span 1. You can specify more than one span and fewer than four spans in the same profile, for example, span-number = 1,2. During configuration, the system validates that a particular span is assigned to only one profile.

On the single-port PRI card, you can set only one profile and it includes all spans.

Signaling Configuration

Depending on your deployment, you might need the Oracle® Enterprise Session Border Controller (E-SBC) to act as the customer premises equipment (CPE) side of the connection or to act as the network (NET) side of the connection.

For example:

• The E-SBC can act as the NET side of the deployment and connect to a PBX.
• The E-SBC can act as the CPE side of the deployment and connect to a network provider's ISDN line.

The system supports the coexistence of multiple profiles for both CPE and NET, and you can configure up to four profiles each. For PRI use pri_cpe and pri_net. For BRI use bri_cpe and bri_net.

Routing Configuration

For control over routing TDM traffic, each TDM profile includes the route-group number parameter that you can use to group profiles together for routing. You can route traffic by setting the following parameters for next-hop in the local-policy configuration:

next-hop = tdm:span:<number> Use span number to specify routing endpoints.

next-hop = tdm:group:<number> Each TDM profile includes route-group number, so that you can group profiles together. The route-group number can address several profiles for routing. During routing, the embedded Asterisk software that the E-SBC uses to connect PSTN and VoIP phone services to each other picks the first available span and the first available channel when routing to a group.

next-hop= tdm:<profileName> During configuration, the system checks to confirm that no other profile contains the same routing.

Configure the Single-Port Primary Rate Interface

The Acme Packet 1100 and the Acme Packet 3900 support the single-port ISDN Primary Rate Interface (PRI). To configure the PRI interface, you must set the parameters in tdm-config and tdm-profile under system. After you create the configuration, you must run either the Set TDM Configuration Wizard from the Web GUI or the setup tdm command from the ACLI to complete the configuration.

• Confirm the presence of the single-port PRI interface on the Acme Packet 1100.

Note that because the single-port interface supports only one profile, you can set either pri_cpe (Customer Premises Equipment) or pri_net (Network) for signaling. The setting you choose depends on the setting at the other end of the connection. Set this configuration to the opposite of the other end. For example, when the setting at the other end is pri_net, set pri_cpe in this configuration.

Note:

The system requires the four-port interface to support profiles for both pri_cpe and pri_net.

Configure the Four-Port Primary Rate Interface

The Acme Packet 1100 and the Acme Packet 3900 support the four-port ISDN Primary Rate Interface (PRI) for carrying multiple Digital Signal 0 (DS0) voice and data transmissions between the network and an endpoint. To configure the PRI interface, you must set the parameters in tdm-config and tdm-profile under system. After you create the configuration, you must run either the Set TDM Configuration wizard from the Web GUI or the setup tdm command from the ACLI to complete the configuration.

• Confirm the presence of the four-port PRI.
• Plan the number of TDM profiles that you want. (You can add or delete profiles later, if your needs change.)

When the Oracle® Enterprise Session Border Controller (E-SBC) detects the PRI interface, it displays the corresponding configuration parameters. In the PRI configuration, the line mode that you specify dictates certain corresponding settings. You can set either t1 or e1 for line-mode, but note that each one requires certain uniquely compatible settings. 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. The following procedure shows the specific t1 and e1 settings, where required.

1. Access the tdm-config configuration element.

   ORACLE# configure terminal

Backward Compatibility for Multiple TDM Profiles

Suppose you configured the Primary Rate Interface (PRI) in a previous release that did not support multiple Time Division Multiplexing (TDM) profiles. Later, you upgraded to a release that supports multiple TDM profiles, and rebooted. The system sets route-group to 0 and span-number to 1,2,3,4 (on a 4 span card). The result is that all spans remain configured as before, when a single tdm-profile was the only possible configuration. The system routes through the same TDM profile as before the upgrade. If you want to route to specific spans after the upgrade, you can create TDM profiles for specific spans or refer to the exact span number in the next-hop (tdm:span:<number>) parameter under local-policy.
