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 (ESBC) 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.

Access the tdm-config configuration element.

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

In tdm-config, set the following:

state

Set to enable to allow TDM operations.

calling-pres

Set the type of call ID presentation for this profile. Valid values: allowed_not_screened, allowed_failed_screen, allowed_passed_screen, prohib_not_screened, prohib_passed_screen, prohib_failed_screen, prohib, unavailable.

Default: allowed_not_screened

caller-ID

Set the type of caller ID for CLIP and COLP for this profile.

Valid values: no, rpid (remote-party-ID), pai (p-asserted-ID)

Default: No

called-type- of-number

Set the type of Number and Numbering Plan associated with Called Party information. Valid values: unknown | local | national | international | dynamic.

calling-typre-of-number

Set the type of Number and Numbering Plan associated with Calling Party information. Valid values: unknown | local | national | international | dynamic.

In tdm-profile, set the following:

Name

Set the name for this TDM profile.

Signaling

Do one of the following:

Set pri_net when you want the ESBC to represent the network side of the connection.
Set pri_cpe when you want the ESBC to represent the Customer Premises Equipment side of the connection. Default.

Switch Type

Set a switch type for this configuration.

Valid values: national, dms100, 4ess, 5ess, euroisdn, ni1, qsig.

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 number of the spans affected by this profile.

Valid values: Single numbers 1-4. Any combination of 1,2,3,4 comma separated.

Route Group

Set the number of the associated route group to use this profile.

Valid values: 0-63.

Line Build Out

Set the decibel (db) level per foot of line length.

Valid values: 0-7. 0db up to 133 feet. Increment by 1db/133 feet after 133 feet. For example, 2db for 266-399 feet.

Framing Value

Set the framing value according to the line mode that you specified for this configuration.

For t1: esf
For e1: ccs

Coding Value

Set the coding value according to the line mode that you specified for this configuration.

For t1: b8zs
For e1: hdb3

CRC4 Checking

For e1, only. Enable or disable crc4-checking to match the setting of the PBX or service provider. Default: Disabled.

Time Source

Set the timing source.

Valid values: 0-4. Default: 1.

0—The interface provides its own timing.
1—The interface receives timing from the remote end.
2—The interface receives secondary timing from the remote end.
3—The interface receives tertiary backup timing from the remote end.
4—The interface receives quaternary backup timing from the remote end.

RX Gain

Set the decibel level that increases or decreases the TDM receiving channel volume.

Valid values: 0.0-9.9. Default: 0.0.

TX Gain

Set the decibel level that increases or decreases the TDM transmitting channel volume.

Valid values: 0.0-9.9. Default: 0.0.

Echo Cancellation

Enable or disable echo cancellation.

Overlap Dial

Set the overlap dialing function to either no or incoming, where incoming means yes.

Incoming Pattern

Set a list of extension numbers or match patterns. Separate single extension numbers with the vertical bar (|) character. A pattern starts with the underscore (_) character. In an extension pattern, note the meaning of the following characters:

X matches any digit from 0-9

Z matches any digit from 1-9

N matches any digit from 2-9

[1237-9] matches any digit in the brackets (in this example, 1,2,3,7,8,9).

. wildcard matches one or more characters

! wildcard matches zero or more characters immediately

Syntax examples:

Suppose the main number is 800-555-1234, one key extension is number 80, and the range of other extensions is from 8100-8399.

Match the exact number including the extension: 800555123480
Match the extension in a range: _80055512348[1-3]XX
Match the exact number including the extension or match an extension in a range: 800555123480|_80055512348[1-3]XX
