Numbering Plan:

Unknown

ISDN

National

Private

The setting Unknown is used when the user or network has no knowledge of the numbering plan. In this case, the number digits field is organized according to the network dialing plan.

B Channel Maintenance Message:

This setting controls B channel initialization and maintenance message exchange between AltiWare and the CO, when the system starts up. Select the maintenance message that will delivered on the B Channel:

None—no maintenance message sent; puts channel in ready state automatically.

Restart—only sends RESTART message; puts channel in ready state when RESTART ACK (acknowledgement) response is received from CO.

Service—only sends SERVICE message; puts channel in ready state when SERVICE ACK (acknowledgement) response is received from CO.

Restart and Service—(default setting) sends both RESTART and SERVICE message; puts channel in ready state when RESTART ACK and SERVICE ACK is received from CO.

Enable PRI Caller Name—check this box to enable PRI caller name

Setting the NSF

The NSF (Network-Specific Facilities) is used with PRI to instruct the CO to route a call to a specific carrier or long distance service. Use the drop-down list to identify the type of carrier service you want to use for your ISDN PRI lines.

The choices in the list depend on the specific switch and your long distance service provider. An example of such service includes AT&T Megacom.

Note: If your CO requires specific NSF features to be present in the call setup packet, please contact AltiGen’s Technical Support department with such information from the CO and they will help you configure it.

Setting a TEI

The TEI (Terminal Endpoint Identifier) defines which terminal device is communicating with the CO switch for a given message. PRI messages involve point-to- point configuration in which each side already knows the source of any message received. ISDN messages involve point to multi-point locations in which the source can only be identified by the TEI.

Select one of the following TEI settings:

Default setting—this is the recommended setting.

Manually set to—should always be set to 0. Typically, a zero (0) is used for TEI on a PRI connection. In some cases where a shared D channel is used, other TEI values might be required to identify which span will be used for a call.

Assigned by CO switch—do not use this setting unless advised by your CO.
