BRI vs. PRI (T1) Ports

There is a subtle but very important difference in the UI between ISDN/BRI Signaling Groups and ISDN/PRI Signaling Groups. These differences appear in the Port and Protocol panels.

Specifies the TEI to assign for BRI when set to user side. 0 through 63 are absolute values to assign. If signaling group is PRI or network side BRI this parameter is not used. This field is available only when the TEI Assignment Type is set to Static.

Note
  The value of 0 for Static TEI is valid only for NTT. Other BRI specifications allow a value of 0 through 63 for Static TEI.

Specifies whether or not the Q.931 SETUP message is sent to the far-end should include the DISPLAY Information Element (IE).
Available only when ISDN Side is set to User and the Switch Variant is set to NI2 or Euro-ISDN.

If this option is enabled, the DISPLAY IE is populated for NI2 or Euro-ISDN switch types, otherwise the DISPLAY IE is not populated for these switch types.

In general, the DISPLAY IE is populated according to ISDN communication standards. The NI2 and Euro-ISDN specifications state that the DISPLAY IE should not be populated. This option allows you to override that configuration for your environment.
