DIAL PLAN (PKT ENDPT) > USER TERM > IFCE CONFIG > SUPPORT DBU HANDSHAKE
Write security: 3; Read security: 5

This option is only available when the packet endpoint selected in the PORT/PEP field has backup sublinks.

SUPPORT DBU HANDSHAKE enables/disables the generation and acceptance of ADTRAN frame relay

handshake upon connection. If the endpoint is configured to route incoming calls based on the handshake

information, this option is automatically enabled. If another call routing method is in effect, however, this

option can be enabled to support the use of handshake information at the far end of the link.

DIAL PLAN (PKT ENDPT) > USER TERM > IFCE CONFIG > SUPPORT DBU HANDSHAKE
Write security: 3; Read security: 5

Controls contents of the ADTRAN frame-relay handshake upon connection of a backup PVC. Normally

this field should be set to AUTO. The FORCED mode is present for compatibility with older IQ units.

DIAL PLAN (PKT ENDPT) > USER TERM > IFCE CONFIG > CALL PARTY NUMBER
Write security: 3; Read security: 5

(Visible only if GROUP is selected in the PORT/PEP field.) Enter the expected calling part number in this

field. The ATLAS 550 will use the number entered here to compare to the number presented by the

incoming call when configured to route based on Call Party Number.

DIAL PLAN (PKT ENDPT) > USER TERM > IFCE CONFIG > MIN DS0’S
Write security: 3; Read security: 5

Set this to 1 for typical single-call connections. A value greater than 1 will restrict connections to endpoints

supporting aggregation (e.g., BONDING) of the specified number of DS0s.

DIAL PLAN (PKT ENDPT) > USER TERM > IFCE CONFIG > MAX DS0’S
Write security: 3; Read security: 5

Set this to 1 for typical single-call connections. A value greater than 1 will accommodate connections to

endpoints supporting aggregation (e.g., BONDING) of up to the specified number of DS0s. This also sets

the number of DS0s presented in the negotiation of outgoing aggregate calls.

DIAL PLAN (PKT ENDPT) > USER TERM > IFCE CONFIG > CALL ROUTING TABLE
Write security: 3; Read security: 5

This table is only visible if GROUP is selected in the PRT/PEP field. The table format changes, based on the

DBU HANDSHAKE must be disabled for DBU between two ATLAS products.
