ent-scr-isup

Use this command to add an allowed ISUP or TUP screening reference to the Allowed ISUP entity set. One or more message types can be associated with the allowed ISUP screening reference. The ISUP message types listed in this entity set are accepted from another network.

Parameters

isupmt/tupmt (mandatory)

ISUP or TUP message type.

Range:: 0 - 255, *
*—the full range of values from 0–255

sr (mandatory)

Individual ISUP screening reference to which this rule will be added. If the specified sr does not exist, it will be created.

Range:: ayyy
1 alphabetic character followed by up to 3 alphanumeric characters

actname (optional)

Name of the gateway screening stop action set. Stop actions must be administered using this parameter in conjunction with the gateway screening stop action table (see chg-gws-actset and rtrv-gws-actset ).

Range:: ayyyyy
1 alphabetic character followed by up to 5 alphanumeric characters

nsfi (optional)

This parameter specifies the next screening category that is used in the gateway screening process.

Range:

stop: The gateway screening process ends and the message proceeds through normal routing.

nsr (optional)

Next screening reference. This parameter indicates which screening reference in the specified screening category (nsfi) is to be used in the screening process.

Range:: ayyy
1 alphabetic character followed by up to 3 alphanumeric characters

Example

ent-scr-isup:sr=iec:isupmt=1:nsfi=stop

ent-scr-isup:sr=ibig:isupmt=1&&128:nsfi=stop

ent-scr-isup:sr=iall:isupmt=*:nsfi=stop

ent-scr-isup:tupmt=20:sr=tu01:nsfi=stop

Dependencies

If the actname parameter is specified, the nsfi-stop parameter must be specified.

The value of the actname parameter must already be defined in the Gateway Screening Stop Action table with the chg-gws-actset command.

The specified isupmt parameter or tupmt parameter value must not already exist in the specified sr.

If the nsfi parameter is specified, the value must be stop.

The nsr parameter cannot be specified if the nsfi=stop parameter is specified.

The GWSOA parameter combination should be known and valid.

The Gateway Screening Rules table can contain a maximum of 360,600 rules.

Notes

A range of values can be specified for the isupmt or tupmt parameter by separating the values that define the range by two ampersands (&&); for example, isupmt=025&&100 specifies all ISUP message types from 25-100. The value to the left of the&&must be less than the value to the right of the && in the range.

An asterisk cannot not be specified for a parameter value in this command unless an asterisk was specified for the parameter value in the original ent-scr-isup command.

TUP does not apply to SEAS. ISUP Message Type is the default.

To use TUP message type screening, an SIO screening reference with si=04 (TUP) must exist in the SIO table. The TUP screening reference specifies the SIO screening reference as the next screening reference parameter (nsr) value.

To use ISUP message type screening, an SIO screening reference with si=05 (ISUP) must exist in the SIO table. The ISUP screening reference specifies the ISUP SIO screening reference as the next screening reference parameter (nsr) value.

To screen for TUP and ISUP message types using a combined ISUP/TUP screen set, the SIO screening reference with si=4 and the SIO screening reference with si=5 must be two different screening references. The TUP screening reference specifies the SIO screening reference as the next screening reference parameter (nsr) value, and the ISUP screening reference specifies the SIO ISUP screening reference as the next screening reference parameter (nsr) value.

Output

When a screen reference is specified that is not yet associated with a screen set, the following output appears:

ent-scr-isup:sr=iec:isupmt=1:nsfi=stop
