Circuit and circuit group parameters

The circuit set parameters specify the characteristics of each of the circuit sets to be managed by the TUP layer, including the circuit identification codes (CICs) and destination point code (DPC) at the other end of the circuits. One entry is made for each circuit set. Any set can be designated as a predefined group by adding a group number to this definition. A predefined group can more easily be reset, blocked, and unblocked with the TUP functions or by the network.

Parameter

Default

Valid values

Description

CIRCUIT

None

1 through 65535

Number of the first circuit in this set. Circuits in this set are numbered from this number to (this number + NUM_CIRCUITS - 1). This range must be unique for all circuits defined. This number is used by the application and the TUP layer to identify circuits, but has no meaning to the far exchange.

CIC

0

0 through 4095

Circuit identification code (CIC) of the first circuit in this set. Circuits in this set are assigned CICs from this number to (this number + NUM_CIRCUITS - 1). This number range must agree with the CICs assigned to this circuit set at the far exchange.

DPC

None

N/A

Destination point code to which this circuit set connects. Use dotted notation, such as 2.45.76, or a hexadecimal number, such as 0x101.

ALT_OPC

None

N/A

Originating point code for this set of circuits. If not present, the OPC is set to OPC from the NSAP. Use this carefully with the appropriate MTP configuration changes and specified as x.y.z (three bytes, decimal value, separated by periods) or as a hexadecimal number (for example, 0xnnnnn).

0 through 65535

Group ID number to assign to this group of circuits. 0 designates these circuits as not being a group.
