Configuring SSUTR2

Purpose

This section explains how to configure SSUTR2 on an SS7 card and includes information about the PPL components and API messages used with this feature.

Before you begin

The following API messages need be used in the configuration of SSUTR2:

• Assign Logical Span ID (0x10)

• CCS Redundancy Configure (0x5B)

• SS7 CIC Configure (0x6A)

• SS7 Signaling Link Configure (0x5E)

• SS7 Signaling Link Set Configure (0x5D)

• SS7 Signaling Route Configure (0x5F)

• SS7 Signaling Stack Configure (0x5C)

• Service State Configure (0x0A)

• T1/E1 Span Configure (0xA9/0xD8)

Incoming and Outgoing Circuits

SSUTR2 defines specialized incoming and outgoing circuits. Specialized outgoing circuits are available only for outgoing calls, incoming MIFs (Initial Address), continuity recheck request, and blocking request received on these circuits are considered irrational. Similarly specialized incoming circuits are available only for incoming calls, outgoing calls and host-initiated blocking is not allowed on these circuits. A config byte is used in L3PCIC and CPC to allow the host to configure incoming and outgoing specialized circuits.

Configuration

This procedure describes how to configure the SSUTR2 in the general CSP configuration.

1 Assign and configure spans. Use the Assign Logical Span ID and T1/E1 Span Configure messages.

2 Configure SS7 cards. Use the CCS Redundancy Configure.

3 Configure Signaling Stacks. Use the SS7 Signaling Stack Configure.

4 Configure Signaling Link Sets. Use the SS7 Signaling Link Set Configure.

5 Configure Signaling Links. Use the SS7 Signaling Link Configure.

6 Configure Signaling Route(s). Use the SS7 Signaling Route Configure.

7 Assign Voice Circuits (CICs). Use the SS7 CIC Configure.

8 Bring spans, CICs and signaling links in-service. Use the Service State Configure.

SSUTR2 PPL Components

For TUP SSUTR2 outgoing continuity, two components are used specifically:

• TCCO--This variant handles outgoing continuity during outgoing call setup.

• SSU CRO--This variant handles the outgoing recheck procedure.

In addition, the PPL Component SCFG is used to configure the SSUTR2 variant and initialize the SSUTR2 PPL components "RW" and "RO".

Range of channels provided by T1 or E1 transmission service. A physical span is a group of channels taking up a single physical wire. A logical span is a group of channels taking up less than a single logical wire, or carried over more than one physical wire.

Link that connects to the same node
The condition of a component at a given instant. The current "context" of a PPL object, such as Idle, Seizing, Answered. In PPL files, a State is represented by a circle.
Digital communications link - voice, data, and video at a 1.544 Mbps rate (24 64 Kbps channels)
A digital communications link - voice, data, and video at a 2.048 Mbps rate; 30B/2D or 31B/1D (ISDN); non-North American version of T1.
Telephone User Part
A programmable software component that uses PPL state machines that can be modified with the PPL Tool.
