SS7 Raw Data to Host

The SS7 Raw Data to Host feature allows the customer a way of tracking all Message Signaling Units (MSUs) and Link Status Signaling Units (LSSUs) transmitted to the network and received from the network.

This feature allows the SS7 Series 3 and SS7 PQ cards to send PPL event indications containing LSSUs and MSUs (received from the network as well as sent to the network) to the host. The PPL Configure (0x00D7) message is used to enable and disable (default) the feature.

This feature is initiated by setting (enabling) configuration bytes 0x10 in the following PPL components:

• Enabling the PPL event indications containing the raw LSSUs for transmission/reception to and from the network is done by enabling the configuration bytes 0x10 in the MTP2 LSC and MTP2 IAC PPL components.

• Enabling the PPL event indications containing the raw MSUs for transmission/reception to and from the network is done by enabling the configuration bytes 0x10 in MTP3 HMDT and HMRT PPL components.

When the feature is enabled all the supported LSSUs and MSUs are reported to the host in the PPL event indication.

In PPL, a condition that, when met, drives a state machine (PPL Component) from one state to another, by invoking an associated Primitive. In PPL files, an Event is marked by an arrow and text.

AF. A predefined PPL software routine that performs a single, simple task, such as "Transmit Line Signaling" or "Allocate Digit Buffer." It is composed of standard software interrupts, calls, and data formats used by applications. Each AF has two values named "Arguments." AFs 1-50 are generic, and apply to all PPL components. AFs 51 and above apply to specific components. An AF is called "Atomic" because it is the smallest useful unit in PPL.
