- 1.2 SS7 Architecture
1.1 Introduction
- The SS7 MTP Layer 2 Developer's Reference Manual specifies the interface from the host processor to the resident SS7 MTP layer 2 (link layer), independent of the host operating system and device driver employed.
- Subsequent sections of this document describe the general characteristics and operation of the MTP 2 APIs as well as a detailed specification of the messages and function calls that comprise the APIs.
1.2 SS7 Architecture
- A typical SS7/MTP 2 implementation consists of the following :
- The TX Alarms Manager task. This task collects unsolicited alarms (status
changes) generated by the MTP 2 task and forwards them to the host for
application-specific alarm processing.
- A TX driver for the host operating system which provides low level access
to the TX board from the host PC.
- The txalarm application on the host for displaying and optionally saving to
disk alarms from the MTP 2 task.
- The MTP 2 interface is comprised of a set of messages passed between the
user application (providing the SS7 MTP layer 3 functionality) and the
MTP 2 process on the TX communications processor. These messages
allow the (layer 3) application to initialize, transfer data, and exchange
status information with layer 2, enabling the (layer 3) application to
implement the link and traffic management procedures defined in the
relevant standards for layer 3.
- The mtp2cfg utility that downloads text file configurations to the MTP 2
task. mtp2cfg is provided in source and executable form.
- The mtp2mgr utility that allows a user to manage the MTP 2 task. mtp2mgr
is provided in source and executable form.
- The mtp2app and mtp2itu sample user applications also provided in source
and executable form. These sample applications take user commands and
send messages to the MTP 2 task.
- The MTP 2 Management API that provides a series of calls for managing
the MTP 2 task. The mtp2cfg and mtp2mgr both use this API.
