SS7 Software

All CCS7 software to date has been written entirely in "C". Versions are available that run under the DOS (PC or MS DOS 6.2) environment for IBM Personal Computers (Microsoft Visual C/C++ compiler Version 1.5), and under the QNX Operating System (Whatcom C/C++ Version 9.52).

Control of all physical and network level parameters is provided through configuration files, keyboard commands or function calls allowing for complete control of items such as timers, error rate monitors, flag insertion, error checking mode (BEC or PCR) and others.

Our CCS7 software development library includes Message Transfer Part (MTP) for Signaling Point (both ANSI and CCITT), Signaling Connection Control Part (SCCP) both connectionless (ANSI and CCITT) and connection oriented (CCITT) services, Transaction Capabilities Application Part (TCAP) both CCITT and ANSI, as well as TC-User, application and management layers in the host. We have implemented two versions of Telephone User Part (TUP) on a contract basis for our customers.

Our implementation of Customer Routing Point (CRP) for Intelligent Call Processing (ICP) has been qualified by AT&T for connection to their network. This application uses two CCS7 Attachments connected to the AT&T Signaling Transfer Point (STP) via A links in a combined link set arrangement and includes software for ANSI MTP, ANSI SCCP connectionless service, CCITT TCAP and TC-User Application Service Element (ASE) to comply with AT&T TR54022.

Our implementation of LIDB access for billing validation is presently installed and tested and has passed long term acceptance testing at SBC (Southwestern Bell).

Several installations at other network providers (primarily for IS-41 cellular service support) are in operation or certification and testing stages.

Danar Corporation normally licenses software as part of a development project and provides the customer with full source code and a limited application license negotiated as part of the project contract. Due to recent developments we now have available an object module library package to support AT&T Intelligent Call Processing (ICP) Customer Routing Point (CRP), and an object module library package for Line Interface Database (LIDB) Access.

Arrangements for hardware design information and software source escrow accounts as well as long term maintenance agreements are available.


Switch Billing Transport System (SBTS)

Danar Corporation is in the process of completing it's first implementation of our Switch Billing Transport System (SBTS) for a PTT. This system will transport local measured service (LMS) billing data using FTP on top of TCP/IP from a number of different switch types to a common billing center.

This system uses pairs of IBM RS/6000 computers running AIX 4.2 coupled into a fault tolerant configuration to collect the AMAT data. Interfaces are already defined for EWSD, NEAX, and EWSA switches. Data reformatting to a common billing format is available as an option. This system uses both mag-tape emulators and serial interfaces to collect the billing information. No additional software from the switch manufacture is needed or required to implement this system.

The Switch Billing Transport System is highly centralized with all of the scheduling and administrative chores handled from one location further increasing security and efficiency in the billing collection process.

The system is written entirely in C under UNIX. X-window interfaces are provided for system management and status.
