GL supports Interconnect User Part (IUP) Protocol

September 15, 2014. GL Communications Inc. announced today its latest product—MAPS IUP Protocol Simulator—which supports simulation of the UK-specific SS7 Interconnect User Part (IUP) Protocol over British Telecom (BT) TDM networks.

Karthik Ramalingam, senior manager for product development of the company, said the SS7 (C7) IUP is the UK national standard protocol used to interconnect two Public Network Operators. The IUP feature was derived from standards set by the Public Network Operators—Interconnect Signaling Committee (PNO-ISC).

He continued, “The IUP comprises a number of call setup, release, and supervision protocols, which provide additional call-control procedures. The call-setup protocols are used for bearer and call establishment. The call-release protocol is used for bearer release. The supervision protocols are used to exchange call status information between networks.”

Ramalingam further added, “The MAPS IUP supports powerful tools like Message Editor, Script Editor, and Profile Editor, which allow new scenarios to be created or existing scenarios to be modified…. It gives the flexibility of modifying any message so that we can easily duplicate the messages generated by any node to resolve interoperability issues.”

Main features include IUP simulation over TDM (T1/E1), support for multiple T1/E1 line interfaces, a user-friendly GUI for configuring the SS7 MTP layers, user-configurable signaling links, support for MTP2 and MTP3 protocol machines, and support for multiple MTP links. Support for client-server functionality through a Command Line Interface (CLI) via Python and TCL requires an additional license.
