SURPASS hiE 9200
The SURPASS hiE 9200 soft switch is the main switch in every PSTN/ISDN network of the next generation network solutions. It controls the media gateways and coordinates the network intelligence present in the different members of the next generation network product family. It supports parallel and mixed operation over a PSTN/ISDN network, an IP network or both.
SURPASS hiE 9200 provides call control, multi-protocol support, and carrier-grade availability, as well as full class-4 and class-5 functionality. It provides the overall intelligence to control the other elements in the next generation network network, such as the media gateways. SURPASS hiE 9200 also provides flexible subscriber/ user services in any network. Furthermore, interworking with the PSTN network is coordinated by SURPASS hiE 9200 over ISUP signaling, which can be transported over IP.
hiG 1100 Media Gateway
The media gateway (MG) hiG 1100 provides the interworking between the TDM and packet networks, such as IP networks. It is controlled by the media gateway controller (MGC) via H.248. The hiG 1100 is a compact, scalable, switching system. The number of simultaneous calls supported per hiG 1100 system is independent of the codec used. hiG 1100 has a fix number of TDM ports, 16 or 32 E1 lines (i.e. a fixed number of DS0s available).
The hiG 1100 software system addresses the requirements of a media gateway within a distributed media switch architecture in accordance with IETF and ITU-T standards. The media gateway controller (MGC) contains the control logic and SS7 terminations. The applications for the hiG 1100 are created/controlled on the soft switches.

The media gateway (MG) hiG 1200 provides the interworking between the TDM and packet networks, such as IP networks. It is controlled by the media gateway controller (MGC) via H.248. hiG 1200 is a compact, scalable, switching system and a key component of next-generation-network (NGN) solutions. The hiG 1200 software system meets the requirements of a media gateway within a distributed media switch architecture in accordance with IETF and ITU standards.
The media gateway controller (MGC) contains the control logic and SS7 terminations. The applications for hiG 1200 are created/controlled on the soft switches.
hiG 1600
hiG 1600 provides all subscriber and trunk interfaces traditionally offered by a class-5 switch. These interfaces include POTS and ISDN (over DLU for direct subscriber connection) and open access interfaces, such as V5.2, for connecting any vendor access equipment. Inter-exchange trunks to the PSTN are also supported.
The traffic from these interfaces is packetized and sent to the converged IP core network. All profitable subscriber features for residential and business customers are still available under the control of SURPASS hiE 9200. One or more access routers connect hiG 1600 to the IP network. Appropriate redundancy mechanisms provide protection against failure of an access router or LAN failures. In next gereation network solutions, SURPASS hiE 9200 controls hiG 1600 V2 over a proprietary Access Control Protocol (ACP) and hiG 1600 V3 over H.248 (with a reduced feature set). Associated signaling system no. 7 (SS7) links which terminate on a hiG 1600 V2 system are tunneled through the IP backbone with circuit emulation service (CES) based nailed-up connections between hiG 1600 and the controlling SURPASS hiE 9200 system.
hiR 200/220
hiR 200/220 is an IP resource server which provides tones, announcements, and user interactive dialogs to the next-generation network (NGN) using voice over IP (VoIP) technology.
The servers perform the following main functions:
- Management server
Allows administration and supervision of the resource voice servers (RVS). The management server provides a remote Web GUI which allows the operator to connect to the management server from any Web browser in order to manage the resource voice servers remotely. The management server also provides FTP access for retrieving files, such as log files and statistic files.
- Resource voice server (RVS)
Provides the media stream interface to the network and the call control interface to SURPASS hiE 9200. The RVS receives MGCP requests from SURPASS hiE 9200, downloads the requested dialog or announcement in the form of a VoiceXML script from the resource content server (RCS), and plays it to the respective subscriber/user.
- Resource content server (RCS)
Provides announcements and dialog resources. The content is stored in the form of VoiceXML scripts and corresponding digitally recorded voice files in a large database of audio fragments.
SURPASS hiS 700
Stand-alone Signaling Transfer Point (SA-STP)
SURPASS hiS 700 provides the full functionality necessary for a powerful, reliable and scalable stand-alone signaling transfer point. Besides STP message handling for SS7 with up to 1,500 links and up to 600,000 message signal units per second (MSU/s), a dynamic performance capacity of 100,000 global title translations per second (GTT/s) can be handled with the signaling relay point functionality.
With the integrated Number Portability (NP) Server SURPASS hiS 700 optimizes network resources by transferring the number portability function from the IN platform to the stand-alone STP. The implementation of the mobile application part (MAP) allows the SURPASS hiS 700 to work as a virtual home location register (VHLR), introducing more flexibility for the mobile network numbering plan.
Signaling Gateway (SG)
SURPASS hiS 700 provides for a smooth migration of services and features from the TDM network into the data network by performing SS7 signaling over IP.
With the SS7 over IP interface SURPASS hiS 700
- fits perfectly into the existing global SS7 overlay network structure and
- offers all the benefits of high performance SS7 signaling to the IP network.
SS7 over IP is implemented according to the IETF SIGTRAN working group with the stream control transmission protocol (SCTP) serving as the transport layer for SS7 user parts (e.g. ISUP) and applications (e.g. INAP).
