Telesis X1 TDM - IP Telephony Switch

Carrier class system. The X1 TDM - IP Telephony Switch.

State-of-the-art Technology

The Telesis X1 TDM - IP Telephony Switch has an architecture for NGN (next generation networks) migration with its integrated packet and circuit switching technology. The capacity is sufficient or easily expandable to ensure the availability of capacity needed for future new functions or services to be introduced.

The Telesis X1 TDM - IP Telephony Switch is capable of inter-working between all its TDM and IP signaling/protocol schemes. Each variant of incoming and outgoing lines associated with a signaling system generates and receives forward and backward  inter-working telephony events according to on-line, real-time procedures specified for each signaling system in the relevant standards and recommendations.

Various local and remote users of the X1, which can be IP or TDM.

System Capacity and Applications

Telesis X1 TDM - IP Telephony Switch capacity depends on the demands and the place of the system in the network. Particular values are defined for each system. The X1 allows, in an economic way, the realization of IP and TDM switching system in the capacity range of thousands of subscriber lines, thousands of trunks, and thousands of IP users. In order to facilitate expansions of the system in future, the X1 TDM - IP Telephony Switch is built on a modular principle. It is possible to distinguish functional units that can be replaced and/or expanded.

The Telesis X1 TDM - IP Telephony Switch has a modular structure. The installation of the system or expanding an already operating one by adding subscriber and/or trunk line interfaces is simple and fast. The X1 TDM - IP Telephony Switch allows thousands of H.323 endpoints to be registered into its integrated gatekeeper. These endpoints may be IP trunk routes and/or H.323 hard/soft phones with their own IP addresses. The X1 can also register to multiple gatekeepers simultaneously. Similarly, the X1 allows thousands of SIP user agents to be registered into its integrated registrar. These user agents may be IP trunk routes and/or SIP hard/soft phones with their own IP addresses. The X1 can also register to multiple registrars simultaneously. In an X1, TDM circuits, H.323 endpoints, and SIP user agents exist altogether.

Furthermore, Telesis proprietary xSIP (eXtended SIP) protocol allows value added services to be functional over IP.

Another challenging feature available with Telesis X1 TDM - IP Telephony Switch is the Telesis WebPhone. It is a SIP softphone or client applet hosted in the X1. The applet can be run from any java enabled web browser. Since it is a standard java applet, no software installation is required or no plugin is installed. The applet is just loaded temporarily onto the client`s browser. It can be used wherever is an access to the Internet. A web browser, a microphone, and a headset are sufficient to make calls.

Telesis WebPhone Main Page for the Browser

Telesis WebPhone is completely an independent application. It works with all main browsers such as Internet Explorer, Mozilla Firefox, Opera, Google Chrome, or Safari. The feature empowers web sites of Telesis X1 owners. Deploying the webphone on a web site is just an issue of placing a simple html link to the hosting Telesis X1 system. 

 

 

Utilities for System Owners and Administrators

XTools is a next generation utility software developed by Telesis A.S. to be used with Telesis X1 TDM - IP Telephony Switch. Moreover, it is freeware.

Experts as well as novices may get the benefits of XTools. An easy to use and flexible toolkit allows system owners and administrators:

  • to discover Xymphony compatible Telesis equipment in the local network and edit their settings
  • to trace and capture telephony events and call control messages of selected TDM users
  • to download CMDR (Call message detail recording) records
  • to download automatic voice recordings 
  • to generate formatted CMDR reports 
  • to trace, select, view or backup CMDR database

to trace, select or play voice recordings

By means of expansions and adaptations it is possible to use the X1 as:

  • Carrier grade Large Capacity TDM and IP Telephony System
  • Hybrid TDM and IP Telephony System for large enterprises
  • SSP, Service Switching Point for SS7
  • STP, Signal Transfer Point for SS7
  • Central Office
  • Toll switch
  • Tandem switch
  • Transit switch
