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 with 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.

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
