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.

Software Overview
Telesis X1 TDM - IP Telephony Switch`s leading-edge operational software, Xymphony, has been developed by Telesis specifically for this system. Among the many aspects of Xymphony is its advanced algorithm for creating routing tables, complete with options for Least-Cost Routing (LCR), real-time charging tables, and various subscriber/trunk classes. With many programmable features, Xymphony makes the traffic management highly efficient and versatile. The convenience of dealing with all-in-one standard software allows the user to support as many features as desired, up to the maximum capacity: thus, an organization`s capacity can grow without necessarily updating the software. Xymphony provides easy expansion and modification when introducing new services and technologies, to guarantee high reliability.

Traffic Handling Capacity
The Telesis X1 TDM - IP Telephony Switch has been tested with over 300,000 Busy Hour Call Attempts (BHCA) without any loss in the quality of service. The X1 employs a high-capacity switching matrix. The advanced design incorporates state-of-the-art Industrial CPU and Digital Signal Processors that are capable of executing hundreds of millions of instructions a second. Such highly efficient use of the system`s resources, with the help of intelligent algorithms, leaves very little, if any, possibility that an overload condition will arise.
The Telesis X1 TDM - IP Telephony Switch allows 8,192 H.323 endpoints or SIP user agents to be registered Furthermore, the Telesis X1 TDM - IP Telephony Switch allows up to 2,160 IP to TDM (or TDM to IP) calls at the same time (i.e., concurrent calls). In the operation of the X1 TDM - IP Telephony Switch, there is a sufficient margin for overload situations.
Traffic measurements of the X1 TDM - IP Telephony Switch provide the data base from which the dimensioning, planning, operation and management of the telephony network are carried out. Information gathered from these measurements can be used for identifying the traffic patterns and distribution on a route and destination bases, determining the amount of traffic in the switching system and the network, monitoring the continuity and grade of service.
System Management
The Telesis X1 TDM - IP Telephony Switch is managed over IP. Consequently, system programming and updating the Xymphony operating system can easily be managed either on site or remotely, through a WEB browser connection to web server integrated into the system. All system-management operations are performed without interrupting the functions of the system. The integrated web server allows:
- TDM user administration
- H.323 entity administration
- SIP entity administration
- Routing administration
- Call-charging administration
Furthermore, the Telesis XPort utility allows:
- Detailed monitoring of signaling
- Traffic measurement including collecting detailed call-data records
- Access to conversation records
- Access to alarm and system records
Operator`s System
Telesis X1 TDM - IP Telephony Switch operator`s systems are for both maintenance and call serving purposes.
Maintenance Purposes
Maintenance personnel can interface with the X1 TDM - IP Telephony Switch by means of the maintenance module to determine the system`s overall status, to program the system, to collect records, etc. The high reliability of the MMI`s ensures that any errors in commands and control actions do not cause the system to stop. Moreover, while commands are being entered or outputs provided from the system, call processing continues. Required Software in the PC is a WEB browser and Telesis XPort Software Utility.
In a Telesis X1 TDM - IP Telephony Switch, it is possible to define numerous maintenance users (maintenance personnel or maintenance operators) with their unique passwords. Each user should have a necessary authority while using an MML command in the system. For each group of MML command, a different authority level may be defined. So that, the available authority levels are a huge number of combinations. Furthermore, activation of MML commands are recorded in a log file with the relevant user names and time information.
Call Serving Purposes
The call serving operator`s system uses Telesis proprietary Xymphony-API server. Xymphony-API server in the Telesis X1 TDM - IP Telephony Switch, performs various telephony tasks such as dialing, call transfer, call park, call retrieve, conference, conversation recording, and display of port status. The physical connection is between a user`s personal computer, the same user`s analog/digital telephone line and the Telesis X1. Both the Xymphony-API server and the PC with Xymphony-API client utility (software) are in the same local area network. There can be multiple users or client PCs served by the same Xymphony-API server. XCom (Xymphony Companion), which is a Xymphony-API client software developed by Telesis, is an advanced screen-based telephone dialer and console with numerous features to integrate computer and Telesis X1 TDM - IP Telephony Switch for telephony needs.
