I. Problems

Most of small and medium enterprises are operating in those industries of comparatively sufficient market competitions, where there tend to be rapid changes and intense competition on the market. Therefore, such enterprises need to be bestowed with lower operation costs, flexible management measures and quick market response capabilities.   As far as most of small and medium enterprises are concerned, however, all of their cost controls, marketing means and response capabilities would be subject to the restriction of their communication systems.

Generally, corporate communications are divided into data communications and voice communications, where the applications of the former would mainly involve Email, IM and business systems (e.g. CRM, OA), etc, which are carried via the IP networks such as LAN, WAN and so forth; and the latter, which is usually established on the basis of traditional PSTN (public switched telephone network), would adopt the PBX (Private Branch Exchange) exchangers.


1. Voice communications based on the PSTN can produce relatively higher communication costs, and can be hardly controllable.

While a switching system based on PSTN applies the circuit-switching mode, communications in such a system can produce relatively higher costs as a result of sole occupation of communication channels by the system speech channels. According to statistics, voice communications can approximately account for 70% of total communication traffic, and communication costs thereof can in average, occupy about 40% of total operation costs of an enterprise. For those enterprises with a number of disperse branches and subsidiaries, costs arising from the communication can be even higher. Consequently, small and medium enterprises would have demands for voice communication of lower costs, and in particular, for the long distance voice communications.  


2. Unified management can be hardly realized over communication systems

While there can be higher stability of a switching system based on PSTN, the closeness of system structures would make it very hard for telephone users to carry out the reasonable control of communications at communication terminals effectively, so that there would be a lack of unified planned communication strategies, or difficulties to form such strategies in the number specification or control of phone call charges, or the loss of control of management to result in the increase of costs.      


Thus, small and medium enterprises would demand simple and effective means to achieve the highly efficient control of their communication systems.


3. Communication systems can provide weaker support to corporate business operations.

At present, informationized applications based on the data services such as Web, Email, CRM, OA and so on have become rather mature among small and medium enterprises. Benefiting from such advantageous features of IP technologies as simplicity, openness and flexibility, these applications have buttressed a vast majority of business operations in such enterprises. Yet in terms of business development, customer contact and technical services, what mostly utilized in such enterprises would be more often than not the voice communications. Due to the poor closeness and fusion of existent communication systems, their interconnection with the corporate business operation systems can be hardly realized, resulting in the low level of automation of business development.

To complement the deficiencies of traditional communication systems, small and medium enterprises would often need to increase their manpower and material resources substantially, but would be unlikely to achieve good results.

The Donjin unified (converged) hypermedia switch can accomplish voice switching within one same network or between different networks and can mainly involve such functions as media conversion, signal analysis and voice switching. Simultaneously equipped with both the IP phone server and VoIP media gateway functions, the Donjin unified (converged) hypermedia switch can realize the mutual voice communications between various branches and subsidiaries through the WAN, and can in the meantime, connect the IP networks and PSTN local telephone networks, while the WAN can support any form of data networks such as VPN, xDSL and so on. The switch can be accessed with both digital trunk and analog trunk units to support the SS7, SS1and ISDN signals, support the H.323 and SIP protocols, and support the voice applications based on Skype, while supporting the G.723.1,G.729 and G.711 voice coding protocols in media processing. As a result, such a switch can have the voice activity detection, echo suppression and anti-delay & anti-differ functions.

Meanwhile, The Donjin unified (converged) hypermedia switch contains both the service and media processing resources such as conference bridge, fax server, Voicemail, voice record server, IVR and voice switching modules, and media processing modules.  The conference resource can provide a maximum conference of 512 parties, where the conference parties can be either from the telephone network users, or from the Internet users. Thus, supports can be provided to telephone conferences, call centers and Web-based voice applications of enterprises; The fax resource can accomplish the format conversion of faxes, detection of fax signals, and automatic sending and receiving and saving of faxes in batches; The voice recording resource can realize the real-time recording of telephone calls, thus providing support to corporate monitoring of businesses. The media process resource can realize such functions as IP voice, voice recognition, TTS, background sound effects and sound (voice)modification,etc.  

The Donjin unified (converged)hypermedia switch is internally installed with the CTI server so that it can also support the third-party CTI with an external server, and such protocols as CSTA AND TAPI, where the users can count on their computers to take control of telephones or telephone systems and thus share voice resources in networks. 


IV. Introduction to Functions

1. Realizing zero charge expense for internal calls of an enterprise

As this unified (converged) hypermedia switch can rely on the Wide Area Network (WAN) to connect to branches and subsidiaries in various areas, phone calls between the headquarter and branche & subsidiaries, and between various branches and subsidiaries can be directly conducted via the WAN or Internet, thereby saving all the charge expense for internal calls of an enterprise, while this switch can support such protocols as H.323 and SIP, and suppor the SKYPE connections. For those branches and subsidiaries aleady equipped with the traditional PBX switches, this switch can connect the PBX to Donjin gateway and further to the headquarter via this gateway; For those branches and subsidiaries that do not use the PBX switches, internal voice communications can be transmitted via the Local Area Network (LAN) to directly access the internal LAN into the WAN without the need of alternative wiring, thereby realizing the interconnection with telephone networks over the WAN or Internet. Meanwhile, this unified (converged) hypermedia switch can provide the local PSTN connections to realize the communication applications with voice quality assurance and minimum application costs for enterprises. 


2. Management of Internal Telephone Calls
