SMSC client .NET for SMPP, UCP, CIMD/CIMD2 and SEMA is a 100% managed .NET (DotNET) and COM (ActiveX/OCX) component DLL library for high performance SMS/EMS/WAP send & receive message communication through SMSC over TCP/IP. The components deliver high performance and wide range of features in communication with SMSC still guarding simplicity which allows for very quick delivery of a working solution.

Library consists of four .NET managed 32/64 bit, invisible, toolbox-installable components each implementing separate protocol (SMPP, UCP, CIMD2 and SEMA). Components can be mixed and used in multiple instances when parallel access to multiple mobile networks is required. The functionality is unified between protocols, and as a consequence the process of creating even complicated applications is simple and clear. At the same time programming interface of our components accepts set of advanced optional parameters to access low level protocol features if there is a need to.

Features:

· Implementation of both simple synchronous and high performance asynchronous (sliding window) mode for both sending and receiving of the messages and status reports allows to build applications that require very high throughputs - Multithreading construction for maximum performance sending and receiving messages
· Receiving messages originated by mobile stations (MS) to large accounts (short 4-5 digit network numbers) - which is used for contests, surveys, voting services, database queries etc.
· Possibility to send and receive SMS, EMS and WAP PUSH messages, messages containing images, animations, logos, sounds etc.
· Ability to send and receive generic 7-bit text messages, Unicode (UCS2) and 8-bit binary data messages with ability to send and receive special and national character sets (e.g. Arabic, Hebrew, Cyrillic, Chinese, Korean etc.)
· Support for GSM alphabet encoding with escape sequences allows to send and receive special characters (e.g. EURO currency symbol)
· Receive information about the message delivery status - Support for messages containing User Data Header (UDH) dependant functionality
· Possibility to send messages in Direct Display mode (a.k.a. flash SMS) - Possibility to set message delivery and validity time
· Possibility to attach an alphanumeric signatures to messages
· Connection keep-alive functionality
