Question: | What is SMSC? |
Answer: | A SMSC (Short Message Service Centre) is a 'service' provided by the network carrier, which enables you to send short messages (SMS), logos or ringtones to a mobile phone using your PC and a analouge modem or ISDN-card. Doing this a special protocol is used (TAP / UCP). |
  | |
Question: | What's TAP? |
Answer: | TAP (Telocator Alphanumeric Protocol) is a transmission protocol used for transmission of text-only messages (e.g. to a SMSC). |
  | |
Question: | What's UCP. |
Answer: | UCP (Universal Computer Protocol) is a transmission protocol used for transmission of text-messages, picture-messages, logos or ringtones. Not all SMSCs do support this protocol. |
  | |
Question: | After a logo or SMS was sent no confirmation from SMSC is received, neither a posotive nor a negative one. Simply the timeout runs. |
Answer: | The SMSC probably doesn't support UCP protocol, but only TAP. SMSMan only uses UCP, even for text-only messages. |
  | |
Question: | Once a logo was sent the modem simply disconnects. What's wrong? |
Answer: | Once again, probably the SMSC doesn't support UCP. |
  | |
Question: | Using a foreign SMSC for sending logos I get conformation the logo was received, the logo however never arrives. |
Answer: | You may have missed to ad the country code in front of the recipients call number. Use +4017... instead of 017...! |
  | |
Question: | Does SMSMan support ISDN? |
Answer: | No. The current version only supports analogoue modems. ISDN support is planned for a succeeding version. Stay tuned. |
  | |
Question: | How much is it to send a logo using SMSMan? |
Answer: | It's the cost of an phone call to the destination number. If you call a national SMSC it cost a national call; if you call an SMSC in another country (e.g. Swisscom from Germany) it costs you an international call. |
