CLI, also known as Caller ID and calling number delivery ( CND ), is a service offered by the telephone service provider to customers to obtain the calling party number and date/time of the call. The service activation and information format of CLI are different from telephone network operator to operator. CLI display unit - minimum test setup In this project, we will create a small Caller ID decoder using Arduino UNO and a custom-made HT9032D module. The core component of the project is the HT9032D, which can decode incoming call ID data over a telephone connection. This IC supports Bell 202 FSK and ITU-T version 2.3 CLI protocol specifications. The HT9032D module we created here base on the application example given in the IC datasheet . In addition to decoding CLI data, this module also can detect ring signal rises over the phone line. Assembled HT9032D module The Arduino UNO is used to process the decoded CLI data stream and manipulate the LCD. In an idle state, the decoder a...

When purchasing SLT ( Sri Lanka Telecom ) PeoTV connection, we are getting a  preconfigured ADSL router and STB. Generally, the router they provided is a 4-port, low-cost ADSL router. The unit which I received with my PeoTV connection is " PROLiNK H5004NK ", and it is a decent quality 4-port ADSL router with a WiFi transceiver. I used this router for one year, and the main issues I noticed with this router are its unnecessary resets during heavy network traffic and limit configuration options. Due to the recent upgrade of my network, I replaced this router with the TP-Link W8961ND router. TP-Link W8961ND bundles with ADSL 2/2+ Modem, 300Mbps WiFi access point, and 4-port router. TP-Link W8961ND Router I purchased this router from a computer component seller and NOT from SLT. As usual, this router arrives with the default configuration, and I managed to configure it for SLT ADSL and PeoTV without any problems. The firmware version of this router is version 3.0...
