to the modem through a cable, it must be connected using a AYSNC-TO-DB25 or AYSNC-TO-DB9 adapter. There are more types of synchronous serial ports that can be supported in routers, such as Cisco Systems that can support 5 different types of interfaces, namely eia/tia-232 interface, eia/tia-449 interface, v.35 interface, x.21 Serial cable assembly and EIA-530 interface, corresponding to the adapter. It is important to note that, generally speaking, the adapter line ends with a different shape (g

. Because ISDN provides digital channels directly between End-to-end, it has the characteristics of high speed, high quality, high reliability, fast call connection, and can transmit data, voice and image information. WAN Protocol: X. 25 Technology X. For more than 25 years, it has been used as the interface standard between the user network and the packet switching network. Is the interface between a data terminal unit and a data circuit terminal unit in which terminals operate in a grouped

, released in 1969, is the most widely used serial interface for embedded systems and is designed to connect DTE (data Terminal equipment) with DCE (data communication devices). The RS-232 standard interface has 25 interfaces (4 data lines, 11 control lines, 3 timing lines, 7 spare and undefined lines), only 9 are commonly used, they are rts/cts (request send/clear Send flow control), RXD/TXD (data transmit

digital signal into an analog signal, and the receiver uses the demodulator to convert the received analog signal into a digital signal, which is the modulation and demodulation of the signal.The device that implements the modulation and demodulation tasks is called a modem. When using the frequency band transmission, each side of the communication is connected to a modem, and the digital signal is sent to the analog signal (carrier) for transmission. Therefore, this transmission is also known

directly transmitted by a serial interface or terminal is related to the transmission rate and the electrical characteristics of the transmission line. When the transmission line uses a non-balanced shielded twisted pair with a 50pf capacitor every 0.3 m (about 1 feet), the transmission distance decreases as the transmission rate increases. When the bit rate exceeds 1000 BPS, the maximum transmission distance decreases rapidly. For example, when the bit rate exceeds 9600 bps, the maximum distan

QHow can I program the implementation in applications to send and receive short messages through a serial port connected to a GSM mobile phone? QWe plan to develop a GPS system based on GSM Short Message. How can we use SMS for data communication? AFirst, we need to understand the SMS specification developed by ESTI. The rules related to short message sending and receiving discussed mainly include GSM 03.38, GSM 03.40, and GSM 07.05. The first two focuses on the technical implementation of SMS

switch/hub The crossover line is used for connection: 1. Switch and switch; 2. Host and host; 3. Hub and hub; 4. Hub and switch; 5. direct connection between the host and the router In practice, it is generally understood as follows: 1. Cross-line connections are used between devices of the same type, and direct-line connections are used between devices of different types; 2. vrouters and PCs belong to DTE devices, and vswitches and hubs belong to

At commandAt refers to attention. The AT Instruction Set is from the terminal device (terminal equipment, Te) or data terminal device (data terminal equipment, DTE) to the terminal adapter (terminal adapter, Ta) or sent by data circuit terminal equipment (DCE. Send AT commands via TA and te to control the functions of Mobile Station (MS) and interact with GSM network services. You can use AT commands to con

synchronous serial port types supported in the vro. For example, the Cisco system can support five different types of interfaces: EIA/TIA-232 interface, EIA/TIA-449 interface, V.35 interface, X.21 serial cable integration and EIA-530 interface, the corresponding adapter icons are 12, 13, 14, 15, and 16, respectively. Note that, in general, the two ends of the adapter connection adopt different shapes (generally called the "public" end with a pin, while the end with a hole is usually called "mot
