The service of ISDN covers all services of the existing communication network, such as fax, telephone, visual text, monitoring, email, visual phone, conference and television, and can meet the needs of different users. Another basic feature of ISDN is to provide users with standard inbound interfaces. You can combi

different users. Another basic feature of the ISDN network terminal is to provide users with standard inbound interfaces. You can combine terminals of different business types, connect to the same interface, and change the terminal type at any time. There are two main types of ISDN network terminals: basic rate BRI) and basic group rate PRI ). All interfaces pro

1. Integrated digital service network ISDN)Integrated digital service network (ISDN) is composed of two parts: digital telephone and data transmission services, which are generally provided by the telephone Bureau. The Basic Rate Interface BRI of ISDN) Service provides two B channels and one D channel 2B + D ). The B-channel speed of BRI is 64 Kbps, which is used

) and base Group rate ISDN (PRI). For families and small and medium-sized users, BRI is the most suitable and most commonly used, the PRI provides faster data transmission capabilities, so it is suitable for large users.Basic Rate ISDN (BRI)A BRI consists of two channels, two B Channel to transmit data, each channel tr

, it does not affect the B channel in which the call is being spoken.Release B Channel:When the B-channel is used to transmit the data, the channel must be released, BACP support such a request, but must take into account the requirements of the application, such as a page after downloading 5-10 seconds, users do not have the action, you can think that the user is carefully browsing the page, you can disconnect B channel. After sending and receiving the e-mail, you can disconnect the B channel.

Death Note: hardware and software connection method of ISDN terminal equipment. This article is taken from the manual. This makes it easier for you to focus on setting up conversations. Before installing a device, you need to make necessary preparations. Generally, the Telecommunications Bureau sells or rents the device together. We recommend that you select an external device for easy installation and the Panel has an indicator light, you can use the
