Summary: This standard specifies the data terminal equipment (DTE) and data circuit- terminating equipment (DCE) interface circuit between the definition. This standard applies at the interface between DTE and DCE interface circuit and interconnect circuit called. These circuits are used to transfer binary data, control signals and timing signals, and appropriate analog signal. This standard also applies to separate the two sides in the middle of the device, and the independent intermediary device can be inserted in between these two types of devices. This standard provides a range of interface circuit can be used, for example: a) synchronous and asynchronous data communication, b) leased line services on the second-and four-wire, point to point or multi- point operation data communication, c) switching network business two-wire or four-wire data communication, d) DTE and DCE between the use of short interconnect cable where the cable for a short description see Chapter 4.

1 Scope

This standard specifies the data terminal equipment (DTE) and data circuit terminating defined interface circuit equipment (DCE) between. This standard Apply between DTE and DCE interfaces and called circuit interconnection interface circuit. These circuits for transmitting binary data, control Signals and timing signals and the appropriate analog signal. This standard also applies to both sides of the separate intermediate equipment, and that separate intermediate equipment You may be inserted between these two types of equipment (see Figure 1). NOTE. If no intermediate devices, select A and B are the same. C is dedicated to select automatic call. The general layout of a schematic diagram of the device 1 The scope of this standard interface circuit can be used, for example. a) synchronous and asynchronous data communication; b) two-wire and four-wire leased line service on point to point or multi-point data communications operations; c) the exchange of data traffic on the network service two or four lines; Between d) DTE and DCE, use short interconnect cable where the cable short description about see Chapter 4. Compliance with this standard DTE/DCE interface, can also be interconnected with the public data network. At this point the interface circuit in the implementation and operation to Additional information on demand in GB/T 11600/ITU-TX.20bis and GB/T 11599/ITU-TX.21bis in. Any actual device, the interface circuit should be from the scope of the standard of appropriately be selected. The actual specific DCE interface circuit is a circuit corresponding to those specified in the standard. In the standard referenced standards specified DCE interchange circuits require only applies to DCE side of the interface. These circuits require Ensure the normal operation, and control or monitoring by the DTE (see 4.5). In Chapter 4 defines the interaction between use and operational requirements of the interface circuit, and an interface circuit. The electrical characteristics of interchange circuits See ITU-TV.10, ITU-TV.11, ITU-TV.12, GB/T 3455/ITU-TV.28, ITU-TV.31 and ITU-TV.31bis. Mechanical characteristics of the interface Refer to GB/T 15125/ISO 2110 (25-pole), GB/T 17559/ISO /IEC 11569 (26-pole), ......
