E1 line multiple access methods The system center equipment IDM MSAP-CP and IDM MSTP155-16 devices provide a wealth of E1 interfaces, compatible access to the local transmission network.
The E1 interface of this series of devices supports a variety of signaling access methods, including No.7 signaling, No.1 signaling, V5.2 signaling, and PRI signaling, which can be easily accessed to the local PSTN network for convenient fixed-line, GSM phone access.
It can be connected to E1 microwave equipment to perform line-of-sight wireless transmission. At the same time, it can access pseudo-circuit simulation equipment to implement E1 signal access to the IP network so that voice services can be transmitted over the IP network.
Supports access to satellite E1 signals and in the case of a G.SHDSL transmission line, twisted-pair access to E1 services is available.
The E1 line serves as a transmission line and provides a backup protection function for the optical line transmission service. When an optical line fails, the E1 line can be used to transmit voice and Ethernet services on the device. Its application is shown in the figure below. 
Diagram of E1 backup protection line Multiple access methods for voice lines In this system, the central equipments IDM MSAP-CP, IDM MSTP155-16 and radio dispatching gateway equipment IDM 60N provide rich 64K interfaces, including interfaces such as FXO, FXS, and EM. Can access to the telecommunications network, access GSM phones, satellite phones can also be accessed, but also through the analog trunk access PSTN network, access to IP voice gateway devices, to achieve communication with the IP phone.
The system accesses the IDM 60N equipment through the E1 line to realize remote voice control and scheduling functions. At the same time, the IDM 60N equipment can cascade the leased network through the E1 line to expand the network size and increase the system customer capacity. The networking method is shown in the figure below. As shown. 
Diagram of the remote command and dispatching application of the chain network The characteristics of this system voice scheduling:
Each radio frequency of the IDM 60N can be selected. When the frequencies of the integrated scheduling network management stations in the SDH network are the same, all handsets can perform half-duplex communication. When the radio frequencies are inconsistent, the handset can be grouped to perform half-duplex operation. Communication, but does not affect the communication between the outside line and the wired terminal and the handset, the packet communication of the handset facilitates the scheduling between different departments;
 When an outside line enters into remote scheduling through a telecommunication network, the wired terminals and handsets connected to the integrated dispatch network management in the SDH network can receive voice information to implement half-duplex communication; when the outside line finishes speaking, the wired terminal With the handset, you can grab the button to speak and talk over the entire network.
 Each integrated dispatching network management system can support up to 24 wired terminals to access simultaneously. Wired terminals can perform half-duplex voice communications to all networked handsets and wired terminals, facilitating leaders to conduct remote command and dispatch in the office.
