Problems solved by technology

For some international channel-associated signaling with multiple branches, it is necessary to occupy multiple E1 interfaces to meet the demand, and the traffic carried by these international channel-associated signaling is small, which reduces the number of users of a single E1 interface. It cannot meet the needs of supporting multiple channel-associated standards and making full use of relay resources in the case of limited relay resources

Abstract

Disclosed are a gateway device, a system and a method for docking a trunk. The method includes: the gateway device configuring a timeslot resource for the signalling with different standards of a docking device; according to the management information about the docking device, encoding an inter-exchange signalling received from a soft switch device into a standard signalling and transmitting the same to the corresponding docking device according to a specified timeslot; and the docking device receiving the signalling with corresponding standard from the gateway device at the specified timeslot according to the configuration information about the timeslot resource of the current device managed by the gateway device.

Description

technical field [0001] The present invention relates to a gateway device of a public switched telephone network (PSTN, Public Switched Telephone Network) and a next generation network (NGN, Next Generation Network), in particular to a gateway device, a system and a method for realizing trunk line (TRUNK) docking. Background technique [0002] T1 and E1 are different physical connection interfaces in the digital network, and their links can use coaxial cables or optical fibers. Among them, T1 is an American standard with a bandwidth of 1.544Mbps; E1 is a European standard with a bandwidth of 2.048Mbps; private lines in my country generally use E1. [0003] The voice digital signal transmitted in E1 / T1 adopts Pulse Code Modulation (PCM, Pulse Code Modulation). For single-channel PCM, the system sampling frequency is 8000HZ, and the sampling interval is 128μs; the sampling interval is divided into multiple time slots (TS, Time Slot) for time allocation. The sampling interval ...
