One implementation butt trunk gateway device, system and method

TECHNICAL FIELD

Background technique

T1 and E1 digital networks are connected to different physical interfaces, which link may preclude the use of coaxial cable can also preclude the use of optical fiber. Where T1 is the US standard, the bandwidth is 1.544Mbps; E1 is the European standard, the bandwidth is 2.048Mbps; generally preclude the use of leased lines are El.

The transmission of digital voice signals preclude E1 / T1 pulse code modulation (PCM, Pulse Code Modulation). For single-channel PCM, sample system adopts frequency 8000HZ, preclude the sample interval is 128 s; that preclude sample interval is divided into a plurality of time slots (TS, Time Slot), to be allocated time. E1 preclude the sampling interval is divided into 32 time slots, T1 preclude the sampling interval is divided into 24 time slots.

Digital trunk road E1 / T1 supports preclude the use of multi-standard channel associated signaling, and each signaling standards are not uniform. As RITU-T standard Q.400-Q.490 defines the R2 signaling standard. Different countries and regions have their own signaling standard implementation, such as China has Nol signaling standards, Europe, Latin America and some developing countries such as Brazil and Argentina have R2 signaling standards; and, because each country preclude the use of the device is not unified, there are no uniform standards.

Currently relay resource group to group management units, which is a primary rate of E1 / T1 interface can only support one standard channel associated signaling. For some international channel associated signaling There are many situations branch, you need to take multiple E1 interfaces to meet demand, while these international traffic carried by the channel-associated signaling and smaller, thus reducing the single user interface E1 the amount can not be met under the limited resources available to support a variety of trunk road with the standard relay needs to make full use of resources.
