DS2149Q+T&R is a cellular access network interface (API) from Data2149 that combines the interoperability of tri-channel (T1,T3,E1) with the robustness of Airspan microwave radios and the throughput of hybrid IP/TDM networks. It serves as a multi-modal interface between base stations and their respective local loop networks, providing a high-performance and scalable solution for end-users to access wireless services.

The DS2149Q+T&R is used in the interface communication field. Its main application is in the telecom sector, where it is used to provide access to wireless services over a variety of mediums. The device is capable of connecting to the local loop of a cellular base station, allowing access to the internet, media streaming services, and VoIP calls over a secure, reliable, and high-performance connection.

The DS2149Q+T&R utilizes a common channel (T1/T3/E1) to communicate with remote access devices over a hybrid connection that integrates both IP and TDM traffic. This hybrid infrastructure allows for increased throughput, as data can be transmitted simultaneously over both mediums. Additionally, the device is designed for interoperability, supporting a variety of transmission technologies such as GSM, GPRS, EDGE, and CDMA, among others.

The working principle of the DS2149Q+T&R is relatively straightforward. Its primary duty is to act as an interface or gatekeeper between the cellular base station and its local loop network. This is done by connecting to the local loop network via T1/T3/E1 or through the hybrid IP/TDM connection. The device ensures secure and reliable access to the base station by encrypting data traffic and performing regular monitoring on the connection.

Once the DS2149Q+T&R has established a connection with the local loop and the base station, it maintains the connection and facilitates data transmission in both directions. Inbound traffic is forwarded to the base station and outbound traffic is received from the base station and forwarded to the local loop network. This allows wireless services, such as IP and VoIP calls, to be accessed over the cellular network.

Overall, the DS2149Q+T&R is a powerful tool for providing secure and reliable access to wireless services via a variety of mediums. Its hybrid IP/TDM infrastructure and interoperability with a multitude of transmission technologies make it a great solution for interface communication in the telecom sector.
