As a kind of network hardware device, the relay interface card is mainly used to realize the bidirectional forwarding of physical signals between two or more network nodes. The following is a detailed summary of the main features and information of the trunk interface card:

Concept and function:

The trunk interface card (such as the 6E&M board) is a device that connects network lines. It works at the first physical layer of the OSI reference model and transmits information bit by bit on the physical layer of two nodes to replicate, adjust, and amplify signals to extend the network length.

It mainly solves the problem of signal distortion caused by loss in the signal transmission process, through regeneration and amplification of the attenuated signal, 05704-A-0131 maintains the same as the original data to ensure the accurate transmission of data.

Functions and Features:

The 05704-A-0131 supports the E&M relay function to access and process multiple (such as 6 channels) 64kbit/s signals.

E&M signaling supports various types, such as Bell1, Bell2, Bell3, Bell4, and Bell5 signaling.

Provides abundant alarm and performance logs for maintenance and fault location.

Indicators are displayed on the panel to display system status and port status.

Interfaces and connections:

It is equipped with multiple E&M interfaces (such as 6) for receiving and sending E&M signals to complete the audio signal transmission function.

The interface usually uses an RJ45 connector, which conforms to the G.712 interface standard, and the interface rate is 64Kbps.

05704-A-0131 supports multiple interface protocols and routing modes, such as Bell1 to Bell5.

Application environment:

It is commonly used for analog trunk access in small and medium-sized enterprises and enterprise branches to perform low-rate data exchange and audio signal transmission.
