The concept of duplex communication, which allows for simultaneous transmission and reception of data, is inherent in the design of E1 circuitsDifference Between E1 and T1 However, the management of time slots plays a pivotal role in how this duplex operation is realizedIn theE1frame format, a channel (ortimeslot) is called a TS, and the 32 channels are numbered TS0 to TS31. Two channels are used to establish and maintain  Time Division Duplex (TDD) is a specific form of TDM where, within the same TDM frame, certain slots are designated for the uplink direction (from end nodes to the network) and others for the downlink direction (from the network to end nodes)Multi-channel monitoring approach of E1 streams This contrasts with Frequency Division Duplex (FDD), which uses separate frequency bands for simultaneous transmission and receptionTimeslotassignment is accomplished according to the Data Port speed and manual setting of DIP switches.
