3. Connect the E1 Line(s). Plug the E1 cable into the RJ21 connector for the chosen slot on the back of the IP DSLAM. The EAM2000-12 will connect with remote E1 modems at distances up to 6,000 feet before requiring an E1 repeater. For each port being connected to a remote E1 modem, verify that the E1 link has been established; the E1 LK LED for that port will show steady illumination to indicate the connection has been made. Link up should occur within 20 seconds depending on the quality, g

Although all 31 channels continually run at 1,984 kbps, the Timeslot configuration for each port determines NOTE how many of the channels will be receiving data for that port. Ports configured to operate as fractional E1 lines require contiguous timeslots, as indicated in the table above. Frame Type Frame type is the E1 data encapsulation method. A frame consists of 248 bits (8-bit samples of each of the 31 E1 channels plus a synchronization bit) transmitted at a rate of 8,000 frames per sec
