ELU-319 List 5E and List 6E are the Central Office (CO) side of a repeaterless, G.703 E1
transmission system. When used in conjunction with a HiGain Remote Unit (ERU) the system provides
2.048 Mbps transmission on two unconditioned copper pairs for delivering G.703 E1 High Capacity Digital
Service (HCDS). This line unit can be used in applications with or without EDUs.
The HCDS includes loops up to 3.7 km of 0.51-mm wire or 2.7 km of 0.4-mm wire, including bridged taps. The
HiGain system uses HDSL transmission technology as recommended by Bellcore TA-TSY-001210.
