PRODUCT OVERVIEW
The ADC®HiGain®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.
NEW FEATURES
•Four-span range with three doublers (14.6 km, 0.51 mm /24 AWG)
•Four line-powered spans (three doublers and a remote)
•Low line-power option (140 V) for circuits with a single doubler
•Reduced power consumption
•Ultra-low wander (Stratum 1 compliant)
•Selectable Power Feed (PWRF) modes: AUTO, HIGH and LOW
•HDSL grounded loop detection
•BER alarm options
•ERU Loopback screen
•Inventory Screen (for Circuit ID and unit IDs)
•Default setting screen option
STANDARD ELU FEATURES
•Front panel features:
–HDSL SNR margin display
–G.703 splitting and bridge access
–Status LED
–RS-232 craft port for connection to a maintenance terminal
•Compatible with Span Terminating Shelf (STS) high-density shelves
•Selectable loopback activation codes
•Network Management and Administration (NMA) interface
•Lightning and power cross protection on HDSL interfaces
•Full duplex 2B1Q HDSL transmission on two pairs each at 1040 kbps
•Margin threshold alarmELU-319 List 5E and List 6E

APPLICATIONS
HiGain systems provide a cost-effective, easy-to-deploy method for delivering G.703 E1 High Capacity Digital
Service (HCDS) over metallic pairs.
•The service is deployed over two unconditioned, non-loaded copper pairs, yet it demonstrates a quality that
is competitive with fiber optics.
•Conventional, in-line, E1 repeaters are not required.
•Cable pair conditioning, pair separation and bridged tap removal are not required.
Each loop has no more than 35 dB of loss at 260 kHz, with driving and terminating impedances of 135 W.
Table 1 provides a “loss”guide for the various cable gauges at 260 kHz and 135 W. Table 1 applies to the HDSL
cable pairs between the ELU,ERU, and EDU modules. In the absenceof specific insertion loss measurement data,
add 3 dB for each bridged tap and 1 dB for each cable gauge change.
The E1 operating ranges on unimpaired cable pairs are shown in Table 2 as a function of cable gauge and
average margin.
In general, HiGain systems:
•Operate with any number of other E1, POTS, Digital Data Service (DDS) or other HiGain systems sharing
the same cable binder group.
•Can be used with customers requiring G.703 service on a temporary or permanent basis.
•Provide a means of quickly deploying service in advance of fiber-optic transmission systems.
With a HiGain system, service can be provided within hours. Fiber-optic systems can be installed incrementally
and cut-over from the installed HiGain system when convenient to do so.
