Line Unit ELU-819 List 1 installs in any
3192-compliant chassis and interfaces with the HiGain-ETSI Universal
Termination Units UTU-801 List 5, UTU-802 List 5, and UTU-804 List 5.
The ELU-819 and the UTUs provide the Central Office (CO) and remote
terminal (RT) sides of a repeaterless, High bit-rate Digital Subscriber Line
(HDSL), respectively. The RT provides both E1 (G.703) and data interface
(V.35, V.36, RS-449, X.21, or RS-530) ports to the customer (see
).
The ELU-819 accepts the respective payloads through a E1 port from a
multiplexer or a cross-connect shelf and transports it to the UTU-801 List 5,
UTU-802 List 5, or UTU-804 List 5 at a maximum data rate of up to 2.048
Mbps. An internal time-slot assignment function splits the E1 bandwidth
between these two ports as two Nx64K tributaries.

Typical ELU-819 List 1 Application (E1 to Dual-Port Operation)
For the ELU-819 List 1 to support E1 transmission over HDSL
lines at the customer remote, the ETSI Remote Enclosure
ERE-811 List 2 and the UTU-801 List 5, UTU-802 List 5, or
UTU-804 List 5 (ETSI cards) must be used at the remote
location.
