1. GENERAL

This practice is an installation and maintenance
practice for the ADTRAN E1 HDSL Encapsulated
Regenerator (REG). Figure 1 is an illustration of
the REG. REG equipment features include:
• Up to 4.75 km over 0.5 mm wire in each
direction
• Span powered from LTU
• 2B1Q line coding
• Lightning protection
• Waterproof encapsulated case
• Enhanced provisioning, performance
monitoring, and diagnostics
• CISPR22 Class A
• CE Mark
The ADTRAN E1 HDSL Encapsulated REG is used
to extend the effective range of an ADTRAN
HDSL-based E1 circuit. It is capable of doubling
the deployment range of standard HDSL, full-range
loops on both sides of the REG extending the digital
subscriber loop serving range up to 9.5 km of
0.5 mm twisted pair wire, using a centrally located
unit.

One REG can be used in conjunction with any span
powering E1 HDSL transceiver unit for the
exchange office (LTU) and E1 HDSL transceiver
unit for the remote end (NTU). Compatible
ADTRAN HDSL transceiver units are as follows:
• P/N 1245011LX, E1 HDSL LTU
• P/N 1245031L1, E1 HDSL NTU Circuit Pack
• P/N 1245032L1, E1 HDSL NTU Standalone
• P/N 1181102LX, E1 Total Access LTU
• P/N 1245035L1, E1 HDSL NTU Circuit Pack
There are no manual option settings on the REG.
REG operating power is derived from an LTU,
independent of line impedance or wire diameter.
The operating power from the LTU is also used to
span power the NTU.
The REG operates at line losses up to 27 dB at
150 kHz, in both directions from the extender and
regenerates the 2B1Q signals to meet the
transmitted power spectrum of ETSI TS 101 135.
The REG does not require a secondary
environmental apparatus case. Because it is
encapsulated in a polyurethane compound, this
device is waterproof and can be mounted on a pole,
in a pedestal, in a manhole, or other suitable
location.
