ADTRAN HTU-C NB Installation And Maintenance Practice page 13

This device complies with Part 15 of the FCC rules. Operation is subject to the following two
conditions:
1. This device may not cause harmful interference
2. This device must accept any interference received, including interference that may cause
undesired operation.
Changes or modifications not expressly approved by ADTRAN could void the user's authority
to operate this equipment.
Voltages up to –200 VDC with respect to ground may be present on
the HDSL telecommunications conductors. Voltages up to 200 VDC
may be present between individual HDSL telecommunications
conductors.
Per GR-1089-CORE the HDSL System is designed and intended for
installation as part of a Common Bonding Network (CBN). The
HDSL System is not designed nor intended for installation as part
of an Isolated Bonding Network (IBN).
Per GR-1089-CORE Section 9, the HTU-C NB/WB for Litespan
does not have an internal DC connection between battery return
and frame ground. As such, it may be installed in a DC-I (isolated)
or DC-C (common) installation. For installations where other cards
or the host system have internal connections between battery
return and frame ground, the system would be intended for
deployment only in a DC-C installation.
The HDSL port is classified as Type 1, 3, and 5, as defined in
Appendix B of GR-1089-CORE Issue 4, and meets the lightning
and power fault criteria with any primary protector that meets any
of the voltage limits of GR-974-CORE or GR-1361-CORE (for
example., carbon blocks, gas tubes, solid states, etc.).
