LED STATUS
DSL1/DSL2 ● Green Loop 1/ Loop 2 synchronization achieved and signal is present.
No errors currently detected, and SNR margin ≥ 3 dB.
● Red Loop 1/ Loop 2 synchronization not achieved, in sync with errors,
or SNR margin < 3 dB.
DSX ● Green DSX-1 signal present and no errors currently detected.
● Red In framed mode, denotes loss of framing or loss of sync at the
DSX-1 input. In unframed mode, denotes loss of signal DSX-1
input.
ALM ●● Off No T1 alarms are active.
● Red Loss of DSX-1 signal from the network.
● Yellow Loss of DS1 signal from the CPE.
ESF/SF ●● Off Unit has detected Unframed data.
● Yellow Unit has detected ESF framing data.
● Green Unit has detected SF framing data.
B8ZS/AMI ● Yellow Unit has detected B8ZS line coding data.
● Green Unit has detected AMI line coding data.

COMPLIANCE
WARNING: Up to –200 VDC might be present on telecommunications wiring. Ensure chassis
ground is properly connected. The DSX-1 interface is intended for connection to
intra-building wiring only.
This product is intended for installation in restricted access locations only and in equipment
with a Type “B” or “E” enclosure.
This product provides span powering voltage (negative only with respect to ground, –190 VDC
nominal, GFI protection < 5 mA) and meets all requirements of Bellcore GR-1089-CORE (Class A2),
and ANSI T1.418-2002. This product is NRTL Listed to the applicable UL standards.
POWERING MODE
The H4TU-C provides –190 VDC span powering voltage and will provide powering to the H4Rs
and the H4TU-R. The –190 VDC span powering voltage is provided on Loop 2.
