TScan
The 3192 H4TU-C is equipped with TScan
TM
, which
provides data retrieval and diagnostic capabilities for
remote management of DS1 circuits. TScan allows
provisioning, performance, and event history infor-
mation to be retrieved by the test center via the Facility
Data Link (FDL). In addition, TScan can be used to
determine the nature and location of faults on DS1
trouble circuits. TScan is accessible only through the
remote test center.
TScan is a patent-pending, single-ended, diagnostic
routine residing on a host server at the central test
facility. TScan issues commands and retrieves data via
FDL from the H4TU-C. TScan performs the following
functions (see
Figure 2 ):
• Detection and location of an open, one or both
conductors
• Detection and location of a short between Tip and
Ring
• Detection and location of a ground fault from either
or both conductors
• Detection of foreign voltage
• H4TU-C self diagnostics
• Ability to remotely detect the presence or absence
of a ground connection in the remote mount.
Figure 2. TScan Diagnostics
TScan allows operators to integrate this capability
across multiple computing platforms with existing
operating systems.
NOTE
For implementation of TScan please contact
your local ADTRAN sales representative.
Compliance
Table 2 shows the compliance codes for the 3192
H4TU-C. The 3192 H4TU-C is to be installed in a
restricted access location and in a Type “B” or “E”
enclosure only.
WARNING
Up to –200 VDC may be present on telecom-
munications wiring. The DSX-1 interface is
intended for connection to intra-building
wiring only. Ensure chassis ground is properly
connected.
The 3192 H4TU-C provides span powering voltage
(negative only with respect to ground, –190 VDC
nominal, GFI protection < 5 mA) and meets all require-
ments of Bellcore GR-1089-CORE (Class A2) and
ANSI T1.418-2002. This product is NRTL listed to the
applicable UL standards.
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.
