Description
The T200 H4TU-R can be deployed in circuits using
one H4TU-C, one H4TU-R, and up to two H4Rs.
The T200 H4TU-R terminates local loop HDSL4
signals originating from the Central Office (CO) unit
and transforms the HDSL4 signal into traditional DS1
signals to be delivered to the customer.
The T200 H4TU-R can be used with any H4TU-C to
complete an HDSL4 circuit with up to two H4Rs. Local
power is provided through the enclosure.
NOTE
This unit is intended for Local Power Only. If
a span powered unit is needed, refer to P/N
122x426L2.
The H4TU-R is a T200 mechanics card which will fit
Type 200 or Type 400 mechanics enclosures, as listed
in Table 2. This table also provides reference infor-
mation on the ADTRAN enclosures.
1 In all applications the H4TU-R must be installed in NEBS
compliant and UL listed enclosures to insure full compli-
ance with this unit.
2 ADTRAN’s T200 Dual-Mount housing (P/N 1245034L1)
is required when using the T200 H4TU-R for HDSL Loop
Support System (H-LSS
TM
) protection circuits.
Compliance
Table 3 shows the compliance codes for the T200
H4TU-R. This product is intended for installation in
equipment with a Type “B” or “E” enclosure.
This product meets all requirements of Bellcore GR-
1089-CORE (Class A2), ANSI T1.418-2002 and is
NRTL listed to the applicable UL standards.
2. INSTALLATION
After unpacking the unit, inspect it for damage. If
damage is discovered, file a claim with the carrier, then
contact ADTRAN. Refer to the Warranty and Customer
Service section in this practice. The settings on the
H4TU-C are encoded and transmitted to the T200
H4TU-R once the circuit has achieved synchronization.
There are no switch settings on the T200 H4TU-R.
To install the T200 H4TU-R, perform the following
steps:
1. If present, remove the Access Module Blank from
the appropriate access module slot of the
enclosure.
2. Hold the T200 H4TU-R by the front panel while
supporting the bottom edge of the module.
3. Align the module edges to fit in the lower and
upper guide grooves for the module slot.
4. Slide the module into the slot. Simultaneous thumb
pressure at the top and at the bottom of the module
will ensure that the module is firmly seated against
the backplane of the enclosure.
WARNING
Up to –200 VDC may be present on telecom-
munications wiring. Ensure chassis ground is
properly connected.
