Asymmetric Digital Subscriber Line (ADSL
and ADSL2+) is the prominent DSL service
offered by telecom carriers and continues to
be delivered in conjunction with Plain Old
Telephone Service (POTS).The extraordinary
demand for ADSL service has accelerated
the demand for higher-density equipment.
Furthermore, as the demand for VDSL2
grows, both splitter and non-splitter appli-
cations will be required.
The ADTRAN
®
Total Access
®
3050 is
designed to meet this demand by providing
the ADSL/VDSL and POTS signal splitting/
combining function. It is configured to inte-
grate with the Total Access 3000 DSLAM using
28 Octal splitters or cut-through modules per
chassis and is ANSI T1.413 compliant. The
shelf is a solid metal design with a latched,
hinged, metal front cover for easy access. A
filtered airflow is maintained from the front of
the chassis. The Total Access 3050 utilizes a
four-pole splitter design and no active
components are on the standard splitter
modules. No direct current (DC) blocking
capacitor is required.
ADTRAN designs products that maximize
functionality for its carrier customers. In that
regard, the Total Access 3050 accommodates
other service cards such as SHDSL, IMA,
IDSL, DS1 FR, CES, and DSX-1. These can be
utilized by installing a cut-through module
instead of a splitter module in the
corresponding shelf.
The unit uses make-before-break connec-
tors to maintain POTS connectivity and
operate normally without a splitter module
installed. Connection to the Total Access 3000
DSLAM is established using 64-pin connec-
tors.
The rear of the shelf has twenty 50-pin and
eight 64-pin amp connectors, one DB-25
connector for Metallic Test Access (MTA), and
one RS-485 wire-wrap bus for daisy chaining
splitter shelves. There is a standard power
connector for –48 V, –48 V return, and chassis
ground.
The system will also support MTA. With
the addition of the metallic test control
module and modules with MTA, the shelf will
interface with metallic test heads and provide
access to the loops. There are MTA modules
for both ADSL and cut-through applications.
