ADTRAN�s Total Access �
Services group has combined the Total Access OPTI-3 � OC-3
Multiplexer with the ADTRAN Total Access MX2800 � M13
Multiplexer and the ADTRAN NIU-3 DS3 NIU in a single Outside
Plant (OSP) Cabinet to create the ADTRAN Total Access Cell
Site Cabinet.
The Total Access OPTI-3 provides a cost-effective,
interoperable and compact solution for delivering DS3 services
via SONET-based OC-3 fiber interfaces. The Total Access OPTI-3
delivers three DS3 services from a SONET multiplexer operating
in the terminating mode. The Total Access MX2800 uses one DS3
from the Total Access OPTI-3 and delivers up to 28 DS1s to
complement two DS3s available from the Total Access OPTI-3.
The NIU-3 allows full diagnostic and loopback test capability
to the customer premises. The cost-effective delivery of
multiple DS3s and DS1s combined in an OSP cabinet provides an
ideal solution for today�s higher bandwidth needs for data and
voice traffic at cell sites.
In this application a Total Access
Cell Site Cabinet is delivered from a Central Office (CO) that
contains a SONET Add-Drop Multiplexer (ADM). The CO delivers
an OC-3 signal to the Cell Site Cabinet via an OC-3 fiber
connection. Upon receiving the OC-3 signal from the CO, the
Total Access OPTI-3 demuxes the signal into the three DS3
signals. Two of the DS3 signals are available for cellular
providers in the Cell Site, while the third DS3 is used by a
Total Access MX2800 to provide 28 DS1s. By combining
leading-edge technology to solve bandwidth delivery issues,
ADTRAN has provided a compact and cost-effective solution for
delivering DS3 and DS1 services to cell sites.
The Total Access Cell Site Cabinet using ADTRAN innovative
solutions, the Total Access OPTI-3 OC-3 Multiplexer, the Total
Access MX2800 M13 Multiplexer, and the NIU-3 provides
cost-effective solutions for bandwidth delivery to cell sites.
