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.
