The Alcatel 2753 MainStreet
The Alcatel MainStreet access
portfolio is feature-rich and comprehensive, comprising multiservice
access platforms (MAPs), integrated access devices (IADs) and
network termination units (NTUs). With over 250,000 nodes deployed
worldwide, it is considered the most successful digital overlay
platform ever built.
The Alcatel 275x MainStreet Data
Termination Units (DTUs) are used in many applications that require
secure, highly reliable data such as automatic banking machines,
lottery terminals and alarm monitoring applications. The Alcatel
275x MainStreet DTUs maximize performance from installed copper
The Alcatel 275x MainStreet DTUs
offer an attractive alternative for providing services of up to 128
kb/s to remote sites, ideal for offering services from a central
site to remote locations.
Three types of DTUs are available
- the Alcatel 2751, Alcatel 2752 and Alcatel 2753 MainStreet DTUs
with TIA/EIA-232 (RS-232), X.21 and V.35 user ports, respectively.
All three DTUs share a common network port and can be mixed and
matched on the same 12-port line card
(90-6396-01 also in stock) . Subrate (<64 kb/s) data is
supported and can be multiplexed onto the same DS0. This
multiplexing of data allows for efficient utilization of bandwidth
and real cost savings. Both the 6- and 12-port line cards can be
installed in the Alcatel 3600 MainStreet and Alcatel 3600+
MainStreet Multiservice Bandwidth Managers.
This family of DTUs supports full
redundancy on the network interface, the line and the DTU itself.
