Network Access for E1, Serial and
Ethernet
The BXT-M is a modular network access unit and Multiplexer
designed to support IP and Fractional serial data
integration. The unit contains dual E1 links that support
ADD/Drop multiplexing when matched with a two additional BXT-M
units. (see application 1)
Optional data cards allow interface and rate conversion
supporting RS-232, RS-485, G.703 (co-directional) and 10/100
Mbps Ethernet. The BXT-M supports Nx64 data rates when
utilizing the dual port V.35 or 10/100bt Ethernet cards. The
RS-232 port can support Async speeds of up to 19.2Kbps.
Scalable for Multi-Site
Applications
The BXT-M is available is also available in a 2U or 4U high
density chassis. This allows support for additional Serial
and Ethernet Ports at a central location. Up to (5) BXT
cards can installed in the 2U high chassis. This will
support up to (10) BXT-M remote units. Up to (13) BXT cards
can be installed in the 4U high chassis. This will support
up to (26) remote units.
The BXT-M network access units can be utilized with the
higher density BX-10 Integrated Service Platform for
economical high density Ethernet over E1 applications.
