Multiport Data/Voice Interface Module

Campus-RS FLEX
Campus-RS™ FLEX is an interface module that installs directly into a Campus-RS remote or
Campus-RS Star concentrator and provides a multiport local interface capable of supporting
a wide range of concurrent data, voice and video applications. Campus-RS FLEX supports a
line speed of 1.544 Mbps (T1) and provides the capability to allocate this bandwidth between
the single DSX-1 port and the two serial data ports. The DSX-1 provides support for up to 24
voice channels over a T1 backbone. The two serial data ports support a variety of standard
physical interfaces, including RS-449, RS-530, RS-530A, V.35, and X.21, which can be
configured to operate at n x 56/64 kbps fractional data rates.
With a Campus-RS FLEX installed within a private enterprise network, users can be provided
with instant access to advanced digital services including LAN interconnectivity, video
conferencing, and PBX extensions all while using the existing copper infrastructure. With
Campus-RS FLEX, many of the networking needs of the private enterprise can be satisfied
without the need for multiple WAN connections. Interface-specific settings can be accessed
and configured from the front panel of the Campus-RS remote or Star concentrator and SNMP-
based management is enabled via the Campus-RS Star CMU (Campus Management Unit).
Features:
• Supports voice, data and video applications
• Enhances incoming T1 circuits
• Interoperable with standard network equipment
• Simple installation and configuration
