Campus-RS FLEX (CAFLEX) 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. 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).
