TSU 120 CONFIGURATION APPLICATIONS
The following example illustrates possible configurations of
TSU 120 applications.
Router, PBX, Video Conferencing Applications
The base Nx54/64 provides a V.35 interface to a router. The
PBX is interfaced to the TSU 120 with the base DSX-1 interface.
An OCU DP module and OCU DP plug-on board provide two
Switched-56 circuits for video conferencing. The 10BaseT port
allows SNMP network management over the LAN (TSU 120e
only). See Figure 1-2.
