DIDCSU 2912 Overview

Verilink DIDCSU 2912 User Manual
The DIDCSU 2912 does the necessary cross-connections to ensure
that the local area network signal from Building 1 terminates (or
drops) at Building 2, the video circuit is added (inserted), and the
outgoing data stream is sent on to Building 3.
1. Video data from Building 1 is destined for Building 3 but,
because there is no direct connection, is sent to Building 2
over a network line. The node at Building 2 cross-connects the
video data to timeslots on the network line that links Building
2 and Building 3. The video circuit arrives at Building 3.
(Bypass)
2. LAN A in Building 1 uses timeslots on the network line to
Building 2 for transmitting and receiving data from LAN B.
(Drop)
3. LAN C in Building 2 uses timeslots on the network line to
Building 3 for transmitting and receiving data from LAN D.
