2. Fixed Link Connection to Sitespan

The figure below shows a typical set-up for connecting the CT site to a remote management

site using a 2Mbit/s E1 . The CT rack connects to a 4 port Mux (Sprint 2) that concentrates

the outputs of the modem shelves into a 64kbit/s output. This output can connect over a 64K

link to another Mux or go through a further Micromux to put the information on an E1 Link.

The E1 link can be further aggregated onto a high speed link using an Optical Mux (LS120).

The reverse process takes place at the remote site. The outputs of the 4port Mux connect to a

Digiboard Port expansion card located in the server PC. The server and Client (equipment

View software are both run on the same PC.
