1.3 Applications
Because of the variety of plug-in cards available, the applications for Loop-V 4200 MuxMaster are numerous.
Only a few representative ones will be illustrated here. To the extent ports are available, combinations of
illustrated applications are possible.
Important Note on Clock Source: Since the entire system operates on a single clock source, one of the input
signal can serve as the master clock source. Each of the remaining input is presumed to synchronize to this
master clock source. To the extent that the clock of any incoming line can drift with respect to the system
clock, slips, or controlled slips, may occur.
1.3.1 As an ICSU
Figure 1- 2 As an ICSU
In this application, two slots are used in combination to provide the intelligent channel service unit (ICSU)
function. This is used to terminate E1 or T1 lines at the customer site. Performance monitoring and
maintenance functions, such as local and remote loop backs, are available. By using 4 slot-pairs, 4
independent ICSUs can be realized (see note on Clock Source above).
