EXTENSION CUTDOWN SHEET

Extension Cutdown Sheet Configuration (Figure 3-4)
Due to the inherent flexibility of the universal PCB slot configuration, standard cutdown sheets for extension
cabling do not apply.
For example, given that the CPU provides 8 digital station ports (1-8) and 2 analog ports (9-10), an 8ESIU-S
installed in slot #3 would use extension numbers 311-318, if two 8ESIU-S PCBs or 4SLIU-S with the
4SLIDB-S PCBs were installed in the cabinet in the order below, the numbering plan would correspond as
follows:
To determine extension assignments for the system cutdown, the installer must identify the following in
order:
● Order of installation (if additional PCBs installed after initially powering up)
●
Slot used
● PCB type (8ESIU-S, 4SLIU-S, 4SLIDB-S)
● Connector
To determine where any group of extensions is installed, note the order of install, slot, PCB connector and
PCB type.
On the following page is the extension cutdown sheet (Figure 3-4). Make as many copies as you need. Be
sure to keep careful records of your installation.
To install VoIP extensions, refer to LAN DEVICES (page 6-1) for more details.

Note: The order in which the extension PCBs (8ESIU-S, 4SLIU-S, 4SLIDB-S) are installed
determines the assigned extension number.
