System Planning
Assign Physical Numbers
Physical numbers are used by system software to keep track of equipment
connected
to each
of the 5 12 possible lines; therefore, each TC4150 Line Link Module (LLM) and each
TC4110
(SC25)
and TC4120 (SCC25) Speaker Control line in the system has a physical number. The
first step in assigning physical numbers is determining how many lines are required from
Line-Link Modules (LLM) and Speaker Contol (SC) boards. Then, physical numbers can be
assigned using the Physical Number Iayout Worksheet.
step 1.
Step 2.
Step
3.
Refer to the
Quantity column
of your
System Planning Worksheet
and enter the number of
LLM lines required for each of the following:
TC4160
VCM (additional VCM’s only: VCM 1 has a dedicated LLM line.)
TC4400 Console (1 LLM line is required for the Console)
Trunks/TC4171 COA’s
(1 LLM line per
trunk/COA)
Key Phones (1 LLM line per unique Key Phone Line: Do not multiply by
the number of Key Phones if they all use the same lines.)
Administrative (1 LLM line per Administrative Phone)
Multi-Link Staff (1 LLM line per phone: Refer to your Staff function defini-
tions for the quantity of Multi-Link phones required.)
A Phone SC line is required for each Single-Link Staff Phone. Refer to your definition of Staff
Functions
for the quantity of Single-Link phones required and enter that number on the
appropriate function line under
Phone SCC25.
A Speaker
SC
line is required for each Speaker. Refer to the
Quantity column
of your
System Planning Worksheet
and enter the number of Speaker SC25 lines required for each
function.
Step 4. Make a copy of the
Physical Number Layout Worksheet
and define a set of physical num-
bers for each function, keeping the following in mind:
Assign physical numbers in a way that makes maximum use of resources. This will
help minimize system costs.
Group like equipment together and add physical numbers to allow room for system
growth. This is especially important for Trunks/COAs, Administrative Phones, and
Multi-Link Staff Phones because they use LLM lines, which are generally more limited
in number than SC lines.
Use a colored pencil or some other method to code groupings of physical numbers by
function. This graphic depiction will allow a quick assessment of free LLM and SC
lines.
After completing the physical number assignment, determine if additional lines can
be added to any of the groups from the unused lines at the end of the physical
number range.
