Installation
Configure Line-Link Modules
Summary: Ensure the
DIP
switch setting on each TC4150 Line-Link Module (LLM) is in accordance with
system requirements.
Equipment required: Small flashlight, six-inch long, small shank (#l), flat-bladed screwdriver, pliers.
Step 1. Refer to the
Physical Number Layout Planning Worksheet
and determine which LLM’s are
required to support the physical numbers noted on the
System Planning Worksheet
for
Central Equipment Phone LLM’s.
Step
2. Go
to the front of the system cabinet and locate the LLM’s. LLM 0 is in the Central Control
Assembly (TC4001) and all other LLM’s are immediately below in the expansion chassis.
Step 3. Using the flashlight, peer through the inspection port on the left side of each
LLM
and locate
the DIP switch behind the ribbon cable connector. Compare the factory set
DIP
switch
settings with the LLM
DIP Switch Settings Table
below, keeping the following in mind:
The DIP switch setting provides the system address for the range of physical numbers
supported by a particular LLM.
The LLM number (O-31) is determined by the physical numbers required, not the
number of LLM’s in the system. Refer to the column marked
PHYS.
in the table below
for the range of physical number associated with each LLM.
0
means
the switch is down.
1 means
the switch is up.
Step 4. If setting must be changed, use this figure as a guide to
toggle the switches as necessary. This can be done in one of
two ways: Insert the screwdriver through the inspection
port; or, go to the rear of the cabinet and remove the LLM
after straightening the retaining tabs which hold it in place.
Step 5. On the chassis near the ID strip, mark the LLM with the first
and last physical numbers it supports and remove any con-
flicting factory markings.
