These two High Level Muxes, Model 1 and 2 are
interchangeable. A HLM with part # 101-
115450-xxx can replace a HLM with part #
102-115450-xxx and vice versa.
Caution: When replacing modules, the spare
unit must have the same option # as the one
that is being replaced.
HLM Low/Medium
Capacity
Used in Low/Medium capacity radios: 8xDS1,
16XDS1, 28xDS1 and DS3.
101-115071-xxx used in a terminal
configuration. Terminal options:
Option 001 HLM 8xDS1
Option 003 HLM 16xDS1
Option 005 HLM 28xDS1
Option 007 HLM DS3
102-115071-xxx used in a repeater
configuration. Repeater options:

Option 006 HLM 28xDS1
103-115071-xxx supports both configurations
for terminal and repeater. Terminal options:

A Model 2 (part # 102-115071-xxx) cannot
replace Model 1 (part # 101-115071-xxx). This
is not possible because Model 1 supports the
terminal options and Model 2 supports the
repeater options.
The new HLM model 103-115071-xxx could
replace a Model 1 with part # 101-115071-xxx
or a Model 2 with part # 102-115071-xxx as
long as they have the same option number (the
last three digits of the part #). The new HLM
Model 3 supports both options for the terminal
and repeater.
A HLM Model 1 or 2 can be used instead of a
Model 3 if they have the same option numbers
(the last three digits of the part #).
Caution: When replacing modules, the spare
unit must have the same option # as the one
that is being replaced.
