1.5.1.1 CM-5RB Function Displaying
When the CM-5RB display is blank or when a function is displayed, press down on the GROUP toggle
switch to view the name of the currently selected group. Once the current group name is displayed,
press down on the GROUP switch again to select the next group or press up to select the previous
group, until the desired group is displayed.
Press down on the SET/NEXT switch to display the first function in the currently selected group. Once
a function appears, press down on the SET/NEXT switch repeatedly until the desired function is
displayed.
The bi-level indicator light set to the right of the function display indicates the status of the currently
displayed function. If the top (green) light is on, this function is active. If the bottom (red) light is on,
the function is not active.
1.5.1.2 CM-5RB Function Setting
To turn on a function that is not currently active, press up twice on the SET/NEXT switch while that
function is on the display. Pressing up once causes the top (green) light to blink, indicating that a
setup change takes place if the SET/NEXT switch is pressed up again. Actually pressing up on the
SET/NEXT switch a second time causes the green light to turn on continuously, indicating that the
selected setup parameter has been changed to the currently displayed setting. If a function is already
active, pressing up on the SET/NEXT switch again causes no status or setup changes.
For example, if the display shows ESF while frame format is set to SF, the red light is on. Pressing up
on the SET/NEXT switch once causes the top (green) light to blink. Pressing up on the SET/NEXT
switch a second time actually changes the current T1 framing format from SF to ESF – the red light
goes out, and the green light stays on.
It is important to note that some setup functions are mutually exclusive; activating one function
automatically deactivates another, such as
● Line code (you can set the line code to AMI or B8ZS but not both).
● Frame format (you can set the frame format to SF or ESF but not both).
Other functions are not mutually exclusive, such as the CM-5RB Line (LnLB) and Equipment (EqLB)
loopbacks in the LPBK group, which may both be activated at the same time.
1.5.2 Indicator Lights
In addition to the indicator lights on the CM-5RB common module, four system status indicator lights
located on the power supply are visible when the front cover of the shelf is on (Figures 1-1 and 1-2).
Table 1-1 summarizes the meaning of the indicator lights on both the CM-5RB common module and
the power supply. For all the lights, “on” means the light is on continuously; “blink” means a rhythmic,
one-half second on, one-half second off pulse; and “flash” means erratic flickering. Table 2-1 in
Section 2.1.3.7 gives more details for CM-5RB indicator lights, and Table 2-8 in Section 2.1.5 gives
more details for power supply indicator lights.
