F. Make DS1 Connections
The O3-4D1L3 module has a female AMP CHAMP front-panel connector that is designed
to be used with a screw-lock connector hood. Pulsecom cable AMP-MSL/U24Sxxx
should be used. See Table 6, Procedure 4, and Figure 1.
Procedure 4. Making DS1 Connections
STEP
ACTION
1
Before plugging in the DS1 cable, activate the DS1 circuits that are to be used
(1, 2, 3, and/or 4) by setting the appropriate front-panel switch(es) to the EN
(enable) position.
2
Verify that the DS1 indicators are red. If a DS1 indicator is off, yellow, or
green, the unit is defective and should be replaced.
3
If the Pulsecom AMP-MSL/U24Sxxx assembly is used, refer to Practice
Section 1636.
4
If the far-end DS1 cable connection has already been made to an active DS1
device, the DS1 LED for each active DS1 should turn green or, if there is a
far-end trouble, turn solid yellow. If the DS1 indicator remains red:
•
Verify that the cable is in good condition.
•
Verify that the cable length does not exceed 655 feet.
•
If the cable length is greater than 133 feet, a PC running HyperTerminal
and an RS-232 cable must be used to provision the cable length. Refer to
Section 5 of this practice.
•
Verify that the DS1 equipment at the far end of the DS1 cable is operating
properly.
•
If the DS1 indicator remains red, the O3-4D1L3 module is defective and
should be replaced.
