resistance of the available copper telecommunication facilities, as shown in the
following table.
For -48Vdc operation, you connect one pair of 19 AWG wires in the stub end of the
power cable to a local -48Vdc power source. This cable terminates on a Tyco
connector in the Compact Remote enclosure. A jumper cable connects between the
Tyco connector and the power terminals on the -48Vdc power supply.
All Stinger CR ATM DSLAM status lights momentarily turn ON just after startup,
except as noted below for the COP, IP2000, and control modules.
Status lights
The status lights on the modules in the Stinger CR ATM DSLAM unit indicate the
operating status of each module.
Note
For information about status lights on the OLIM in the host Stinger unit, see
“Interpreting OLIM status lights” on page B-2.
IP2000 and control module status lights
All IP2000 and control module status lights, except the MASTER light, momentarily
turn ON just after startup, and all six TRUNK STATUS lights turn OFF. After the
system starts up, each light indicates status information as described in Figure 3-4.
Figure 3-32 shows the locations of the status lights on an IP2000. The locations on a
control module are similar, except that the control module does not have a gigabit
Ethernet interface and its associated lights.
