!
CAUTION:
DDM-2000 circuit packs contain static sensitive components
which can be damaged by electrostatic discharge. A static
ground wrist strap must be worn when handling the circuit
packs. See electrostatic discharge considerations in Trouble
Clearing: TAD-100
.
NOTE:
The end-to-end network must be established before
continuing with this procedure. If all the nodes of the network
have not been equipped and installed, refer to System
Turnup/Circuit Order: IXL-001 for procedures to equip the
DDM-2000 shelves, and to establish the end-to-end network.
NOTE:
This procedure assumes that STS1E circuit packs, optioned
for low speed, have been installed during the initial shelf
turnup at the EC-1 terminating end(s) of the circuit. The
other terminating end(s) may be equipped with DS3, STS1E,
or MXRVO and DS1/DS1PM circuit packs. If the appropriate
circuit packs have not been installed and the system is in
service on other groups, refer to System Turnup/Circuit
Order: IXL-001 for procedures to equip the new groups.
NOTE:
If the DDM-2000 fails to respond in the indicated manner,
refer to Trouble Clearing: IXL-001.
At the EC-1 terminating (drop) node(s), determine which STS1E
circuit pack is to be put into service and what options are to be
selected.
