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:
This procedure assumes that the DDM-2000 is in service
and that a new HDSL port or HDSL circuit pack is being
added to a group that is already in service and equipped with
MXRVO circuit packs at the DS1 terminating end(s). It also
assumes that STS1E circuit packs have been installed if the
other end is an EC-1 interface. If proper 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 add a new group (MXRVO or STS1E).
NOTE:
A maximum of three BBF8 HDSL circuit packs, including a
protection circuit pack, can be installed in any one function
group. Both service and protection MXRVO circuit packs
must also be installed.
NOTE:
If the DDM-2000 fails to respond in the indicated manner,
refer to Trouble Clearing: IXL-001.
Determine which HDSL ports/slots are to be put into service and
what options are to be selected.
2. Verify that no LEDs or alarms are activated. If any LEDs or alarms
are activated, refer to Trouble Clearing: IXL-001 and follow the
appropriate trouble-clearing procedure.
