!
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

!
CAUTION:
In addition to primary lightning protection, an external
Lightning and Surge Secondary Protection Assembly
(ED-8C783-30 or equivalent) is required for HDSL circuits
used in outside plant applications.
NOTE:
The OC-3 system 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 establish the system.
NOTE:
If the DS1 terminating end(s) are in a DDM-2000 OC-3, this
procedure assumes that MXRVO circuit packs have already
been installed during initial shelf turnup and either MXRVO
or STS1E circuit packs have been installed during initial shelf
turnup at the other DDM-2000 OC-3 terminating end(s) of
the circuit. If the terminating end is in another system, it is
assumed that the appropriate installation and connections
have been made to that system. If the appropriate circuit
packs have not been installed and the system is in service
on other groups, refer to DLP-506 for procedures to install
new MXRVO circuit packs and DLP-564 for procedures to
install new HDSL circuit packs.
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.
