Establish Initial End-to-End T1 Service
(Group Equipped But Not In Service)
DO ITEMS BELOW IN ORDER LISTED. . . . . FOR DETAILS, GO TO
1. !
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 .
!
CAUTION:
In addition to primary lightning protection an external
Lightning and Surge Secondary Protection Assembly
(ED-8C783-30 or equivalent) is required for T1 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:
The BBF6 T1EXT circuit pack can be used only with the
BBG2B MXRVO circuit pack in the Group 4 shelf.
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 MXRVO 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 System Turnup/Circuit Order: IXL-001 for procedures to
add a new group for T1 service.
