177A Retainer card must be installed in unused slots of a partially equipped muldem. Not required with BBF5.
† The 22-type OLIUs must be present in main-1 and main-2 for proper ring operation. If signal degrade protection is not used,
the 22F/22F-U and 22G-U/22G2-U OLIUs can be mixed in the same shelf. The 22F2-U provides signal degrade protection
switching and can be mixed with 22G-U/22G2-U OLIUs. The BBF2B TGS is recommended for rings to minimize protection
switching times in case of a manual circuit pack removal.
‡ The BBF2B circuit pack optionally provides DS1 timing outputs. It is recommended for rings to minimize protection switching
times in case of a manual circuit pack removal.
§ Signal degrade protection switching requires 22D-U or 22G-U/22G2-U or 22F2-U OLIUs.
¶ The BBF3 is the DS1PM circuit pack which can be used in place of or mixed with the BBF1/1B. If mixed within a low-speed
group the protection circuit pack must be a BBF3. If the DS1PM feature is "enabled" using the
set-feat
command, the BBF3
has additional performance monitoring capabilities. The BBF3B can perform individual DS1 loopbacks using R13 or later.

Required in Group 1 and Group 3 shelves functioning as DDM-2000 FiberReach hosts with 27G-U/27G2-U OLIUs.
†† When 24G-Us are used in a G3 shelf (the 24G-Us must be deployed in pairs), the front cover must be modified using the G3
to G4 Front Cover Modification Kit. The 24G-Us also require an Interconnect Cable Assembly 847721271.
‡‡ 26G2-U requires OC-3 Group 4 Shelf.
§§ Up to three BBF8s can be installed per low-speed group. Future enhancements may support higher density.
¶¶ The 27G2-U is required for some enhanced FiberReach host topologies with Release 13.0. When the 27G-U/27G2-U is used
in a G3 shelf, the front cover must be modified using the G3 to G4 Front Cover Modification Kit.

BBG4B DS3 required to support enhanced DS3 performance monitoring.
††† The BBG6(ls) is the BBG6 circuit pack with its switch set for low-speed.
