∗ 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.

‡‡ 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.
