Powering, Verification, and Circuit Pack Installation
Table 4-1. Release 13 Circuit Pack Compatibility (Sheet 1 of 2)
177A Retainer card must be installed in unused slots of a partially equipped function group.
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/22G3-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/22G3-U OLIUs. The BBF2B TGS is recom-
mended 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, 22G-U/22G2-U/22G3-U or 22F2-U
OLIUs.
¶
The BBF3 is the DS1PM circuit pack which can be used in place of or mixed with the BBF1/
BBF1B. 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 single home Fiber-
Reach hosts with 27G-U/27G2-U OLIUs.
