OPTera Packet Edge System 4x100BT circuit pack (NTN433BB)

Each OPTera Packet Edge System circuit pack works as a distributed switch and bridge to connect Ethernet LANs on a high-speed SONET network.

Equipping rules

Each OPTera Packet Edge System 4x100BT circuit pack requires an 8xRJ-45 Front I/O module (NTN452NA) on the OPTera Metro 3500 Shelf (NTN476AA, NTN476DA). On the OPTera Metro 3500 Universal Shelf (NTN476AH) you must use the 8xRJ-45 Front Enhanced I/O module

(NTN452NH) or the 8xRJ-45 Rear I/O module (NTN452HB).

Both versions of the shelf support eight OPTera Packet Edge System 4x100BT circuit packs in slots 3 through 10. 4x100BT circuit packs only operate in an unprotected mode.

If a 2x100BT-P2P, 4x100FX, 4x100BT or 2xGigE/FC-P2P circuit pack is inserted into an odd slot (nodd), then you can only insert one of the following circuit packs into the even slot (nodd+1):

•2x100BT-P2P

•4x100BT

•4x100FX

•2xGigE/FC-P2P

If a 2x100BT-P2P, 4x100FX, 4x100BT or 2xGigE/FC-P2P circuit pack is

inserted into an even slot (neven), then you can only insert one of the following circuit packs into the odd slot (neven-1):

•2x100BT-P2P

•4x100BT

•4x100FX

•2xGigE/FC-P2P

Note: There is no equipment protection for the 4x100BT circuit pack.

See Table 3-3 on page 3-6for operational temperature ranges.

Note 1: If there is a 1-28 DS1 I/O module installed, and if slots 5 and 6 are not equipped with DS1 mappers, you may not install 4x100BT circuit packs in slots 5 or 6 (there is not enough room for slot 5 or slot 6’s 8xRJ-45 I/O modules).

Note 2: If there is a 29-56 DS1 I/O module installed, and if slots 7 and 8 are not equipped with DS1 mappers, you may not install 4x100BT circuit packs in slots 7 and 8 (there is not enough room for slot 7 or slot 8’s 8xRJ-45 I/O modules).
