Equipping rules
The NPx must be installed in slot 16. See Table 3-3 on page 3-6 for operational
temperature ranges.
Alarm LED definitions
The following table provides a list of LEDs on the NPx circuit pack.
ILAN interface
(NTN425AA)
The ILAN circuit pack (NTN425AA) provides the Ethernet hubbing
functionality required to interconnect OPTera Metro 3000 shelves. The ILAN
circuit pack provides a low cost solution to Ethernet connectivity between
OPTera Metro, OC-48 Classic Phoenix SP, OPTera Connect DX and OPTera
Long Haul OPCs and the OPTera Connect HDX as well as the capability to
daisy-chain up to 16 shelves. The ILAN interface gives the user access to
ILAN ports 1 and 2 on the LOAM.
Note: The ILAN interface circuit pack does not give the user access to
COLAN ports.
Equipping rules
The ILAN circuit pack must be inserted in slot 16. See Table 3-3 on page 3-6
for operational temperature ranges.
OC-192 optical interface circuit pack
(NTN445CB, DA)
The main transport OC-192 circuit pack operates at an OC-192 line rate (9.953
Gbit/s for IR and 10.709 Gbit/s for LR and DWDM). The OC-192 circuit pack
can be installed in slots 11 and 12 in a UPSR, 1+1 linear system and BLSR. In
the 1+1 linear protection scheme, OC-192 circuit packs can be provisioned in
either unidirectional or bidirectional mode. See
Table 3-3 on page 3-6 for
operational temperature ranges.
See Table 3-9 for the OC-192 optical wavelengths and line rates supported for
the transmit and receive optical circuit packs.
