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 3-6for 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 3-6for operational temperature ranges.

See Table 3-9for the OC-192 optical wavelengths and line rates supported for the transmit and receive optical circuit packs.
