NTN442AB and NTN442AJ

TruePulse is actively seeking Nortel Optera 3500 OC-48 boards NTN442AB and NTN442AJ.   They may also be known as the Ciena OM3500 NTN442AB and NTN442AJ.

The NTN442 series are OC-48 DWDM interface cards for the OM3500 are each specific to a certain wavelength. TruePulse is actively searching for:

• NTN442AB, HECI code SOCPAAB/ SOCPAABAAA, is an OM3500 OC-48/STM-16 LR DWDM circuit pack, Band 1 Channel 2.
• NTN442AJ, HECI code SOCPADN / SOCPADNAAH, is an OM3500 OC-48/STM-16 LR DWDM Shielded circuit pack, Band 1 Channel 1.

But we would actually consider purchasing most of the OM3500 OC-48 wavelengths, including, but not limited to: NTN442AC, NTN442DA, NTN442EB, NTN442FC, NTN442AK, NTN442AL, NTN442AM, NTN442EA.

On the physical layer (layer 1), an Optera Metro 3500 network can be configured as a unidirectional path-switched ring/subnetwork connection protection (UPSR/SNCP), a 1+1 linear/MSP configuration, a 2-fiber bidirectional line-switched ring/multiplex section-shared protection ring (BLSR/MS-SPRing), or as an unprotected fiber optic run.

On the data link layer (layer 2), an Optera Metro 3500 network can be configured as an Optical Packet Edge ring with layer 2 protection, in accordance with Resilient Packet Rings (RPR) defined by the IEEE 802.17 working group.

TruePulse is looking for other Nortel OM3500 cards too.  But we are searching for equipment from other Nortel platforms including the OM 6500, Optera Connect DX, the OME 6000, and the S/DMS TransportNode OC-48 NE.  If you prefer, we could sell your equipement on consignment.
