TruePulse is looking to purchase NT7E05BG and NT7E05BH for the Nortel S/DMS TransportNode OC-3/OC-12 system.  It is possible that you may be familiar with these as Ciena NT7E05BG and Ciena NT7E05BH.

The OC-12 VTM circuit pack is used in the VTM ring ADM. In a VTM ring, the primary transport interface circuit packs in each ring ADM are OC-12 VTM circuit packs, which support VT bandwidth management (VTM).  For this application, two units are required. One unit handles the working and protection channels traveling in the east-to-west direction, and the other unit handles the working and protection channels traveling in the west-to-east direction.

The OC-12 VTM circuit pack provides

•interface to the OC-12 signal

•bandwidth management at the STS-1 level and at the VT1.5 level

•timing to maintain the synchronization of the network element

Interface To The OC-12 Signal

The OC-12 VTM circuit pack generates an OC-12 signal from STS-1 electrical signals. The optical signal is a 1310-nm (intermediate reach) wavelength. Each circuit pack processes a maximum of 12 STS-1 transmit and receive signals independently. The STS-1 signals are exchanged with tributary circuit packs by way of the backplane add and drop buses.

TruePulse is currently looking to purchase:

NT7E05BF, HECI code SNI2AAD1AA or NTI3XESGAA, is an OC-12 IR 1310nm VTM Optical Interface Circuit Pack (FC)

NT7E05BG, HECI code SNI2BAD1AA or SNI3X9SGAA, is an OC-12 IR 1310nm VTM Optical Interface Circuit Pack (ST)

NT7E05BH, HECI code SNI2CAD1AA or SNI3Y5SGAA, is an OC-12 IR 1310nm VTM Optical Interface Circuit Pack (SC)

TruePulse buys and sells decommissioned Nortel optical modules.  In addition to the S/DMS TransportNode OC-3/OC-12 platform, we are also looking to purchase other Nortel optical platforms including the S/DMS TransportNode OC-48, Optera Metro 5100 and Optera Metro 5200, and the Optera 3500.
