TruePulse is looking to purchase NTWR30BA and NTWR30CA for the Nortel Optera Connect DX system.  You may also know them as the Ciena NTWR30BA or the Ciena NTWR30CA.

The NTWR30BA, HECI code WMTUCSA, is a dual OC-48 intermediate reach Transmitter/Receiver.  It is a non-DWDM module.

The NTWR30CA, HECI code WMTMP02, is a dual OC-48 long reach Transitter/Receiver.  It is a non-DWDM module.

Both the NTWR30BA and NTWR30CA are Dual OC-48 T/R full-height circuit pack that support two OC-48 facilities for a maximum capacity of 5.0 Gbit/s.

The following three circuits support the Dual OC-48 LR T/R interface:

• the transport control subsystem (TCS)

• the point-of-use power supply (PUPS)

• the electro-optics controller (EOC)

The TCS controls the operation of the Dual OC-48 LR T/R interface. The TCS provides communication between the shelf controller and the Dual OC-48 LR T/R interface. The TCS also generates alarms and activates the LEDs on the circuit pack faceplate.

The PUPS generates all the voltages required by the Dual OC-48 LR T/Rinterface.

The electro-optics controller controls the receive and transmit optical channels. The EOC also provides the TCS with status information about the optical control loops and alarms.

TruePulse buys and sells most types of surplus and refurbished Central Office Telecommunication equipment.  Besides the NTWR30BA and NTWR30CA, we are interested in other Nortel Optera Connect DX modules as well.  In addition, we need Nortel S/DMS TransportNode OC-3/OC-12 cards and Nortel Optera 3500 equipment.  Please let us know what you have available for sale.
