TruePulse would like to acquire NT8E11MM and NT8E11KL for the Nortel S/DMS TransportNode OC-48 NE.  This system is alternately called the FDN2400, or the Classic OC-48.  You may possibly know these modules as the Ciena NT8E11MM and Ciena NT8E11KL.

The NT8E11MM, HECI code SNT5J8G, is an OC-48 DWDM 1552.52nm 1:N transmit interface module

The N8E11KL, HECI code SNT5JYG, is an OC-48 DWDM 1533.47nm 1:N transmit interface module

The Nortel S/DMS TransportNode OC-48 network element operates with a maximum of 48 STS-1 signals (or equivalent) for each OC-48 optical channel. You can equip the OC-48 terminal shelf with a mix of DS3, STS-1, OC-3, STM-1J, STS-12, OC-12, and the Nortel Networks OPTera Packet Edge System (2x1000SX, formerly iPT1000) tributaries. The STM-1J and Packet Edge tributaries are only supported on GR-1230 Rings.

With double-width OC-3 interface circuit packs, three STS-1 timeslots are available per quadrant in a protected configuration or six STS-1 timeslots in an unprotected configuration. An OC-48 network element equipped with four protected double-width OC-3 interfaces supports a maximum of 12 add-drop STS-1 connections. An OC-48 network element equipped with eight unprotected double-width OC-3 interfaces supports a maximum of 24 add-drop STS-1 connections.

The maximum number of bidirectional working channels for a fully equipped multishelf 1:N system is 11.

In addition to the NT8E11MM and NT8E11KL, TruePulse would like to acquire many other modules for the Nortel S/DMS TransportNode OC-48 NE.  We are also interested in modules from other Nortel platforms, including the CS2000, the DMS-100 and OME 6500. 

Please send us an email to let us know about surplus Central Office telecom equipment that you have available.
