Any chance that you have a decommissioned Hekimian 3512-08FP available? It is a 3219A/3500 Shelf Controller. The HECI code is SMPQCBG, with an alternate part number 6700-1652-02.
In 2000, Spirent Communications purchased Hekimian Labs. So you may well have a Spirent-branded 3512-08FP.
In addition to the 3512-08FP, we are interested in other Hekimian/Spirent modules that you have available. We are also interested in circuit boards from other manufacturers such as Calix, Tollgrade, Omnitron and DragonWave. Please let us know about any surplus or decommissioned Central Office telecommunication equipment that you may have.
