Nortel 25URP00733EAF: Nortel transmission plug-in unit recorded as a 140 Mbit/s OISU. The abbreviation is unexpanded and the host shelf is unconfirmed.

The Nortel 25URP00733EAF is designated a 140 Mbit/s OISU on our supplier record. 140 Mbit/s places it at the top level of the European plesiochronous hierarchy, but we have not expanded the OISU abbreviation, because more than one reading is plausible and we would rather not publish the wrong one. That designation is what our supplier record gives, and we have not expanded it beyond what we can support, so treat the wider detail as unconfirmed until we have checked the unit.

Transmission plug-in units like this one were built for a specific subrack and a specific software load, so the host system matters more than the abbreviation on the front panel. We would rather check the unit than assume which shelf it came out of.

Let us know which Nortel system this is destined for and we will verify the item in stock against it before proceeding. Tech-Star (UK-based, shipped worldwide) holds Nortel equipment for maintenance and expansion projects. Please contact our sales team for availability, condition and pricing.
