Nortel 25UMU00722EHQ: Nortel transmission unit recorded as 2 to 8 Mbit/s, working between the first and second PDH levels. Host shelf unconfirmed.

The Nortel 25UMU00722EHQ is recorded as a 2 to 8 Mbit/s unit. Those are the first and second levels of the European plesiochronous hierarchy, so the card handles muldex or interface work between 2 Mbit/s tributaries and an 8 Mbit/s aggregate. The shelf it belongs to is not stated on our record. 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.

Nortel’s transmission range covered optical line terminals, plesiochronous and synchronous multiplexers and the analogue line plant that fed them. Part numbers in this style identify plug-in units rather than complete systems, and the same abbreviation can appear on units built for more than one subrack, which is why we prefer to confirm the platform physically.

If you can tell us the system this is going into, or send a photograph of the board label, we will check the unit we hold against your requirement before you order. Tech-Star (UK-based, shipped worldwide) supplies tested Nortel hardware on a quote-only basis. Contact our sales team for current availability, condition and pricing.
