Nortel QPC775F (OPTera Metro / PDH-SDH / Passport-MSS / networking portfolio) Telecom System Card / Module Image 1

Nortel QPC775F: Clock circuit pack from Nortel’s SL-1/DMS-1 generation, supplying the switch’s master timing reference.

The Nortel QPC775F is a Clock circuit pack from Nortel’s earlier SL-1/DMS-1 generation of central-office and PBX switching hardware, supplying the master timing reference that keeps a switch’s digital circuits synchronised.

Older Nortel SL-1/DMS-1-era switching equipment remains in service at some legacy sites, and genuine spares such as this one are sought to keep an existing installation running rather than face a full platform replacement. The QPC-prefixed card range predates Nortel’s later DMS-100/Meridian 1 numbering and is not interchangeable with it.
