The Nortel NTAK20BD is a Stratum 4 Clock Controller Daughterboard for the Meridian 1 Option 11 platform. It provides Stratum 4 timing reference and clock-control functions for an Option 11 system, keeping the system’s digital trunk and line timing synchronised to network standards where an external Stratum 4 reference is required. Option 11 systems of this generation remain in service in a number of established small-to-mid-size business telephony installations, and genuine clock-controller daughterboard spares are a routine requirement for maintaining correct network timing or restoring redundancy after a card failure. Tech-Star (UK-based, shipped worldwide) stocks Nortel Option 11 cards to support ongoing system maintenance. Please contact our sales team to confirm exact compatibility and for current stock and pricing.
