Mitel 9109-060-000-SA SX-200 / SX-2000 / 3300 ICP telephone system PBX Card / Module

The Mitel 9109-060-000-SA is a T1 Clock Module running at Stratum 3 accuracy, providing timing synchronisation for T1 digital trunk interfaces on the SX-200 ML/EL controller. Stratum 3 clocking is the standard accuracy grade used where the system needs to hold its own reasonably precise timing reference rather than relying solely on an upstream carrier clock, which matters for keeping multiple T1 spans and connected equipment in sync. Losing clock accuracy on a T1 span shows up as slips and audible clicks on calls, so the clock module is a common maintenance replacement on older T1-fed systems. It is a genuine Mitel part for the SX-200/SX-2000/3300 ICP telephone system range. Tech-Star (UK-based, shipped worldwide) supplies Mitel spares for engineers maintaining or expanding SX-200/SX-2000/3300 ICP installations.
