Mitel Harnais système 50 ports

In a busy enterprise telephony room, a technician is connecting a new 50-port station card in a Mitel 3300 ICP to the building's main distribution frame. With the Mitel 50 Port System Harness, the job is straightforward: plug the 50-pin Amphenol connector into the card, then terminate the 25 twisted pairs on a punch-down block. This harness is built for exactly that scenario, providing a reliable, organized link between your Mitel PBX and the rest of your voice infrastructure.
