Mitel MC320BB SX-2000 ONS analogue line card.

The Mitel MC320BB is an ONS (on-premise station) line card in the MC320 series for the Mitel SX-2000 PBX platform, providing analogue extension circuits within the switch’s peripheral cabinets.

The MC320 family, which includes confirmed sibling variants such as the MC320BA and MC320BE, delivered 16 analogue extension circuits per card and formed the standard analogue line interface for SX-2000 deployments throughout the platform’s service life.

This card is sourced to maintain or expand analogue extension capacity on an existing SX-2000 system. Tech-Star (UK-based, shipped worldwide) checks every card before it ships. Get in touch to confirm compatibility with your SX-2000 platform.
