The Mitel 50005103 is a 16-Port ONS Line Card. It is used with an Analogue Service Unit II (ASU II, part number 50005105) and provides sixteen On-Premise Station (ONS) circuits for analogue extensions. Each ONS port requires a licence (part number 54002701), and a minimum software release of 3300 R7.0 UR2 is required. It is part of Mitel’s SX-200/SX-2000/3300 ICP PBX platform, a digital and IP telephony family still supporting many enterprise and SME sites in service today. Sites running the 3300 platform commonly hold a spare ONS line card of this kind to expand analogue extension capacity or swap out a faulty card without downtime. This is genuine refurbished Mitel stock, supplied with a warranty by Tech-Star (UK-based, shipped worldwide).
