Avaya 700184807 IP400 Digital Station Module 16pt

Avaya IP400 Digital Station Module DS16, part number 700184807, is an external expansion module for Avaya IP Office IP400 systems that adds 16 digital station ports for DS-based telephones. It plugs into the IP400 expansion bus to provide sixteen dedicated digital channels, allowing mid-size IP Office installations to scale beyond the base DS capacity. As part of the IP400 Digital Station family, the DS16 complements other expansion options such as the 30-port DS30, giving integrators a choice to match deployment needs. The module is designed to support additional digital handsets used with IP Office, enabling more lines and extensions without swapping the core system. In installation literature, this item is identified specifically as IP400 DS16 with code 700184807, making it the standard route to extend digital-station capacity on an IP Office IP400 platform. Typical deployment scenarios include office environments that already rely on Avaya digital desk sets alongside IP phones, where adding 16 more DS ports can accommodate growing teams or reconfigured workflows. The DS16 itself is one of the IP400 external expansion options documented for the platform, and it is commonly listed by Avaya under the IP Office platform compatibility landscape as the 16-port digital station module associated with the 700184807 part code.
