Huawei USIA7 (CN21USIA7, 03052589) General Service Interface Unit board for Huawei core network platforms.

The Huawei USIA7 (also marked as CN21USIA7, material code 03052589) is a General/Universal Service Interface Unit board used within Huawei core network platforms. It provides interface and service processing functions supporting voice-over-broadband (VoBB), PSTN interconnect, and convergent conferencing solutions on Huawei’s softswitch-era core network systems.

As a service interface board rather than a subscriber access or transmission line card, the USIA7 sits within the core network equipment shelf and handles interface signalling and service processing tasks for the platform it is fitted to. It is a spares and capacity item for operators maintaining legacy Huawei core network deployments still carrying VoBB and PSTN traffic.
