Key features
- Subscriber Trunk Module IP eXtended (STMIX) — serves as OpenScape 4000's HG 3500 Common Gateway.
- Two 1 Gbps Ethernet network connections — redundant IP backbone or separate VLANs for QoS isolation.
- 120 channels with the PDMX (PMC DSP Module Extended) module — sufficient capacity per card for heavy traffic.
- x86 CPU-based voice encoding — software-driven, flexible codec management.
- Hot-pluggable — can be inserted/removed while the system runs, no outage at commissioning.
- Installs in a standard peripheral slot of the AP3700 host shelf — works via backplane with the default peripheral board.
- USB type-B service interface — local access for diagnostics and tests.
- Active/standby HG 3500 configuration supported (from V8R1) — high-availability trunk connectivity.
- Successor of the STMI2 card — mandatory upgrade for installations where STMI2 support ended at V10R0.
Typical applications
Migrate TDM operator lines to SIP trunk — phased migration, continuous operation, 120 channels per card.
Add IP trunk capacity to an existing OpenScape 4000 — preserves AP3700 shelf occupancy.
Standby HG 3500 configuration — two STMIX cards for high-availability operator connectivity.
STMI2 → STMIX hardware refresh — mandatory on V10R0+ systems where STMI2 support has ended.
