URL: https://www.promark.tr/en/products/openscape-4000-egw
Category: PBX & UC
Family: [OpenScape 4000](https://www.promark.tr/en/products/openscape-4000)

Branch gateway built on OpenScape 4000 hardware and software — successor of AP 3700-9 shelves with HG3575. The whole IP Distributed Architecture (IPDA) feature content is available. For large branches heavy in analog/TDM/DECT and trunk needs — the option where EcoBranch is not enough. From V10R1, one EcoServer supports two LTU shelves (XEGW); an integrated SoftGate (iSG) can run on the EGW.

## Key features

- Full IPDA (IP Distributed Architecture) feature content.
- Shelf types: AP3700-9 and AP3700-13 (mixable).
- V10R1+: second LTU shelf on one EcoServer (XEGW) — more AP shelves per location; AP3300 not supported for the second shelf.
- Integrated SoftGate (iSG) can run on the EGW from V8R2.
- Survivable unit optional — typical deployment 'Survivable Enterprise GW' hosted on the EGW.
- Position among the 3 branch types: EcoBranch (small-mid) · Survivable SoftGate (pure software) · Enterprise Gateway (heavy legacy / large branch).
- Promark: branch type selection, shelf/card configuration, IPDA design and commissioning.
