- Coexists with OS 4000 SoftGate/Branch on the same system.
Typical applications
Hotel room phones — 24 UP0/E per shelf for 24 rooms; ICCS-compliant cabling for 1000 m reach.
Hospital ward — digital exam-room phones in non-IP buildings.
Bank branch — migration of legacy Optipoint/OptiSet infrastructure to the V11 platform.
Manufacturing site — line infrastructure for noise-resistant digital phones in the field.
Legacy SLMO refresh — prerequisite for V7 R2+ platform upgrade.
