Family: [OpenScape 4000 Cards](https://www.promark.tr/en/products/openscape-4000-cards)

8-port analog trunk board for OpenScape 4000 — successor to TM2LP and TMC16. Supports HKZ Loop Start (worldwide) and country protocols such as DID Italy. Same layout/dimensions as the HiPath 3800 board, only the part number and LW differ.

## Key features

- 8 analog trunk ports — central-office (CO) line connections.
- Replaces TM2LP and TMC16 (legacy OS 4000 analog trunk cards).
- HKZ (Loop Start) — global Loop Start protocol previously on TM2LP.
- DID Italy — Direct Inward Dial protocol for Italy.
- Extendable via the PTIMES (Public Telephone Interface Module Extension) module — §6.10.6.
- Shared design with HiPath 3800 — same layout and dimensions, only part number and LW differ for OS 4000.
- Pin assignment documented in datasheet §6.10.4.
- Lightning protection — §2.3 reference, external-line resilience.
