Key features
- DIUT 3rd gen — unifies DIUN2 (Q2196) and DIU2U (Q2216) technology on a single PCB; DIUT3 brings the V11 refinement.
- Two LW variants: E1 (ISDN PRI / CAS) or T1 (BOS / MOS / CVN) — region-specific configuration.
- Access to the LTU shelf's 4 standard PCM highways.
- Support for the 4 additional highways of the extended (Wideband) LTU shelf.
- Optical backplane interface NOT supported (per §6.1.1 doc note).
- Configured via the AMO BCSU command (§6.1.5).
- LED indication: power, sync, trunk level, fault.
- Hot-pluggable: removal/replacement in §6.1.6/6.1.7.
Typical applications
European ISDN PRI termination — 30-channel PRI on E1 LW.
North American T1 — 24-channel BOS / MOS / CVN on T1 LW.
DIUT2 refresh — V11 migration via DIUT3 for redundancy and capacity.
Multi-country trunk config — same PCB, two LW variants for regional adaptation.
Protect existing PRI investment — phased migration to IP, DIUT3 extends lifecycle.
