The Marconi MSH‑11CP is an enhanced variant of the MSH‑11C access node, purpose-built for multiservice SDH transport in legacy telecommunications networks. It supports STM‑1 on both tributary and optical sides, along with up to 63 E1 interfaces for voice, data, and PDH aggregation. Designed for high‑density compact installations, the MSH‑11CP combines flexible tributary mapping, carrier-grade reliability, and integrated cross‑connect functionality into a compact chassis suitable for last‑mile access, metro aggregation, and enterprise leased‑line delivery.
The MSH‑11CP’s advanced configuration options include fast‑Ethernet card support for efficient mapping and grooming of Ethernet traffic over SDH (VC groups, GFP, LCAS), enabling operators to carry modern packet services reliably over legacy infrastructure. Carritech supports customers operating the Marconi MSH‑11CP by sourcing full units, spare modules, line cards, and power components through our global network. We ensure each item is quality‑tested, verified for compatibility, and delivered with transparent logistical and lifecycle support.
Enhanced STM‑1 Capacity: Dual STM‑1 transport interfaces optimize aggregation and distribution in access networks.
Full E1 Tributary Support: Configurable support for up to 63 E1 ports, suitable for voice, data, or PDH services.
Modular Fast‑Ethernet Functionality: Supports mapping Ethernet traffic into VC‑12 or VC‑4 containers, with virtual concatenation and LCAS support for flexible capacity scaling.
SDH Cross‑Connect & Protection: VC‑12 and VC‑4 level switching, with support for protection schemes like SNCP and MSP.
Service Grooming & Transport Optimization: Efficient traffic aggregation with pointer processing, grooming, and traffic protection.
Carrier‑Grade Design: High MTBF, low power usage, and resilient performance in operational environments.

| Time Period | Brand / Company | Role / Notes |
|---|---|---|
| Early 2000s – 2006 | Marconi Communications / Marconi Corporation plc | Original designer and marketer of the MSH‑11CP, positioned as a high‑capacity SDH access node within its PacketSpan portfolio. |
| 2006 – Present | Ericsson (legacy support only) | After acquiring Marconi’s telecom assets, Ericsson gradually phased out sales and formal support for the MSH‑11CP, offering limited support to legacy users under service agreements. |
| Present (Secondary Market) | Independent Resellers & Support Specialists (e.g., Carritech) | Carritech sources and supplies Marconi MSH‑11CP systems, modules, and accessories; offering testing, logistics support, and lifecycle extension services to maintain legacy SDH deployments. |
