Send it to the MMR or directly to customer’s own facilities.

Cross – connection
A cross-connect is a physical, point-to-point cable that establishes a direct and exclusive connection between two distinct customer-specified endpoints. These cross-connects enable businesses to establish dedicated and private connectivity with one another, inside a carrier house space, in order to exchange data traffic.
Barcelona CLS provides fibre interconnection between parties and fibre extensions via MMR cross-connect.
Barcelona CLS guarantees the installation of all cross-connects within the agreed-upon SLA, as specified by our customers.

The Barcelona CLS GPS service delivers ultra-accurate time synchronization through multi-constellation GNSS (GPS, GLONASS, BeiDou, Galileo, QZSS), using high-precision GNSS receivers and rubidium atomic clocks for resilience and reliability—even during signal interruptions.
Supported Protocols
- NTP (v3 & v4): Millisecond-level accuracy for scalable network environments.
- PTP (IEEE 1588-2008): Sub-microsecond precision for critical applications like telecom, finance, and measurement systems, requiring compatible hardware and network infrastructure.
Key Benefits
- Robust, redundant GNSS-based time distribution
