Product Overview

eSpace U2990 is built on the mTCA architecture and serves as the core switching device for the UC solution. A single chassis supports up to 30,000 users, with a maximum of 7 cascaded chassis supporting up to 300,000 user connections.

A single frame supports 128 E1/T1 trunks and integrates E1/ISUP, E1/TUP, E1/PRI, and T1/PRI with SIP, enabling unified narrowband/wideband access for both traditional PBX and PSTN interconnection. Dual-group clustering provides cross-site disaster recovery.

Key Features

  • Based on the mTCA architecture, a single system 7 can cascade up to 300,000 user connections.
