The Cisco IP DECT DBS-110 Single-Cell Base Station allows up to 30 SIP registrations per unit and up to 2 base stations and 12 repeaters per system. At its maximum size a DBS-110 system supports 20 concurrent narrowband or 10 concurrent wideband calls. The Cisco IP DECT DBS-210 Multi-Cell Base Station may be installed as a single cell solution that can grow up to a large system with 254 integrated base stations that supports up to 1000 SIP registrations and 2000 calls. The Cisco IP DECT RPT-110 Repeater extends the connectivity range of handsets registered to the Base Stations. Each Base Station and Repeater has a signal radius of 50 meters (164 feet). The Deployment Guide provides more detail on how combinations of Base Stations and Repeaters may be installed to satisfy different signalling coverage scenarios.
