1.2 Understanding The DXP Plus
Station and line
capacity
The DXP Plus system is a 480-port, three-cabinet, digital communications system
consisting of one main cabinet and two expansion cabinets. With analog,
loop-start, DID, or multipurpose line boards, the maximum configuration is 0
lines and 480 stations, or 232 lines and 8 stations. By using the digital carrier
transmission option (E1 or T1), however, you can enhance the system’s capacity
to a maximum of 560 ports, with a 240 line and 320 station maximum
configuration.
How the system
works
The Comdial DXP Plus digital communications system provides cost-effective
voice and data communications using the latest PCM-TDM (pulse code
modulated/time division multiplexing) digital switching technology. The DXP
Plus switching architecture provides a non-blocking switching array that gives all
ports simultaneous access through the system. The digital technology allows
simultaneous voice and data transmission using 2B+D signaling (CCITT
specification for basic access data transfer rate for ISDN on a single twisted pair)
when data terminals become available. The design is a fully modular, ISDN
(integrated services digital communications network) system with 1024 usable
time slots and the flexibility for upgrade and expansion as needed. The DXP Plus
digital communications system supports the current Comdial line of DigiTech,
Impact, and ExecuTech telephones.
