Pbx Hybrid Networks

PBX and Key/Hybrid Systems PBX and Key systems are the wave of communication for business everywhere. The key difference between PBX and Key/Hybrid systems are the amount of stations each can handle. Key systems are designed for clients with very small line size requirements and very basic needs. It usually handles between 16 to 48 stations. PBX systems on the other hand handle a lot more stations as well as more features and sophistication. PBX are designed for larger corporations and cost much more than a simple key system communication need. Another key advantage of PBX system is it allows for room for corporation growth over the years than that of a Key System or Hybrid system. An example of a PBX system and some of its features is the Fujitsu BCS Series 3:1 Model Series 3 Product Type Digital PBX FCC Registration Numbers (Key) BJ885Z-60084-KF-E; (Hybrid) BJ8USA-60083-MF-E (PBX) BJ8USA-75355-PF-E Date Announced July 1993 Number of Systems Installed Approximately 2,375 + Line Capacity 480 Port Capacity 588 Trunk Capacity 4 to 240 (dependent on # of lines configured) Simultaneous Calls Possible 294 Traffic Capacity (BHCAs) 10,000 Switching Matrix TDM Main System CPU Fujitsu proprietary 8-bit or 16-bit CPU H5H5 Component Redundancy Not available Amt. of Main System Memory 1.5MB ISDN Support PRI only (BRI not available) T-Carrier Support Direct T1 interface Wireless Support SpectraLink WTS Voice Messaging Support Fujitsu TranSend/TranSend Lite unified messaging platform; Fujitsu's IVS voice messaging platform; or various third-party voice mail solutions.

The price rang of the phones of each line are between 300 and 500 dollars per line with a basic package of 6500 for the TransSend unified messaging platform. An example of a functioning Key/Hybrid System is the Lucent Merlin Legend. A couple features of this key system are:2 Digital key/hybrid/PBX/behind-Centrex system H2H2 Date Announced August 1991 Date Installed October 1991 FCC Registration Numbers Key--AS593M-72914-KF-E; multifunction hybrid--AS593M-72682-MF-E H3H3 Target Market Small- to medium-sized businesses General Specifications Digital Station Capacity 200 Line Capacity 80 Simultaneous Calls Possible 108 Switching Matrix Time division Type of Processor Centralized 68000 microprocessor Type/Amount of Main Memory (bytes) 896K RAM Port Capacity 280 As you can tell the system is can not handle as much as the PBX system but for small business the Merlin Legend is a perfect fit. The price of the key/hybrid system the basic Merlin Legend Release 7.0 module retails for US$1,494. As you can tell that is a steep difference in price between the two. In conclusion when comparing the key system and PBX you compromise the features and price. With the PBX of the Fujitsu you spend so much more money but you get a lot of different features as well as the ablility to grow and become a bigger corporation with larger features. The Key system just leaves you with the bare requirements for your small business
