DAWN 2200
VOICE/DATA MUX

Features:

• Multiplexes 4 user ports into 1 digital link 
• Built-in 56Kbps DSU/CSU(optional) 
• 2 - RS-232 and 2 - RJ11 interfaces 
• PBX line and loop-start trunk compatible 
• Supports DTMF and pulse dial signaling 
• 16Kbps ADPCM voice compression 
• Full non-blocking TDM, both voice and data 
• Use of VLSI technology for high reliability. 

Benefits

• Saves cost of expensive multiple links 
• Saves equipment clutter and costs
