2. Copyright: Valiant Communications Limited - 2010Slide 2 2 x E1/T1 over Ethernet Multiplexer (TDMoIP) Product Overview  VCL - 2 x E1/T1 over Ethernet (TDMoIP) provides the user with E1/T1 over Ethernet (IP) conversion and allows the user to transport E1/T1 channels (carrying data or voice) over Ethernet (IP) Network.  Very Compact and low cost.  It is an E1/T1 extension device which utilizes the Ethernet / IP Network to transport E1 or a T1 signal in real-time.  Useful for the Real-time applications carrying VOICE, VIDEO and DATA.  It can be installed and used in multiple locations in a point-to-point or point to multipoint topology, depending upon the user requirements.  Compatible with 1 port, 8 port and 16 port TDMoIP versions.  The QoS features include short and stable transmission delay, low jitter and wander etc.
