IP-PIPE G1620 (TDM over IP)
 
 
General Description
Featuring one E1/T1 ports, one LAN Ethernet port, and one WAN Ethernet port, the IP-Pipe
G1620 allows carriers and enterprise to seamlessly and reliably connect TDM-based leased
equipment and Ethernet users over a unified low cost wireless or wired Ethernet/IP-based
infrastructure without any voice quality degradation. G1620 operates transparently to TDM
signaling, ensuring seamless connectivity to any equipment that has physical E1/T1 interfaces
such as PBX, Cellular base stations, SS7 signaling equipment and voice mail systems.
The IP-Pipe G1620 supports precise E1/T1 clock transmission and recovery over packet
networks, and complies with ITU-T G.823 and G.824 timing standards while ensuring
uncompressed toll voice quality. The G1620 implements the emerging Metro Ethernet
Forum/IETF Pseudo-Wire Emulation Edge to Edge (PWE3) standard.
