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. |
