Description

ELF2-PP gateway is intended for virtual E1 channel creation in the packet networks. The device enables to organize traditional telephone channels on the Ethernet infrastructure. Being more suitable alternative in some instances, this approach considerably simplifies telephone channel installation and operation as compared with VoIP.

There are the following operational requirements for ELF2-PP gateway:

• broadband point-to-point Ethernet connection with 10 base T or 100 base T interfaces
• QOS support in the switching equipment if data is transmitted through the same channel
• small round-trip delay (less than 30 ms); otherwise E1 echo suppressors should be used

The main features of the ELF2-PP gateway are the following:

• Transparent telephone signalization, both CSS and CAS
• Exact E1 frame and multiframe regeneration
• Exact G.703 time and frequency parameters regeneration
• Jitter compensation for Ethernet packets
• E1 data is encapsulated to UDP or raw Ethernet packets
• Packets size and jitter buffer length are controlled
