Description

ELF2-Rxx can be used on the primary E1 channels as IP router, bridge or firewall. The possible router modifications are listed in the table below.

As distinct from competitor products, the ELF2 router has the following advantages:

  • The second E1 port presence, which can be used for drop-insert schemes and daisy chain connections
  • The extended capabilities of CAS signalization in timeslot 16
  • The router is based on the Linux kernel, well proved system in telecom applications
  • Modular software gives additional flexibility in many applications

Router software is based on the Linux system and provides following functions (package version 2.40):

WAN protocols
Ethernet
Synchronous PPP
Several IP addresses in one interface
Cisco HDLC Remote IP changing
Frame Relay Access point IEEE 802.1Q (VLAN)
Two E1 aggregation into one link (for ELF2-REE)
