IP-6440 Inverse Multiplexer

The IP-6440 was replaced with the higher performance IP-6416 Inverse Multiplexer. The IP-6416 provides connectivity between 10/100/1000BaseT/GbE and up to 16 T1 or E1 Lines.

How to Order

  • Support WAN link, which is virtually concatenated n x E1 (n can be 1 to 4)

The Loop-IP 6440 IP Inverse Multiplexer provides connectivity from 10/100 BaseT LAN to a E1 WAN through multiple E1 channels, Supports up to 4 E1 links. The IP 6440 also provides a bridging function from Ethernet to E1 links. This unit supports from 2Mbps to 8Mbps network bandwidth, fully utilizing the E1 inverse multiplexed link bandwidth.

The IP 6440 offers automatic E1 channel failure detection and can re-assign the number of E1 channels for transport of Ethernet traffic. For example, if there are 4 E1 configured for 10/100 Ethernet traffic transport, and one E1 fails during the service, the other 3 pick up the entire load. This minimizes loss of IP packets.

The Loop-IP 6440 supports management through a DE-9S (PC 9-pin) console port, which provides in-service diagnostics and fault isolation from a local or remote terminal. Remote site telnet management is available through the Ethernet port or Ethernet link. The IP 6440 series also provides multicolor LED indicators on the front panel and ACO (Alarm Cut-Off) button.

Interface Modules

E1 module

  • Line Rate 2.048 Mbps
  • Jitter : ITU G.823
  • Line Code AMI/HDB3
  • Input Signal ITU G.703
  • Data Rate: n x 30 x 64Kbps (n=1 to 4) or n x 29 x 64Kbps (n=1 to 4)
  • Jitter ITU G.823
  • Electrical 75 ohm coax bnc / 120 ohm twisted pair

Ethernet module

  • Data Rate10/100 Mbps
  • Connector RJ-45 connector
  • Management via Telnet and embedded SNMP
  • Mapping N x DS1 (Up to 4 E1 lines)

The IP6440 is commonly used when a single E1 doesn't provide enough bandwidth to link remote 100BaseT LAN locations and T3/OC-3 links are too expensive or unavailable.
