DM229x Series. Modems G.SHDSL EFM.
DM229x Series

The DM229x family integrates Metro Ethernet networks in the first mile of the networks of their customers through a G.SHDSL EFM interface (Ethernet First Mile) that enables data transfer up to 22.8Mbit/s, comply with EFM (IEEE 802.3) recommendation. Offers Ethernet solution on up to 4 twisted pairs of copper in the G.SHDSL interface. Also have one optional interface E1 pseudowire. Thus enabling a high-performance solution, adaptable according to the needs of the end customer.

  • Operates at variable rates ranging from 192kbit/s to 5.696kbit/s per pair. When operating at 4-pair bonding it can reach up to 22.8Mbit/s rate.
  • Has up to 4 Fast Ethernet 10/100BaseT interfaces featuring MDI/MDIX compliant to IEEE 802.3. Offers 4 pairs bonding.
  • Has 1 E1 pseudowire (PW) interface in compliance to RFC5086-CESoPSN e RFC4553-SAToP over twisted copper pair in a RJ48C 120 ohms connector.
  • CPE (NTU) or CO (LTU) operation.
  • The bonding configuration allows higher rates and greater reach in addition to, in case of failure of one pair, the connection remains active through the remaining pairs.
  • Supports VLANs and VLAN trunking compliant to IEEE 802.1Q.
  • AAA – Authentication, Authorization e Accounting with Local Authentication or TACACS.
  • Local and Remote Syslog.
  • Allows clock (time) synchronization of the equipment through NTP.
  • It is entirely manageable through an RS-232 port with an RJ45 connector.
  • Allows management through SSH and Telnet, using the Fast Ethernet port (LAN interface) or the G.SHDSL port (WAN interface).
  • QoS with packet marking and classification. Offers also rate-limiting and traffic-shaping.
  • SNMPv1 and SNMPv2.
  • Allows local and remote equipment firmware update.
