MULTI MODE 4 PAIR G.SHDSL EFM AND ATM MO

Cisco 4-Pair G.SHDSL EFM/ATM EHWIC

Designed to deliver high-speed Ethernet services over SHDSL access, the multimode G.SHDSL EHWIC offers symmetric data rates over one to four pairs of copper wire and supports both EFM and ATM modes. In order to achieve higher bandwidths, bonding of multiple pairs (4-wire, m-pair, Inverse Multiplexing over ATM [IMA], and EFM bonding) is supported.

In EFM mode, the multimode G.SHDSL EHWIC allows bonding as defined by IEEE 802.3ah, and it is typically used in scenarios where individual links are aggregated using the 802.3ah loop aggregation. Depending on the amount of wire pairs in service, the data rates can be 1 x 5.7 Mbps up to 4 x 5.7 Mbps with Annexes F and G. The EHWIC complies with the 2BASE-TL standard, which is based on the IEEE 802.3ah EFM standard. The 2BASE-TL standard uses the technology standard based on ITU recommendation G.991.2 bis.
