Cisco Multimode G.SHDSL Network Interface Module

Product Overview Designed to deliver high-speed Ethernet services over Symmetrical High-speed DSL (SHDSL) access, the multimode G.SHDSL NIM (Figure 1) offers symmetric data rates over one to four pairs of copper wire and supports both EFM and ATM modes. To achieve higher bandwidths, bonding of multiple pairs (4-wire, m-pair, inverse multiplexing over EFM bonding) is supported. In EFM mode, the multimode G.SHDSL NIM allows bonding, as defined by IEEE 802.3ah, and is typically used in scenarios where individual links are aggregated using the 802.3ah loop aggregation. Depending on the number of wire pairs in service, the maximum data rate is ...
