ASMi-52L is an SHDSL modem that operates in full-duplex mode over 2-wire and 4-wire lines. Multiple data rates in the range of 64 to 4608 kbps are supported. Data rates depend on the line interface, DTE interface types, and operating clock modes. The Access Company ASMi-52L employs standard SHDSL TC-PAM technology to extend the transmission range (see Table 1) and enable carriers to reach more customers at lower costs.
