Functionality

ASMi-52 can be configured to operate in a CO (central office) or CPE (customer premises equipment) mode.

Line Interface

ASMi-52 extends the range of data transmission over 2/4-wire lines up to 7.0 km (4.3 miles), by employing SHDSL TC-PAM technology. ASMi-52 operation complies with the requirements of the ITU-T G.991.2 standard. In addition, 4-wire ASMi-52 units can be configured to operate over 2-wire lines.

Table 1-1lists typical ASMi-52 ranges over 2/4-wire 26 AWG line.
