SHDSL Loop 1 Interface Mode Menu
The SHDSL Loop 1 Interface Mode menu (see
Figure 5-53 ) is used to set the interface mode.
The interface mode can be set to either 2-wire or 4-wire. SHDSL transceivers are designed
primarily for duplex operation over mixed gauge 2-wire twisted metallic pairs, however,
optional 4-wire operation is supported for extended reach applications.
