2.8 SHDSL-port (WAN-interface)
The BIG 101x has a 4-channel SHDSL-transceiver which is linked to the device via an RJ-45
connector. The pin assignment is shown in the figure below:

The BIG 101x works in NT-mode with disabled PMMS/Lineprobing method. This ensures
maintenance-free configuration, since fixed bit rate profiles are applied, while the settings for
negotiation of the transmission parameters are being controlled from the DSLAM side. When
using more than one line pair, the individual links are pooled to one bonding group (EFM-
bonding). Depending on the DSLAM settings, this allows for a bandwidth between 2.5 Mbps
and 10Mbps. Range increase is supported by using up to 8 regenerative repeaters (4
ZWR2MS-EFM for each amplifier with quadruple bonding).
