32 Chapter 3 G.SHDSL Port Setup
3.3 Configured Versus Actual Rate
You configure the maximum rate of an individual G.SHDSL port by modifying its profile (see
the
SLC Edit Profile screen) or assigning a different profile to the port (see the SLC Edit
Port Setup screen). However, due to noise and other factors on the line, the actual rate may
not reach the maximum that you specify.
3.4 Default Settings
The default profile always exists and all of the G.SHDSL ports use the default profile settings
when the G.SHDSL line card is shipped. The default profile's name is set to
DEFVAL .
3.5 N-wire Mode
The n-wire mode allows you to physically bundle two G.SHDSL ports into a single 4-wire
connection. The 4-wire mode is described in ITU-T G.991.2. You can use it to connect to
G.SHDSL modems or routers that also support 4-wire mode. N-wire mode also allows you to
physically bundle four G.SHDSL ports into a single 8-wire connection. The 8-wire group is
proprietary and should be used between two SLCs. The 8-wire group is called mpair4
N-wire mode can increase the reach of a particular data rate without having to regenerate the
signal. It can also give increased bandwidth for LAN-to-LAN applications.
You can n-wire bundle multiple groups of ports on a single SHDSL line card.
