3.5.6 Master / Slave
To start up a DSL link, one system unit must be configured as master modem
(STU-C) and the other one as slave (STU-R). The master controls the link
startup procedure. If both system units are configured as master or as slave, no
startup will occur.
Usually, the Watson Ethernet plug-in is configured as master and the Watson
SHDSL router as slave (default setting). However, it is possible to set up a DSL
link with two Watson SHDSL router as long as one is configured as master and
the other one as slave.
3.5.7 DSL Clocking
Watson SHDSL router have a crystal controlled DSL clock that does not depend
on the clocking of the Ethernet user interfaces (clockmode 1 of TS 101 524).
3.6 Firmware update
Watson SHDSL router offers a built-in mechanism for upgrading its firmware,
without losing any custom configurations and settings. There are two methods
for upgrading the firmware:
 Upgrading from a local computer - use a firmware image file pre-downloaded
to your PC's disk.
 Upgrading from the Internet - also referred to as Remote Update, use this
method to upgrade the firmware by remotely downloading an updated soft-
ware image file.
3.7 Management
3.7.1 Management interfaces
Watson SHDSL router has several management possibilities:
 Web based management (WBM) locally through the Ethernet user interfaces
or remotely through the DSL link. The full management possibilities (configu-
ration, monitoring and alarming) are accessible using the WBM.
 SNMP management locally through the Ethernet user interfaces or remotely
through the DSL link. SNMP management is very limited, because it supports
only following MIBs: RFC 1213 (MIB-II), RFC 2011 (MIB for IP), RFC 2012
(MIB for TCP) and RFC 2013 (MIB for UDP).
 Telnet and SSH management locally through the Ethernet user interfaces or
remotely through the DSL link.
 DSL Embedded Operation Channel (DSL EOC): A Watson Ethernet plug-in
(SZ.866.V654) when configured as DSL master modem (STU-C) can man-
age the Watson SHDSL router through the DSL EOC.
