Step-by-step configuration
5.1 Configuring the basic line parameters
crocusShdslTtRpG703/line/channel
Default: remote
Range: remote / central
The channel attribute defines which modem is the central and
which the remote modem. I.e. it determines which modem acts as master and which as slave during the
synchronisation procedure of the modem.
The default channel setting of a TT is remote, while that of a CV is central. Therefore there will never be
a synchronisation problem when a CV and a TT are used in a regular set-up, the CV at the backbone
side and the TT at the customer side.
• If two TTs are used at each end of the data link, make sure to change the channel attribute of one of
the TTs into central.
• If two CVs are used at each end of the data link, make sure to change the channel attribute of one of
the CVs into remote.
