Chapter 6 Cisco IGX 8400 Series Data Service
Data Service Provisioning
To set up a data connection, use the following procedure:
Step 1 Add the connection to the data channel with the switch software addcon command.
Step 2 (Optional) Specify the clocking for the data channel with the switch software cnfdclk command.
Step 3 Continue with additional channel configurations as needed.
Configuring an Interface Control Template
Interface control templates define how the control leads at the data interface are to be configured
(asserted, inhibited, follow a local source, or follow a remote source).
To configure the interface control template to fit your particular needs, use the following procedure:
Step 1 Configure the interface control template with the switch software cnfict command.
Note You must configure each template and each control lead individually.
A DCE terminates a network circuit, converts bits received from the DTE to the proper bit encoding for
the network, and usually provides bit clocking for the DTE. DCE equipment includes modems,
CSUs/DSUs and switch interfaces.
DTE and DCE interaction requires use of control leads, which indicate when the DTE can transmit data
and let the DCE know that data is incoming, and data channel clocking based on oscillators in the DCE
or DTE equipment.
Interface control templates (ICTs) provide a way to manage outbound control leads on the data channel.
The ICT defines outbound control lead states (off or on) for the data channel depending on the current
state of the associated connection. For example, an ICT could specify that the outbound control lead,
DSR, be turned off if the connection fails.
The following ICTs can be specified for each data channel:
• Active (a)—the connection status is active.
• Conditioned (c)—the connection status is failed (or down).
• Looped (l)—the connection has a software-configured loop in progress.
• Near (n)—the connection has a near-external modem loop in progress.
• Far (f)—the connection has a far-external modem loop in progress.
For more information on control leads and ICTs, see the “Configuring an Interface Control Template”
section on page 6-3.

page 2-76 and the “Low-Speed Data Module” section on page 2-81 in Chapter 2,
