Extend Main Channel. This configuration option supports extended diagnostics. Specifies whether there is main (primary) channel connectivity between the modem’s DTE ports and the DTE ports of modems one level below (downstream) or above (upstream) in the diagnostic network.

HEnable

If this configuration option is set to Enable on a port of a tributary modem, test mode is propagated to the modems downstream when test mode goes ON for that port.

HDisable

If this configuration option is set to Disable on a port of a tributary modem, test mode is not propagated for that port and primary channel data is clamped when in test mode.

NOTE: For an extended control modem, this configuration option is used along with the upstream port number where the main (primary) channel is extended.
