Added - D Channel status information to the Line Status page.

This is a Layer 2 status indicator for T1-PRI and E1-PRI lines. A status of "active" indicates the MultiAccess is communicating with the Central Office via the defined Switch Type (D Channel) protocol. This was changed in MultiAccess software (version 1.12). Please see Resolution 3376 for instructions on updating your MultiAccess MA30120.
