Each D channel may be assigned two ten-digit phone numbers to be used for routing calls
addressed to those phone numbers. The use of the wild card letter “x” means any digit will

If local routing is disabled (Route Local = no), any call coming into the system on a network
side (i.e., local) D channel will be routed only to a user side D channel based on the called
number. Even if the called number matches, such a call will never be routed to an HSU port
or a network side D channel when local routing is disabled.

The routing table should always contain the default number "xxxxxxxxxx" (10 Xs) to make
sure that all dialed numbers are routed to the network.
