Fixed network local telephone service
Fixed network local telephone service refers to the telephone service provided through the local telephone network (including ISDN network) within the same long-distance telephone number area.
Fixed network local telephone service includes the following main service types:
-End to end two-way voice service.
-End to end fax service and medium and low speed data service (such as fixed network short message service).

The fixed network domestic long-distance telephone service includes the following main service types:
-End to end two-way voice service across toll number area.
-End to end fax service and medium and low speed data service across toll number area.
-Various supplementary services such as call forwarding, three-way call, caller number display across the toll number area.
-The intelligent network service across the toll number area provided by the local telephone network, long-distance network and intelligent network.
-Cross toll numbering area is based on ISDN bearer service.
