CCSA Access
This feature allows connection to or from a CCSA (Common Control Switching
Arrangement) network. A CCSA network is a special, privately-leased network constructed
for one customer's exclusive use that replaces or augments the public switched network
services. The outgoing connections using CCSA lines are accomplished in the same manner
as a normal outgoing call. Incoming calls are received from the CCSA network as a series
of digits from the network instead of a ringing signal, and the connection is established in
the same manner as a Direct Inward Dial (DID) or Tie Line connection. For Tie Line
applications, the customers can construct a network with their own numbering plan. In a
CCSA application, the numbers are issued by the C.O. following the CCSA network
numbering plan.
Code Calling Equipment Access
Code Calling Equipment consists of external paging units and external dialers requiring dial
access from the

This feature permits dial access to customer provided Dictation Equipment, and in some
instances allows them to maintain telephone dial control of normal dictation system features.
