Advanced CSL SCI requests

After connecting to Structured Call Interface (SCI), an IMSplex member can use advanced SCI requests to request services from and find out information about other IMSplex members. Each advanced request has its own purpose.

After establishing the connection with SCI, an IMSplex member can use advanced SCI requests to:

Communicate, or request services, from other IMSplex members.
A message protocol and a request protocol are provided to facilitate communication among IMSplex members. A message is a one-way communication with another IMSplex member. A request requires that a response be returned to the requesting member.
Find out information about the other members in the IMSplex.
A query request, CSLSCQRY, allows an IMSplex member to find out who the other members of the IMSplex are and to obtain information about those IMSplex members.

The following table lists the advanced SCI requests with their purpose. These requests can be issued without regard to sequence; however, the IMSplex member issuing the request must have registered to SCI.
