THIRD PARTY CTI - CSTA APPLICATIONS
Ed. 044/16 Réf. 3EH 21000 BSAA
DESCRIPTION OF THE CSTA LINK (SYSTEM <-> SERVER)
PRESENTATION
The CSTA link is the one which connects the system's CSTA server to the CTI server. It consists of an
Ethernet link supporting a stack of BSD4.3 compatible TCP/IP protocols for the lower layers and OSI-
compliant ACSE/ROSE/ASN1 for the higher layers. The RFC 1122 and RFC 1058 recommendations
are also adhered to.
LINK MANAGEMENT
Initialization
To initialize the link, the CTI server must connect to the transport layer (TCP protocol) on TCP port
2555. Once this connection is made, the application identifies itself at session level (by sending the
character 'B'), the system then responds by sending the character 'P'.
Message Transmission direction Meaning
B CTI Server -> System Identification of the application
P System -> CTI Server CPU
EXIT CTI Server -> System End of connection
