A control block in the TCT for all non-VTAM terminals on the same line. The TCTLE contains all parameters necessary for processing requests for terminals on the line. For example, there are TCTLLEs for BSAM terminals on CICS Transaction Server and CICS/VSE, and for TCAM terminals on CICS Transaction Server only. The equivalent information for VTAM terminals is in the VTAM request parameter list (RPL).
