You are using DPL (Distributed Program Link), which requires a PPT entry in the local region, pointing to the REMOTESYSTEM (SYSID) of the CICS region where the program is defined. The remote region also requires a PPT entry as well or AUTOINSTALL will work too.
An EIBRESP of 53 is a SYSIDERR, which indicates that the SYSID defined to the local PPT entry is invalid or perhaps, not in service.
An EIBRESP2 of 28 (from the manual) states -
The remote system specified by SYSID is not in service. This response can also indicate that the transaction has not been defined on the remote system.
You need to speak with your CICS System Programmer(s) and/or Tech Support group about these errors.
