Meanings of the Error Codes
Chapter 2 35
Action: Correct the application source code. The receivers for a
terminal can be removed using the ZCOM zconfig()
routine (clear terminal function) or using the
zset_rcvr() and if needed, the zevent_rcvr() routine.
ZENOTDSB (-48): Must be disabled first
Explanation: The requested function requires the terminal to be
disabled. However, the terminal was found not to be in
the disabled state.
Action: Correct the application program. Issue the appropriate
ZCOM calls to disable the object before making this
request.
ZESUBCH (-49): Illegal subchannel number
Explanation: The application used an illegal subchannel number.
Subchannel numbers must be in the range 0 to 31 for
ACC E1/T1 cards and must be zero (0) for all other card
types.
Action: Correct the application program.
ZEHWUSED (-50): Hardware already in use
Explanation: The specified hardware bus and slot number is already
assigned to another interface card.
Action: Correct the application program.
ZELIMIT (-51): Dest. queue limit reached
Explanation: The data send request has failed because this would
cause the destination ZLU to exceed its transmit queue
limit. This can result if the default queue limit has
been set too small in the TTGEN configuration file
(Transmit-Limit parameter), the application is sending
data faster than it can be transmitted to the device, or
a defect in the design of the application program.
Action: Correct the application source code or increase the
destination queue limit.
